What is NAP Consistency?
NAP stands for Name, Address, and Phone number — the three core pieces of identifying information for a local business. NAP consistency means that these three data points appear in exactly the same format across every platform where your business is listed: your website, Google Business Profile, Yelp, local directories, social media profiles, and any other citations.
Why NAP Consistency Matters for Local SEO
- Trust signal — consistent NAP confirms to Google that your business is legitimate and at the same location across all sources
- Local pack ranking factor — inconsistent NAP creates confusion; Google may suppress or lower your local ranking
- User experience — customers calling the wrong number or visiting the wrong address is a direct business problem
Common NAP Inconsistency Examples
| Issue | Example |
|---|---|
| Name variation | "Joe's Plumbing" vs "Joe's Plumbing Services" vs "Joes Plumbing" |
| Address format | "123 Main St" vs "123 Main Street" vs "123 Main St." |
| Suite variation | "Suite 4" vs "#4" vs "Ste. 4" |
| Phone format | "+1 (555) 123-4567" vs "555.123.4567" |
| Old address not updated | Previous location still listed on old directories |
How to Fix NAP Inconsistencies
- Define your canonical NAP format (decide on the exact format and stick to it)
- Use a citation audit tool (BrightLocal, Whitespark) to find all listings
- Manually update or claim listings on major directories
- Use a citation management service for bulk updates
