This free NAP checker compares your business name, address and phone number with how they appear on another listing, and flags every mismatch. Enter your official details once, paste what a directory shows, and you see right away which fields are consistent. It ignores spacing and punctuation, so it only flags differences that matter.
How to use the NAP consistency checker
- Type your official name, address and phone exactly as they appear on your Google Business Profile.
- Open a listing, like Facebook or a local directory, and copy its name, address and phone into the right column.
- Read the result. Green means consistent. Red shows both versions so you can see the problem.
- Note the fix, then clear the right column and paste the next listing.
- Log into each listing with a mismatch and correct it, or ask the site owner to.
Why NAP consistency matters
Google wants to be sure your business is real and that its details are right before it sends people to you. Its guidelines for representing your business say your name should reflect your real-world name as used on your storefront, website and stationery. They also ask for a precise address and a phone number that reaches your location.
When directories show three different phone numbers, customers call the wrong one. And search engines get mixed signals about which details are true. Clean, matching listings remove that doubt. I treat it as the floor of local SEO: it won't win rankings on its own, but messy data can hold a good profile back.
How the checker compares fields
- Name and address: lowercased, with spaces and punctuation removed. “Main St.” and “main st” match.
- Phone: digits only. “(512) 555-0100” and “512.555.0100” match.
- Not normalised on purpose: “St” vs “Street”, or “Suite 4” vs “#4”. I flag these so you pick one format and use it everywhere.
One limit: a phone with a country code (+1) and one without will show as a mismatch. That is fine. Decide which style you want and stick to it.
When to use it
- After you move, change your phone number or rebrand.
- Before a citation building push, to find what needs fixing first.
- When you take over a business or a client and don't know its history.
- When customers say they called a number that doesn't work.
Common NAP mistakes
- Old addresses left live. The new address is on Google but the old one sits on a dozen directories.
- Tracking numbers everywhere. Call tracking is useful, but use your main local number as the listed one.
- Keyword stuffing the name. “Best Dentist Austin BrightSmile” breaks Google's rules. Use your real name.
- Fixing Google only. Data spreads between sites, so stale listings can creep back. Clean the big sources too.

Once your listings match, add the same details to your site as structured data with the LocalBusiness schema generator, then score the rest of your setup with the local SEO audit.
