NAP Consistency Checker

Your business Name, Address, and Phone number (NAP) should read exactly the same everywhere it appears online. When a directory lists "123 Main Street, Suite 200" and another shows "123 Main St #200", search engines see two slightly different businesses, and that ambiguity quietly drags down your local pack rankings. This free NAP consistency checker lets you paste the NAP from every citation you control, then instantly flags the mismatches that confuse Google and frustrate customers.

To use it, paste one NAP entry per block: the business name on the first line, the full address on the second, and the phone number on the third, with a blank line between entries (the included example shows the format). The tool normalizes every field the way a search engine roughly would, lowercasing text, stripping punctuation, expanding abbreviations like St, Ave, and Suite, and reformatting phone numbers to digits, then compares each citation against the most common "canonical" version. You get a field-by-field mismatch report and an overall consistency score so you know exactly which listings to fix first.

Consistent NAP data is one of the cheapest, highest-leverage local SEO wins available, and it is foundational before you invest in reviews or links. Clean up the mismatches this tool surfaces, then track how your map rankings respond across a real geo-grid with ProMapRanker, start free to monitor your local visibility over time.

FAQ

What counts as a NAP inconsistency?

Any difference in your business name, address, or phone number across listings, even small ones like "Rd" versus "Road", a missing suite number, or a tracking phone number, counts as an inconsistency. The checker normalizes formatting differences (punctuation, casing, common abbreviations) so it focuses on real mismatches rather than harmless styling, then reports the fields that genuinely disagree.

How does the consistency score work?

The tool picks the most frequently occurring normalized value for each field as the canonical version, then measures how many of your entries match it across name, address, and phone. The score is the percentage of those field comparisons that agree with the canonical NAP. A score of 100% means every listing matches; lower scores point to citations that need editing.

Does this fix my citations automatically?

No. This is a diagnostic tool that runs entirely in your browser, nothing is uploaded or stored. It tells you which listings differ and what the recommended canonical NAP should be, so you can log in to each directory (or your listing management platform) and correct the entries yourself.
