Summary
NAP stands for Name, Address and Phone number: the three pieces of business information that must be identical everywhere a local business appears online.

NAP stands for Name, Address and Phone number. In local SEO, it refers to the core identity of a business as it appears on its website, its Google Business Profile, directories, social networks and review sites. Some practitioners use NAPW (adding the website URL) or NAP+ (adding hours and categories), but the principle is the same: one business, one set of details, repeated identically everywhere.
Consistency matters because search engines and the AIs cross-check sources to decide whether information about a business is reliable. When the name, address or phone number differs from one site to another, they are less confident about which version is right, and the business can lose visibility in local results.
The name is the real-world business name, exactly as it appears on the storefront, invoices and signage. The address is the full postal address in a consistent format (same street abbreviation, same suite number). The phone number is the main local number, ideally the same one everywhere, rather than a different tracking number on each platform.
Each mention of these details on another website is a local citation. Citations with complete and identical NAP data act as votes of confidence: they confirm that the business exists, where it is and how to reach it.
Google states that local results are ranked on relevance, distance and prominence. Prominence is partly built from information found across the web about a business, including directories and articles. Consistent NAP data makes it easier for Google to connect those mentions to the right Google Business Profile and to trust its address and phone number.
Inconsistencies create the opposite effect: duplicate listings, mixed reviews between two profiles, customers calling an old number or driving to a former address. They also confuse the data aggregators that feed maps, GPS systems and voice assistants, which can then spread the wrong information further.
On your own website, show the NAP in a crawlable text format (not only in an image), usually in the footer and on a contact or location page. For multi-location businesses, create one page per location with its own NAP and an embedded map. Adding LocalBusiness structured data repeats the same details in a machine-readable format.
Off your site, the priority platforms are Google Business Profile, Apple Business Connect, Bing Places, the main national directories, industry-specific directories, and social profiles such as Facebook and LinkedIn. Quality and accuracy of a few strong listings matter more than the number of directories.
Start by writing down the reference version of your NAP, character by character. Then search for your business name, your phone number and your former addresses on Google to list every platform that mentions you. Note each variation: old address after a move, call tracking number, different spelling of the name, missing suite number.
Fix the most visible listings first: Google Business Profile, your website, Apple and Bing, then the main directories. Claim the listings you can edit, request corrections where you cannot, and merge or remove duplicates. After a move or a rebrand, update everything in one go and keep a list of all accounts for the next change.
The most common mistake is using a different tracking number on each platform without keeping the main number visible. Another is adding keywords or city names to the business name ("Smith Plumbing Best Plumber Boston"), which breaks Google's guidelines. A third is forgetting old directories after a move, so the previous address keeps circulating for years.
Small formatting differences ("Street" versus "St.") are generally understood by Google and are not a priority. Focus on real conflicts: different phone numbers, different addresses, and different names.
For local SEO, consistent NAP data supports eligibility and ranking in the local pack, reduces duplicate profiles and protects reviews. It is one of the simplest technical foundations of local visibility, and one of the cheapest to fix.
For GEO, consistency matters even more. When an assistant like ChatGPT, Gemini or Perplexity recommends a local business, it combines data from profiles, directories, review platforms and the business website. If these sources agree, the business is easier to identify and recommend; if they conflict, the answer may show an old address or skip the business. Sorank's AI mention tracking helps you check how the AIs describe your brand.
NAP, for Name, Address and Phone number, is the identity card of a local business online. Keeping it identical on your website, your Google Business Profile and the directories that matter helps Google trust your listing, improves your chances in the local pack and gives the AIs a clear, consistent picture of your business.

Yes. Google uses information found across the web to assess the prominence of a business, and the AIs cross-check profiles, directories and websites before recommending a local business. Conflicting addresses or phone numbers reduce trust in both cases.
You can, but keep your main local number as the primary number on your website and Google Business Profile, and add tracking numbers as secondary numbers where the platform allows it. Using a different number everywhere breaks consistency.
