What Is NAP Consistency?

NAP consistency refers to keeping a business’s Name, Address, and Phone number identical across every website, directory, and platform where it appears online.

Example

If a business lists “123 Main St.” on its own website but “123 Main Street” on a directory listing, that small mismatch is a NAP inconsistency, even though a human would read them as the same address.

Why it matters

Inconsistent NAP information across the web can confuse search engines about a business’s legitimacy and correct location, weakening local search rankings, so keeping listings synchronized across directories is a core local SEO task.
