Free The Postcode
Free The Postcode (freethepostcode.org) is a free database of postcode-to-location mappings. They are asking people with GPS Receivers to submit their copyright-free latitude/longitude readings for any particular postcode.
This is a Related Project, in fact it's a sister project of OpenStreetMap, set up initially by the same guy User:Steve. Clearly the aims overlap quite nicely with some of the activities of OpenStreetMap, so we can help each other out.
See also OpenStreetMap FAQ which has some information relevant to FreeThePostcode.

How to easily get postcodes
Enter postcodes as waypoints in your GPS unit. Then when you get home you can go through them and send them to freethepostcode. If you don't know the postcode, it's fairly easy to figure out well-known places. For example, take a waypoint outside a pub then go and google for the pubs address. Bingo, you have the postcode.
A good source of post codes is phone boxes. In some parts of the UK most phone boxes have their full postal address on a small label inside (this is so that a caller can tell the emergency services where they are).
Another good source is businesses with local branches/stores (banks, supermarkets, etc). Most have a list of stores (with postcodes) on their web site.
John McKerrell has written an application for the iPhone which makes it really easy to submit postcodes using the in-built GPS on the newer iPhone models. More information on that can be found on the iFreeThePostcode support page. The application is open source and free to install (via the iTunes App Store).
Windows Mobile Application
Chris Cowley has written an application for Windows Mobile devices, based on the look and feel of the iPhone application, which makes it really easy to submit postcodes using the in-built GPS on newer Windows Mobile phones. More information on that can be found on the author's web page.
The basic geocoder can get from postcode to lat/lon and back:
The postcode geocoder knows not to fall back on N-something if you ask it for NW-something. It will give you the closest match it can. You can make it better by collecting more postcodes. The format should be pretty obvious and not subject to change. Lines starting with a hash are comments, see also http://www.freethepostcode.org/currentlist
- Enter OSGB coords rather than lat/lon
- Enter eastings and westing rather than positive and negative numbers
- Enter coords in degrees, minutes, seconds
- Not just UK - eg freethepostcode.org/norway
- Upload by GPX waypoint names (would need to validate postcode formats vs waypoint names, and many Garmin GPS receivers only allow 6 character waypoint names, which means only a subset of UK postcodes can be done this way). This avoids co-ordinate keying errors.
- Accuracy information - eg if a user requests OX1 4AU then if we don't have an exact match we can return a location based on OX1 4xx or OX1 xxx or OXx xxx with an estimated error based on average sizes of zone/district etc.
- this is already done, the geocoder returns the best match available and tells you which one it's giving back, try it :-)
- Sure, but this isn't good enough for an end-user application where we want to say "this postcode is here, plus or minus xx m/km". The implication here is that we need to store some information about the size of each postcode zone. --Dom.
- This is an issue for non-residential codes especially - my work postcode covers a site about 500m across. Should I measure the postcode somewhere in the middle of the site (looking the postcode up on google maps etc provides a point vaguely, but not exactly in the middle) or should I provide the location of the actual entrance? Even the latter is difficult, as the visitors' entrance used to be on one side of the site, and is now on the other... --DA
- Incidentally, can we have a mailing list for freethepostcode? It'd make this sort of discussion easier --Dom.
- Allow people to amend postcodes they enter, or at least to reject codes when the confirmation email arrives. I very stupidly put in the wrong coords whilst going through a list I gathered, and ignored the email but trying it a second time with the right coords doesn't seem to have worked -- Tom.
- Please can we have a means to enter postcodes by clicking a position on an OSM map? Surely this is free of copyright? I could add quite a number of postcodes I know from memory but don't have the time to take a GPS to. Thanks, Daveemtb 18:34, 19 November 2008 (UTC)
This might need some different approaches for different countries
For the format, consult wikipedia: .
There is an up-to-date list available from the Austrian Post website that associates each postal code to (parts of) municipalities; it consists of 5 columns, giving the community, Bundesland (federal state), municipality, postal code, denomination of the post office. In order to use those data for OSM, the Austrian Post should probably be asked first if that's okay for them. As postal codes tend to be rearranged sometimes, a script checking for changes in that file might then be quite useful.
To a rough approximation, the first digit 2-7 covers six states (2=NSW, 3=VIC, 4=QLD, 5=SA, 6=WA, 7=TAS) with territories either 0nnn or 2nnn. See wikipedia page. The Australian postcode database is a zero-cost download from Australia Post, but with copyright and usage restrictions.
Each commune has his one. The two first numbers give the province.
10nn 11nn 12nn are for Brussels
13nn 14nn are for the Brabant Wallon
15nn 16nn 17nn 18nn 19nn are for Vlaams-Brabant
2nnn are for Antwerpen
30nn 31nn 32nn 33nn 34nn are also for Vlaams-Brabant
35nn 36nn 37nn 38nn 39nn are for Limburg 4nnn are for Liège
5nnn are for Namur
60nn 61nn 62nn 63nn 64nn 65nn are for Hainaut
66nn 67nn 68nn 69nn are for Luxembourg
7nnn is also for Hainaut
8nnn are for West-Vlaanderen
9nnn are for Oost-Vlaanderen
Each street os cities bigger than 50,000 habitants have their it own code, big avenues can have more then one, such as one for each side. Some special buildings, such as big offices or any other places that receive lots of mail can have it's own code as well.

Accurate to street segment and side if the second digit is non-zero. If the second digit is zero, it identifies a whole community and is not subdivided (rural postal code; a municipality might be split between codes, though, as with U.S. zipcodes). Postal codes ending in 0 identify post offices, counters and similar facilities.
The first digit indicates the province, roughly east to west:
- A = Newfoundland
- B = Nova Scotia
- C = Prince Edward Island
- E = New Brunswick
- G,H,J = Quebec
- H = Montreal
- K,L,M,N,P = Ontario
- M = Toronto
- R = Manitoba
- S = Saskatchewan
- S7 = Saskatoon
- T = Alberta
- V = British Columbia
- Y = Yukon
- X = NWT/Nunavut
not street level. (areas)
The number denotes a 'Zustellbezirk' (postal district)
- 1. Number: Zone
- 2. Number: Region
- 3-5 : district
Postcodes are assigned by the German Post, as suited best for their postal needs:
Most of the time a city or commune has just one number.
Bigger cities have more than one (Frankfurt/Main: 37 between 60311 - 60487)
Villages may share one number with other villages or a town nearby.
- The number can have leading zeros because 0 is a valid zone
- The postal districts have no relation to the city districts
- The postal districts may exceed the borders of counties or even federal states
- Single locations may use the postcode of the nearby office which delivers post best, even if located within another postal area otherwise.
- There can be seperate numbers for P.O. Boxes or large institiutions (e.g. businesses receiving large ammount of mail) where no real street or geolocation can be assigned.
- A street might pass more than one postal district

The Faroe Islands, which are part of Denmark, used to be part of the danish postcode system, but now have their own 3 digit postcodes, so even when sending letters from Denmark "FO-" has to be prepended the postcode. The danish Wikipedia article for Faroe Islands postcodes is here.
Greenland however is still part of the danish postcode system and uses the range 3900-3999.
Un código postal español (Código Postal) consta de cinco dígitos, los dos primeros dígitos se derivan de una lista por orden alfabético de las 50 provincias españolas - a partir de 01nnn ÁLava/Araba y termina en 50nnn de Zaragoza. Códigos postales 51001 a 51005 se utilizan para las direcciones de Ceuta y 52001 a 52006 para las direcciones en Melilla (los territorios españoles en el norte de África). Hay un poco de confusión para los códigos postales Asturias que comienzan con los dígitos 33nnn (en lugar de 05nnn), porque antiguamente, era conocido por su nombre de la ciudad capital, Oviedo. Ese es también el caso de Cantabria (39nnn), que fue conocida anteriormente como Santandero La Rioja (26nnn) por Logroño.

Smaller numbers in the south, bigger in the north
There's a service for mapping between street / city and postal code at http://www.itella.fi/online-palvelut/tyokalutjalaskurit/postinumerohaku.html
All French addresses use a postal code ("code postal" in French), written before the commune name on the same line.
These postal codes are not assigned up to the street level, but are assigned for each postal distribution area organized from a local post office.
French postal codes have 5 digits, generally with the following format when based on local geography:
- 1-2 : number of the metropolitan department, from 01 to 95.
- The postal code may have a leading zero because 01 to 09 are valid department numbers.
- Postal codes for locations in Corsica keep using the prefix "20" and not the two distinct department codes "2A" and "2B" assigned later by INSEE.
- The new department of Rhône and the new Métropole de Lyon (both created in 2015) continue to use the same prefix "69" assigned to the previous department of Rhône.
- 3-5 : number of the postal distribution areas organized by post offices located in that department. The number "000" is used in most departments in its main city.
or outside metropolitan France:
- 1-3 : Overseas departments and collectivities, numbered between 971 and 989 (like INSEE codes).
- 4-5 : Postal distribution area organized by post offices located in that department or collectivity (here also "00" is also used in their main city).
or nationwide special postal codes:
- 1-2 : 99 for institutions (army), or for special locations abroad, or for large organisations (CEDEX).
- 3-5 : special distribution codes for each specific institution or organisation.
French postal codes must never be confused with 5-figures INSEE codes assigned to each commune, and which are almost always different in their last digits.
Postal codes have been assigned historically by the French Post, as suited best for their postal needs:
- There exists additional (non-strictly geographical) postal codes for P.O. boxes, or special "CEDEX" codes for organisations with special distribution (e.g. businesses receiving large amount of mails).
- In most communes, there's just just one postal geographical code, but the effective postal distribution areas have no relation to commune boundaries.
- Several communes may share the same postal code with other nearby small communes.
- The postal distribution areas may even exceed the borders of arrondissements (counties) or even departments or regions by several kilometers, or just for houses in the same street separating two communes, or for houses accessible only by a road coming from another commune.
- In large metropoles (Paris, Lyon, Marseille) the standard postal codes are simply assigned with one for each city district (municipal arrondissement) (e.g. Lyon uses postal codes 69001 to 69009).
- Others cities may also have more than one postal code (e.g. Saint-Étienne-sur-Loire: 42000, 42100...) (which could also span other nearby communes).
- Isolated locations anywhere may use the postal code of another nearby office which delivers them post the best, even if they are otherwise located within another postal distribution area.
- Postal codes may eventually change over time when post offices are reorganized, or after several communes have merged, so that they'll use the same (but this is not always true as postal codes may still be useful to distinguish postal addresses if there are homonymous streets or locations after the merge).
Shown format is ISO format for postal code use in Croatia, in standard use is also 5 digits number without "HR-" prefix.
The code is divide by bigger city in which Croatian Post have major distributing center :
10000 Zagreb Area 20000 Dubrovnik Area 21000 Split Area 22000 Šibenik Area 23000 Zadar Area 31000 Osijek Area 32000 Vukovar Area 33000 Virovitica Area 34000 Požega Area 35000 Slavonski Brod Area 40000 Čakovec Area 42000 Varaždin Area 43000 Bjelovar Area 44000 Sisak Area 47000 Karlovac Area 48000 Koprivnica Area 49000 Krapina Area 51000 Rijeka Area 52000 Pazin Area 53000 Gospić Area
Mostly Post use central city of County for distributing center. Also Croatian telecom use first two digits for prefix number when you call phone number in Croatia.
Postal code is assigned to post office, not particularly for area, so it will be nice to submit coordinate of postal office with exact postal code.
All code are freely available (and very accurate) on Croatian Post web pages.
It has been verified that Croatian postcode database may be imported in OSM.
Every postcode in Budapest (the capital of Hungary) starts with number one, like this: 1nnn. Then the 2nd and 3rd character tell the districts (23 districts exist is Budapest). So a postcode like 1028 can be found in the 2nd district within the city. Other areas in the country has different method, follows clockwise order from NortEast (3nnn) to NorthWest (9nnn), however the Budapest agglomeration usually starts with number 2 (2nnn).
The Republic of Ireland currently does not use postcodes at all, the closest thing being the Dublin and Cork Postal Districts, of which only the Dublin ones are ever used on letters. A Dublin postal district is similar to the old pre-postcode UK ones, and is included on the postal town address line in the format "Dublin 15".
Odd-numbered postal districts (1-17) are north of the river Liffey, even-numbered ones (2-24 and 6W) south (with slight spillover in at least one river-spanning suburb). Dublin 6W is an anomaly to the system caused by address snobbery triggered by a boundary adjustment that threatened to include a slightly-upmarket district with its middle-class neighbours.
Cork's postal districts go from 1 to 4.
A project is in progress to devise and implement a countrywide postcode scheme, with 2011 the currently suggested date for a rollout. Although details of the scheme are not yet clear, Postcodes are likely to be street-level and at least at townland resolution in rural areas.
In India postal codes or PIN codes are 6 digits without any letter prefix or suffix. Sample codes:
* 1xxxxx - Delhi and most North India * 4xxxxx - Mumbai and most Western India * 5xxxxx - Hyderabad * 7xxxxx - Kolkatta and most Eastern India * 6xxxxx - Chennai and most South India
On a general basis, they are on town level.
This cities have street level granularity:
Alessandra, Ancona, Bari, Bergamo, Bologna, Brescia, Cagliari, Catania, Cesena, Ferrara, Firenze, Foggia, Forlì, Genova, La Spezia, Livorno, Messina, Milano, Modena, Napoli, Padova, Palermo, Parma, Perugia, Pesaro, Pescara, Piacenza, Pisa, Ravenna, Reggio Calabria, Reggio Emilia, Rimini, Roma, Salerno, Taranto, Torino, Trento, Trieste, Venezia, Verbania, Verona .

Lithuania since 2005 has had a 5-digit postcode system, LT-xxxxx.
Current Lithuanian postcodes can be obtained using a search engine on the website of Lietuvos Paštas.
There was a four-digit system from independence until 2005, based upon the last four digits of the old USSR postcodes.
Latvian post codes are managed by Latvian Post. Code consists with letters LV and for digits like LV-xxxx If code is in Riga then it is in interval 1000 - 2000. Outside Riga codes are bigger than 2000.
You can find any Latvian post code by going to this link
The full postcode looks like MD-nnnn, where the first two numbers indicate the city/district, and the latter - the post office code.
65xx - Anenii Noi 67xx - Basarabeasca 31xx - Bălţi 47xx - Briceni 39xx - Cahul 73xx - Cantemir 44xx - Călăraşi 43xx - Căuşeni 61xx - Ceadîr-Lunga 20xx - Chişinău 41xx - Cimişlia 38xx - Comrat 48xx - Criuleni 51xx - Donduşeni 52xx - Drochia 4571 - Cocieri 46xx - Edineţ 59xx - Făleşti 50xx - Floreşti 49xx - Glodeni 34xx - Hîncesti 68xx - Ialoveni 63xx - Leova 64xx - Nisporeni 71xx - Ocniţa 35xx - Orhei 54xx - Rezina 56xx - Rîscani 62xx - Sîngerei 30xx - Soroca 37xx - Străşeni 72xx - Şoldăneşti 42xx - Ştefan Vodă 74xx - Taraclia 58xx - Teleneşti 36xx - Ungheni
the first two digits denote city or region; the remainder denotes the delivery route, down to street side and segment. There is a scheme that uses a check digit to denote odd street number, even street number, or even boat moorings, which is easy enough to implement to check validity of addresses.
Postcode / area:
0100-1299 Oslo 1300-1999 South East region (Østfold county) 2000-2999 Central East region 3000-3999 Central South region (Vestfold, Telemark counties) 4000-4999 South (Agder, Rogaland counties, Stavanger, Haugesund) 5000-5999 West (Hordaland county, Bergen) 6000-6999 North west region (Ålesund, Molde) 7000-7999 Mid Central region (Trøndelag counties, Trondheim) 8000-8999 Low north (Nordland) 9000-9999 High north (Troms, Finnmark, Svalbard)
Nrk/YR is [making an effort] to make a free database

Like Croatia / Slovenia - assigned to the post office. In most cases first three digits identify city (nn-nxx). Consult wikipedia for more details: 
First two digits are marking the county (region). More details on 
Not street level, usually in densly populated areas a street have more than one postcode, but where the population is more sparse there might be many streets per postcode. I did a fast count of the number of people per postcode and came up with 1000 per number, in Stockholm.

Like in Croatia ([Free_The_Postcode#HR HR]) postal codes in Slovenia are assigned to a post office, not to a particular geographic area, although an office has assigned places (city, villages...). Bigger companies (national television station, mobile operators, newspapers...) get their own 4-digit post code.
Post code finder and download: http://www.posta.si/Namizje.aspx?tabid=76
the first two digits denote province, as also used for vehicle licence plate prefix. Not street level.
nnnnn or nnn.
I had fun exploring the Taiwan Post Office's postal code CDROM. They hand it out free at the post office, and one finds no copyright notice on it. The CDROM is better than their website, http://www.post.gov.tw/ , which doesn't expose the innards.
the initial alpha(s) are a mnemonic for city or region. All of Northern Ireland is BTn(n), despite containing several cities. London on the other hand is divided into several regions. Quite complex to parse/validate. Mnemonic look-up tables will be needed.
Girobank post codes are an exception (GIR naa) - see the PAF digest The first part of the postcode is known as the "Outward" part, and the second part is the "Inward" part. Typically, the "Outward" part relates to one, and only one postal town, though there are some exceptions.
A lot of the impetus for the Free The Postcode project came from the UK, where postcode data was not freely available. To some extent the project has succeeded, as Ordnance Survey were forced to release postcode locations data for Great Britain as part of the their open data releases, in a dataset called Code-Point. See OS Opendata#Code-Point Open. However that dataset only has centroid points, whereas a postcodes are actually polygons, or even a "point cloud", and so the Free The Postcode dataset still can potentially add value in the UK. Even so, the OS data release rather reduces the project's value in the UK, but Free The Postcode helped to make that happen!
The OS Opendata does not include Northern Ireland postcodes (which all begin BT). However these postcodes (along with the Great Britain codes) are part of the Office of National Statistics (ONS) Postcode Directory (National Statistics Postcode Products). It is essential to note that the Northern Ireland postcodes in this dataset have eastings and northings on the OSI, not the OSGB grid.
The ONS dataset also contains creation and expiry dates of postcodes where known, and it includes some postcodes (denoted by an expiry date in the past) which are no longer current, hence it is important to check the expiry date when there is no interest in obsolete postcodes.
There's an old page tracking UK coverage at Free The Postcode UK Coverage
British Crown Dependencies
Postcodes have been allocated for the Isle of Man (IM) and the Channel Islands (GU, JE). These are formatted and allocated in an identical manner to the UK. The postcodes are present in the ONS dataset but unfortunately without coordinates.
UK Overseas Territories
Several of the UK's Overseas Territories have now been allocated a postcode (one single postcode per territory). They are generally a four letter code (based on the territory name), followed by 1ZZ. One exception is for Gibraltar, which uses a postcode of GX11 1AA. Wikipedia has an apparently full list of them.
The Gibraltarian authorities have stated that GX11 1AA is a temporary postcode until they devise their own system, based on that of the UK. .
the alphas denote state, the nnnnn seem to be low in the Eastern US, high in the West. The -nnnn suffix brings zipcodes down to the carrier level. The street address and zip+4 is all the address that is needed in the USA.
0000-2999 Northern Region (Gauteng, Mpumalanga, most of North West, Limpopo) 3000-4999 Eastern Region (Kwa Zulu Natal, eastern part of Eastern Cape) 5000-6699 Southern Region (Eastern Cape, eastern parts of Wetsern Cape) 6000-8299 Western Region (Western Cape (Cape Town and West Coast), Northern Cape) 8300-9999 Central Region (Northern Cape and Free State) (excluding 9000-9299, formerly South West Africa)
