Local ranking systems cross-reference NAP data across many sources (Google Business Profile, Yelp, industry directories, the business's own website) to verify a business is legitimate and correctly located — inconsistent formatting (a missing suite number, an abbreviated 'St.' versus 'Street,' an old phone number still listed somewhere) creates ambiguity that can suppress local pack visibility, even if each individual instance is only a minor variation. Auditing NAP consistency across dozens of directories manually is impractical at scale, which is why local SEO tools typically offer bulk citation-checking features; the fix, once inconsistencies are found, is standardizing every listing to one exact, agreed-upon format and updating outdated citations (especially after a business moves or changes phone providers). This matters most for local-pack visibility specifically, less so for general organic rankings.
Example
A restaurant that relocated six months ago still shows its old address on 12 of 40 directory listings — a NAP audit catches and corrects them, resolving a local-pack ranking inconsistency between its new and old locations.
