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.

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.
