NAP Consistency Checker

What NAP consistency is

NAP is your Name, Address and Phone number — the core facts of your business. When they’re written differently across your website, your Google Business Profile and other listings, it creates doubt: a customer wonders if they’ve got the right place, and search engines become less confident about which business is which. That uncertainty can quietly hold back your local ranking. Making every source match your Google Business Profile, exactly, is one of the simplest and most reliable local-SEO improvements you can make.

What this tool does — and doesn’t do

This checker treats your Google Business Profile as the source of truth and compares two things against it: the NAP it can read from your website, and any listings you paste in yourself. It’s honest about its scope — it does not silently “scan 50 directories,” which isn’t possible without paid data. Instead it does the part that’s genuinely useful and verifiable: catching where your own site and the listings you care about have drifted out of sync.

How the comparison works

The heart of the tool is normalization. Before comparing, it rewrites phone numbers to a single canonical format, standardizes address abbreviations (Street/St, Suite/Ste/#, North/N) and strips away punctuation, casing and legal suffixes like “LLC.” Only then does it compare, so it flags real differences — a wrong suite number, a transposed digit, an old address — rather than harmless formatting. You always see your original values; the normalization happens behind the scenes.

Fixing what you find

Start with your website, since you control it directly: make the name, address and phone match your Google Business Profile word for word, and expose them in LocalBusiness structured data so search engines read them cleanly. Then update each listing you flagged. Don’t have your Place ID yet? Grab it with the Place ID finder, and for a wider on-page review, run the local SEO audit.

Limitations

The tool can only read what your website exposes in readable markup, so a site that hides its contact details or blocks bots may not extract cleanly — paste your details manually in that case. It checks the sources you provide, not the entire web, and it’s limited to five checks a day to keep it free. It’s a focused, honest check, not a full citation audit.

Frequently asked questions

What is NAP and why does consistency matter?

NAP stands for Name, Address and Phone number. When these differ across your website, Google Business Profile and other listings, it confuses both customers and search engines — and inconsistent NAP can weaken your local ranking. Keeping every source identical to your Google Business Profile is a core local-SEO fix.

What exactly does this tool check?

It compares your website and any listings you paste against your Google Business Profile, which it treats as the source of truth. It reads your site’s LocalBusiness structured data and contact details, normalizes phone numbers and address formats, and flags where they don’t match. It does not scan dozens of directories automatically — it checks the sources you give it, honestly and precisely.

Why does it normalize the phone and address?

“Street” vs “St”, “Suite 5” vs “#5”, or a phone written five different ways are the same in reality but look different to a machine. The checker converts each to a canonical form before comparing, so it flags genuine differences rather than harmless formatting.

It couldn’t read my website — why?

For security the tool only fetches public https pages, follows a limited number of redirects and never touches private addresses. If your site blocks bots, is slow, or doesn’t expose its contact details in readable markup, extraction may fail — you can still paste your details manually to compare them.

Is the NAP checker free?

Yes — free, no signup, up to five checks a day. Everything is compared against your own Google Business Profile.
