# NAP (Name, Address, Phone)

> What NAP means: Name, Address, Phone. Why inconsistent NAP data leads AI assistants to recommend your business with wrong information.

Synonyms: NAP, NAP data, NAP consistency, Name Address Phone, business data consistency

NAP is short for Name, Address, Phone. These are the three details a customer uses to find and reach you. NAP consistency means these details are identical and current everywhere: your own site, map services, booking portals, business directories, social profiles.

The problem arises when the same detail differs across places: an old phone number here, outdated opening hours there. Directories often copy their data from each other, so a single error spreads further.

For AI visibility, NAP consistency is decisive: AI assistants draw their answers from exactly this directory data. If it's contradictory, the AI recommends your business with wrong information — worse than not being recommended at all.
