What Is NAP in Local SEO? Name, Address and Phone Consistency
NAP stands for name, address and phone number. Local search tools and AI assistants compare these details across your website, Google Business Profile and directories, and differences can send mixed signals about who and where you are. Use identical wording everywhere, record the master version in one document, and fix differences when you find them.

What NAP means
NAP is shorthand for the three details that identify a local business: its name, its address and its phone number. A mention of those details on another site is called a citation. Citations are not links; they are references that other sites can use to confirm your business exists.
Why it matters
UK local SEO guides say Google reads citation sites when deciding which business to show for a local search, so consistent details help it be confident about yours. The same details are read by AI tools, which agencies say get confused when a business name, address or description varies between sites. Customers care too: a 2023 BrightLocal report, as cited by one UK summary, found that 62% of consumers would avoid a business if they found incorrect information about it online.
The differences that cause problems
| Difference | Example |
|---|---|
| Company suffix | Ltd on one site, Limited on another |
| Abbreviations | Road and Rd, Street and St |
| Unit or suite | Unit 4 on one site, Suite 4 on another |
| Phone format | 01234 567890 and +44 1234 567890 |
| Punctuation and and | Smith and Sons, Smith & Sons, Smith and Son’s |
| An old address | The previous premises still on a directory |
| A tracking number | A call tracking number instead of your main number |

Set your master NAP
- Write your business name exactly as on your signage and paperwork.
- Write your address in full, once, in the format you will always use.
- Choose one main phone number and its format.
- Save these three lines in one document, and add your website address.
- Use that wording whenever you create or update a listing.
Where to check
- Your website header, footer and contact page.
- Your Google Business Profile, Apple Business Connect and Bing Places listings.
- The directories you use. See the best UK business directories.
- Social profiles, such as Facebook and LinkedIn.
- Any old listing from a previous address or owner.
The NAP consistency checker compares what you paste against your master details.
How to fix differences
- Log in to the listing, or claim it if you have not.
- Change the details to match your master version.
- Remove duplicates rather than leaving them. See how to find and remove a duplicate Google listing.
- If you use a call tracking number, keep your main number as the primary one on listings and follow the tracking provider’s guidance.
- Check again in a few weeks.

Frequently asked questions

Do small differences really matter?
Guides say consistency helps search engines and customers trust the details. Formatting differences are minor, while wrong details are more serious. Aim for identical wording.
What is a citation?
A mention of your business name, address and phone number on another site, such as a directory. It does not have to link to you.

Whenever you move, change number or name, and at least twice a year otherwise.
