What is Name Address Phone Number (NAP)?
NAP is the three facts that identify a business in the physical world: what it is called, where it is and how to reach it. In local search those three facts are the fingerprint. Google and other engines match a business across the web by comparing them, so when the name, address and phone number on your website agree with the ones on your Google Business Profile, Apple Maps, Yelp, industry directories and every press mention, the engine is confident they all describe one business and credits each mention toward that business's prominence.
When they disagree (a suite number here and not there, "Inc." in one place, an old phone number in a directory nobody remembers), the engine is less sure, and a business that cannot be confidently identified ranks worse locally.
Why it matters
Why NAP matters
Because local rankings are built on trust, and consistency is how a machine measures trust. Every directory listing, citation and mention is a vote for a business's existence and location, but the vote only counts if the engine can tell it belongs to you. Inconsistent NAP splits those votes across what looks like several businesses, dilutes the signal and sometimes produces duplicate listings that compete with each other.
It also matters for customers directly. The phone number on a third-party listing is the one people call. If it is wrong, the lead goes nowhere and the review says the business never answers.
In practice
How NAP works in practice
- 01
Decide the canonical version once: the exact spelling of the name, the address formatted one way (including suite, floor and abbreviations), and the phone number with its formatting. Write it down. Put that version on the website's contact page and footer, marked up with LocalBusiness structured data, and on the Google Business Profile.
- 02
Then audit everywhere else. Search the web for your name, your phone number and your address and list every place they appear. Fix the ones you control, claim the ones you can and submit corrections to the rest. Pay attention to data aggregators, which feed many smaller directories, so correcting them fixes dozens at once. Repeat the audit after any move, rename or number change, and once a year regardless, because listings drift.
At RIOT
NAP at RIOT
We are a two-location business, with a studio in Hudson Yards in Manhattan and one in Clifton, New Jersey, so we keep two sets of NAP details straight rather than one. Two addresses means twice the places a stray suite number or an old phone number can creep in, and twice the reason to keep a single canonical version written down.
Watch out
What people get wrong about NAP
Chasing perfect formatting. Engines understand that "St." and "Street" are the same; what matters is the facts agreeing, not the punctuation. The real errors are old numbers, moved offices and duplicate listings nobody closed. The other mistake is using a tracking phone number on listings, which makes the number inconsistent across the web and sends calls through a system that may not survive the next marketing contract.
