What NAP consistency means for a practice
NAP is shorthand for name, address and phone number. Consistency means the same three facts, written the same way, wherever the practice appears online: your website footer, your Google Business Profile, Bing and Apple Maps, insurer and association directories, review sites, and the federal NPI Registry.
It is clerical, and it still matters. Patients act on whatever listing they find first. Google builds its picture of a business partly from information across the web.2 And AI assistants repeat what they find in several places, so an old address that survives on three directories can outvote the correct one on your website. More on how assistants weigh those sources is in the guide to becoming the practice AI recommends.
What Google actually asks for
Google’s guidelines for Business Profiles are specific. The name "should reflect your business’s real-world name, as used consistently on your storefront, website, stationery, and as known to customers".1 The name field may not carry marketing taglines, phone numbers, URLs or service keywords. "Smith Chiropractic" is a name. "Smith Chiropractic, Best Back Pain Doctor Denver" is a guideline violation that can get the profile suspended.
The address must be precise and accurate, and a P.O. box is not accepted. The guidelines also ask for a local phone number rather than a central call center line whenever possible.1 Practices with several locations are told that all locations must have the same name unless the real-world signage varies.1
Google also allows public-facing practitioners, such as doctors, to have their own profiles alongside the practice.1 In a group, that makes sense only if patients book that person by name.
Why a wrong listing does more damage than a missing one
Google says local results are ranked on relevance, distance and prominence, and that prominence draws on "info like how many websites link to your business and how many reviews you have".2 Google also accepts suggested edits from the public on profiles, and reviews changes before they go live.3 So your profile is not a static record you set once. It is a record other people can propose changes to, checked against what Google finds elsewhere.
My position after cleaning up many of these: a directory listing you have never heard of, with last decade’s suite number, is worse than no listing. Absence is neutral. A conflicting fact is evidence that one of your addresses is wrong, and nothing tells a machine which one.
The NPI record most practices forget
Every HIPAA covered health care provider has a National Provider Identifier, and the practice address and phone on it live in NPPES, the federal enumeration system. Under 45 CFR 162.410, a covered provider must "communicate to the NPS any changes in its required data elements in the NPS within 30 days of the change".4 Moving suites, changing the practice phone or adding a location all count.
The record is also public. CMS publishes NPPES data through the NPI Registry, "a query-only database which is updated daily", and in a downloadable file. CMS states that the data is FOIA-disclosable and that there is no opt-out for active NPI records.5 Anyone building a provider directory can read it, which is why an address you updated everywhere except NPPES has a way of coming back.
Health coaches and nutritionists who are not HIPAA covered entities may not hold an NPI at all. For them the list below simply starts at step two.
| Listing | Who edits it | Priority |
|---|---|---|
| Practice website (footer, contact page, schema) | You, directly | First: this is the canonical copy |
| Google Business Profile | You, reviewed by Google, open to public suggestions | First |
| NPI Registry (NPPES) | You or your authorized surrogate | First, if you have an NPI |
| Bing Places for Business | You, after claiming the listing | Second |
| Apple Business (formerly Apple Business Connect) | You, after claiming the listing | Second |
| Professional association directory | You, through your membership account | Second |
| Insurer and network directories | The insurer, from your credentialing data | Third: request updates in writing |
| Review sites and data aggregators | Varies, often only by request | Third |
How to clean it up, in order
- Write the canonical version. One line each for the legal name, the public name, the street address with suite, and the main phone. Decide "Suite 200" or "Ste 200" once and never mix them.
- Make the website match it exactly, in the footer, on the contact page and in the structured data. The schema markup guide covers the last part.
- Update Google Business Profile, then check it again a week later in case a suggested edit changed something.3 The full checklist is in Google Business Profile for a health practice.
- If you have an NPI, log in to NPPES and confirm the practice location and phone. If anything changed in the last month, you are inside the 30-day window.4
- Claim the Bing Places and Apple listings. Apple has folded Business Connect into a single product called Apple Business.6 If any tool offers to import your details from Google, fix Google first, because an import copies the errors too.
- Update your professional association directory, then send written change notices to every insurer you are credentialed with.
- Search the old address and the old phone number in quotation marks. Every result that still shows them goes on a list, with the date you asked for a correction.
Who this matters most for
Practices that moved in the last five years, practices that changed their name after a partner left, and groups that added a second location all carry old data somewhere. A practice that has never moved, uses one phone number and has a tidy Google profile will get less from this work than from reviews or content. Patients who were referred to you also search your name before calling, which is covered in referred patients still search you first.
