Also goes by Name, Address, Phone consistency, NAP+W [![Siite](/images/layout/logo.svg)Written by Siite](/about/)Updated September 8, 2026 ## Entry contents [All Terms A to Z←Browse the full dictionary](/dictionary/) NAP stands for name, address and phone number. Consistency means those three details appear in exactly the same form on your website, on your [Google Business Profile](/dictionary/google-business-profile/), and on every directory, chamber page and supplier listing that mentions you. Some people add a W for the website address. It sounds like bookkeeping, and it is, but it quietly decides how confident Google is that all those mentions describe one business. > **Briefly explained** > > - Your name, address and phone, written identically everywhere. > - Google matches mentions to businesses. Mismatches weaken the match. > - The damage shows up as unstable rankings nobody can explain. > - It breaks every time you move, rebrand or change a number. ## What exactly has to match? The rules are not equally strict across the three fields. - **Name:** What you trade under. Not the name with a city or a service added, and not a shortened version on some listings and the legal entity on others. - **Address:** One format, including the suite or unit. If you do not serve customers at an address, see [service area business](/dictionary/service-area-business/). - **Phone:** One primary number that stays the same everywhere a search engine can read it. Formatting differences — “St” against “Street”, a dash in the phone number — are generally tolerated. Substantive differences are not. ## Why does a mismatch cost rankings? Because Google builds its picture of a business by matching mentions across the web. When one listing says the business is at Suite 4 with one number, and another gives no suite and an old cell, the system has to decide whether those are the same company. Every doubt makes the match weaker. A weak match rarely produces a dramatic drop. It produces something more frustrating: a position that moves around for no visible reason, while a competitor with duller content sits still above you. ## Where do the mismatches come from? Almost never from carelessness. They accumulate. - A move, with the old address still live on a dozen sites - A rebrand, applied to the website and nothing else - A call tracking number published in a directory - A supplier or franchise directory filled in years ago by someone else - A listing auto-created from public records, which nobody claimed ## How do you clean it up? 1. Decide the canonical format. Exact trading name, suite number, one primary number. Write it down where the next person can find it. 1. Audit where you are already listed, including what you never created. Search your number and your old addresses in quotes. 1. Correct the high-authority sources first: Google, Apple Business Connect, Bing Places, the big data aggregators, then the platforms your customers use. 1. Replace published tracking numbers with dynamic number insertion on your own site, so the public number never changes. 1. Keep the list. The next change will be easier than this one was. ## What do the terms mean? - **NAP:** Name, address, phone. NAP+W adds the website address. - **Canonical format:** The one version of your details that every listing should copy. - **Data aggregator:** A company that feeds business records to many smaller directories, which is why one bad record reappears after you fix it. - **Dynamic number insertion:** Script that swaps the displayed number on your own site for tracking, while leaving the published number alone. - **Duplicate listing:** Two records for one business on one platform. They split reviews and signals. ## What should you check each quarter? Fifteen minutes, four times a year. - The number on your profile still rings where you expect - The address matches what is on your invoices - No new duplicate has appeared on the big platforms - Suggested edits that Google or the public applied without telling you - The listing on any supplier or association site you joined since last time Owner questions ## What owners ask us about NAP Consistency ### Does a suite number or an abbreviation really matter? +Minor formatting differences are usually tolerated. The problems are the substantive ones: a different phone number, an old address, or a name that no longer matches the sign on the door. ### Can I use a call tracking number in directories? +Use dynamic number insertion on your own website instead, so the number search engines see stays constant. Publishing a different tracking number in every directory is what breaks the match. ### How do I find listings I never created? +Search your phone number and your old addresses in quotes, check the big data aggregators, and look at supplier and association directories. Most businesses are listed in places nobody there ever set up. ### What do I do about an old address I can no longer access? +Claim the listing through the platform's recovery process, or report it as closed or moved. Leaving it live splits your signals and sends customers to a place you left. ### How often should this be checked? +Once a quarter is enough once it is clean, and immediately after a move, a rebrand or a new phone number. Those three events are what break it.Put this to work ## Guides that use this Step-by-step playbooks from the team, written for owners doing the work themselves. No sign-up and no email required.
