This page describes a key prefix rather than a simple key.

This key page is a stub. You can help OpenStreetMap by expanding it.
Similar pages for structural reference: Key:religion, Key:waterway.

This namespace prefix appears to complement the primary addr:*=* keys, and used to indicate additional official address information of a feature.

Several but separate Wiki pages outlining a draft to formalize this namespace tag were found:

• Proposal:AddrN (2015)
• Proposal:Multiple addresses
• Proposal:AddrN (2010)
• Proposal:AddrN (2012)
