NAP Checker — Verify Business Name, Address & Phone Consistency

NAP consistency — the same business Name, Address, and Phone number everywhere — is a basic local SEO trust signal. One “St.” here, one old phone number there, and search engines (and customers) start doubting which listing is right. Enter your canonical details once, paste your directory listings separated by blank lines, and this checker normalizes spelling, abbreviations, and phone formats, then flags every mismatch field by field. Everything runs in your browser; nothing is sent anywhere.

How it works

Type your one canonical name, address, phone number, and website, then paste each directory listing as its own block separated by a blank line. The checker normalizes everything first — “St.” and “Street” count as the same, punctuation is ignored, and phone numbers are compared by digits only — then reports each field as a match or a mismatch per listing. Download the CSV report to hand to whoever fixes the listings.

Everyday uses

• New business launches — confirm every directory went live with the right details.
• Moves and rebrands — find the listings still showing the old address or number.
• Agency audits — run a client’s whole listing set through one check.
• Franchise checks — verify each location’s listings separately.
• Quarterly hygiene — re-run the check every few months to catch drift early.
