The contact tag is the prefix for several contact:* keys to describe contacts.

Popularity of phone=* and contact:phone=* indicating ongoing and uninterrupted preference of simple tagging scheme over contact: prefix

For the most common keys, the shorter version outside the 'contact' scheme is used more frequently, over the time until now: phone=*, fax=*, email=* and website=*, with other contact tags used rarely outside the namespace scheme. Both schemes are in use for a long time and exist in parallel. Many applications are able to use both of them.

To limit tag fragmentation, consider using the most used keys.

At the same time a proposal to deprecate contact:phone=* was not successful - Discussions/tagging/contact:phone or phone. Idea of deprecating either tags without contact: prefix or ones with contact prefix is repeatedly suggested, often triggering huge discussion and ending with conclusion that there is no consensus. Please, read past discussion before starting a new one.

Values

You should only add contact information to POIs and not to any private address!

Email-addresses which are only available on a website after solving a captcha, or which are in other ways obfuscated to protect against SPAM-bots should not be tagged in OSM. The same applies to fax and phone numbers.

What is used here: Phone and fax number format ( DIN 5008): +<country_code> <national_destination_code> <subscriber_number>-<direct_inward_dialing>
