What NAP Consistency Actually Means
NAP consistency means your business Name, Address, and Phone number are identical — not just similar — across every platform that lists your business: your website, Google Business Profile, Yelp, Yell, Checkatrade, Facebook, Apple Maps, Bing Places, and dozens of other data sources Google uses to verify your existence.
Identical means precisely the same. "Will's Roofing" and "Wills Roofing" are different. "020 7946 0000" and "+44 20 7946 0000" are different. "14 High Street" and "14 High St" are different. To a human they look the same — to Google's data crawlers, they create ambiguity about whether these listings refer to the same business.
Why It Matters for Google Maps Rankings
Local search ranking relies heavily on Google's confidence that your business is exactly what you say it is, located exactly where you say it is. Consistent NAP data across multiple authoritative sources functions as corroborating evidence — multiple sources saying the same thing increases Google's trust.
When NAP is inconsistent, Google faces a signal conflict. If your Yelp listing says you're at 14 High Street and your Yell listing says 14 High St, Google now has two conflicting data points about the same business. The resolution is simple: it trusts you slightly less — and that manifests as a slightly lower ranking position.
At scale, with dozens of inconsistent citations, this trust deficit becomes significant.

How to Audit Your Own NAP
The fastest way to audit your NAP is to search Google for your exact phone number (in quotes) and your exact business name. Look through the results on the first 3–4 pages and note every listing that appears. For each one, check whether the name, address, and phone match your GBP exactly.
Key platforms to check:
- Google Business Profile (this is your master reference)
- Bing Places for Business
- Apple Maps (via Apple Maps Connect)
- Yelp UK
- Yell.com
- Checkatrade / TrustATrader (if you're a tradesperson)
- Facebook Business Page
- Thomson Local
- FreeIndex
- Scoot
- Your own website — footer and contact page
How to Fix NAP Inconsistencies
Start by deciding on your canonical NAP — the exact version you'll use everywhere. Write it down:
- Business name — exactly as registered, including Ltd/Limited, punctuation
- Address — full postcode, no abbreviations
- Phone — one format, consistently formatted
Then work through every listing you found during your audit and update each one to match. Most directory platforms have a claim/edit function. Some (like Apple Maps and Bing Places) require ownership verification before you can edit.
Warning: Some data aggregators automatically push your business data to dozens of smaller directories. If you update Yelp and Yell but not the underlying data aggregators (Neustar Localeze, Foursquare, etc.), the corrected data may be overwritten again within weeks. For lasting fixes, target the aggregators as well as the individual directories.
Building New Citations the Right Way
Once your existing NAP is consistent, every new citation you build amplifies your local authority. A citation is any online mention of your business NAP — even without a link.
For UK businesses, the highest-value citation sources are:
- Companies House (automatically listed when registered)
- Yell, Thomson Local, FreeIndex
- Trade-specific directories (Checkatrade, Gas Safe Register, NICEIC, CHAS)
- Local Chamber of Commerce directory
- Industry association member listings
- Local newspaper "business directory" sections
Always use your exact canonical NAP when submitting to any new directory. Create a simple document with your canonical NAP that you copy from every time — never type it from memory.
NAP inconsistencies are hard to find and tedious to fix.
