Notes is a core feature of the OpenStreetMap.org website. It enables you to add a comment on the map to assist others in mapping/editing OpenStreetMap. Other users can respond to your notes, for example to ask for additional details if necessary.
Example of valid and useful note can be "a new road was constructed here" or "this shop is closed and not existing anymore".
Please do not use notes for general discussion or storing information not otherwise used in OpenStreetMap. For example never create notes such as "I was here on Saturday" or "There was a crime at this location".
Although it is not necessary to be logged in to submit a new note, it is beneficial to do so. Logged-in users will receive an email if comments are added to a note or the issue is resolved.
The notes feature of OpenStreetMap allows both registered users and the wider public to quickly indicate where there are errors or omissions in the OpenStreetMap data, and for contributors to OpenStreetMap to know where their support is needed.
To add a note, click the bottom tool bar button on the right side of the main OSM map.
Move the marker to the correct position (as accurately as you can). Leave a short text message for contributors to Openstreetmap to tell them what's wrong or missing.
Be clear in your message, for example consider that "path wrong" says very little of use, but "The east-west path on the map does not exist on the ground" is very clear.
If you have an OpenStreetMap account, you should login first to have your note associated with your username, but casual visitors can easily add a note too. If you want to be more than a casual visitor, create an account.
Entered text is treated as a plain text, though for example openstreetmap.org will recognize and autoformat links. Formatting with markdown is not supported - unlike private messages and diary entries.

Finding your notes
To easily find unresolved notes created by (or commented on by) some user (such as your own notes), you can use My OpenStreetMap Notes service.
To view all the current notes for an area go to the openstreetmap.org main map display, click the 'layer picker' control on the top right of the map, and select the 'Notes' checkbox (see image).
The note markers have the varying styles shown in the image below:
|New note location (while being added)|
|Unresolved note location|
|Resolved note location (older such notes will not be shown)|
After selecting a note, you can comment on it, for example, to ask the contributor questions (if they were logged in when adding the note) or to add additional information.
Notes that are no longer valid should be marked as resolved (requires log in). For example, a note that relates to a map error should be marked resolved once the map has been updated to fix the error. Duplicate or invalid notes should also be marked as resolved.
Resolved notes are not removed or deleted. After a period of seven days they are hidden from view. Hidden notes can be viewed using the RSS feed and the
closed=-1 parameter like this:
See this question on the OSM Help forum for more details about how to view hidden notes.
It is also possible to report notes using the »Report this note« link at the bottom (requires log in). This should only be done in the case of notes containing abusive or illegal content, or where sensitive or confidential information appears in notes. All other kinds of problem, including spam, should be tackled by resolving the note with a quick message explaining what the problem was. If we report a note, then volunteers in the data working group need to process this. They can permanently hide inappropriate notes, but it's better not to place demands on their time if this is not required.
Monitoring notes in a selected area
You can use NotesReview to visualize all notes on the map.
Generating a custom RSS feed
First, you need to know the coordinates of the area (bounding box) you want to monitor. You can use the OSMCha filters to do so.
Then, copy-paste them at the end of this url :
List for a country
Overview about Open/Closed OSM Notes is going to be useful.
Anton's note viewer
https://antonkhorev.github.io/osm-note-viewer allows you to search notes for user, text, or date range, and get all notes inside a small specified bounding box.
Monitoring notes by a specific user
Generating a custom RSS feed
The following URL returns the nodes of the given OSM username as RSS/Atom feed. Replace USERNAME in the URL.
Support in editors
OSM editors offer various support for notes.
iD and JOSM can show and act on them but it requires using special option.
Vespucci downloads and shows notes by default, together with Osmose errors.
StreetComplete shows notes that include questions and can be configured to show all of them. StreetComplete users can also manually leave notes, especially when objects for given quest is outdated (for example user is asked about opening hours of shop that is gone). StreetComplete has special support for easy way of making photos and including them in a note as links.
