What Is NAP Consistency?
NAP consistency means your business Name, Address, and Phone number appear identically across every website, directory, and map listing. Mismatched formatting — like "St." versus "Street" — confuses local ranking algorithms and can suppress local pack visibility. Citation signals, including NAP consistency, have ranked among the top local-pack ranking factors in industry local-search ranking studies for years — consistent NAP across 50-plus citation sources remains one of the most reliable local SEO signals a business fully controls.

How to maintain NAP consistency
- Pick one canonical version of your Name, Address, and Phone number — exactly as it should appear everywhere.
- Audit your Google Business Profile first; it's the listing most other directories and algorithms cross-reference against.
- Check major directories — Bing Places, Apple Maps, Yelp, Facebook, and any category-specific platforms — against that canonical version.
- Fix mismatches at the source, in the directory listing itself, not just on your website.
- Re-check periodically. Listings drift as directories update their own formatting or a location changes hands.
Common mistakes
- Using a different phone number for call tracking on the website than what's listed on Google.
- Abbreviating inconsistently — "St." on one listing, "Street" on another.
- Leaving a closed or moved location live on secondary directories after the fact.
