NAP stands for name, address and phone number, and NAP consistency simply means those three details are the same wherever your business appears online. Many SEO guides add W for website and H for hours, and it is worth checking those too.
It sounds trivial. In practice, most businesses that have been trading for a few years have at least one mismatch somewhere: an old mobile number on a directory, a previous address on Facebook, a slightly different business name on Yell. This guide explains why it matters, the mismatches we see most often in the UK, and how to audit and fix yours.
Why NAP consistency matters
Google's own guidance on local ranking talks about prominence: how well known a business is, based on information from across the web, including links, articles and directories. When your details are consistent, it is easy for any system to connect those mentions to one business. When they differ, some of that information may not be linked to you at all.
The more immediate cost is human. A customer who finds your old number on a directory and gets no answer does not try again; they ring someone else. A delivery driver or patient heading to your previous address is a bad first impression that no website can fix.
AI assistants add a new reason. When ChatGPT, Copilot or Google's AI Overviews describe a local business, they draw on multiple sources. Conflicting details make it more likely the answer is wrong or that your business is left out.
The UK mismatches we see most
| Problem | Example | Fix |
|---|---|---|
| Legal name vs trading name | 'J Smith Heating Ltd' on one site, 'Smith Heating' on another | Choose your trading name for listings; show the legal name in your website footer |
| Registered office used as trading address | Your accountant's address from Companies House appears as your location | Use your real trading address, or a service area, on listings |
| Old phone numbers | A former mobile on older directory listings | Update or remove every old listing |
| Number formats | '01392 123456' vs '+44 1392 123456' vs '01392123456' | Formatting differences are minor; the number itself must be identical |
| Address variations | 'Unit 4, Marsh Barton' vs '4 Marsh Barton Trading Estate' | Match the Royal Mail version of your address |
| Moved premises | Old address still live on Facebook and two directories | Update everything on the day you move |
| Tracking numbers | Different call tracking numbers on different listings | Use your main number on listings; track elsewhere |
Step 1: decide your master details
Before you fix anything, write down the exact version you will use everywhere. Put it in a note on your phone and a document you can share with anyone who helps you.
- Business name: your real trading name, exactly as it appears on your signage, vehicle or shopfront. No keywords.
- Address: the Royal Mail format of the address customers visit. If customers do not visit you, record that you are a service-area business and list the areas you cover.
- Phone: the main number customers should ring, in one standard format such as 01392 123456.
- Website: the full address, including whether it uses www.
- Opening hours: standard hours, plus how you will handle bank holidays.
- Short description: two or three sentences you can reuse.
Step 2: audit where you appear
- Search your business name in Google and Bing, and go through the first three pages of results.
- Search your current phone number, and every old number you have used, in quotes.
- Search your current address and any previous addresses.
- Check the big platforms directly: Google Business Profile, Bing Places, Apple Maps, Facebook, Instagram, LinkedIn, Yell, Thomson Local, Scoot, Cylex and any trade or industry directories you belong to.
- Record each listing in a spreadsheet: platform, URL, name, address, phone, website, and whether it is correct.
Step 3: fix what matters most, including moves and rebrands
Start with the sources customers and search engines use most: your website, Google Business Profile, Bing Places and Apple Maps. Then social profiles, then the main directories, then everything else.
For each directory, log in and update it if you have access. If you do not, look for a claim or edit option, which most directories offer. Where a listing is abandoned and cannot be changed, ask the directory to remove it. A missing listing is better than a wrong one.
Moving premises is the change most likely to leave a trail of wrong details behind. Update your website and Google Business Profile on the day of the move, not the week before, so customers are not sent to a building you have not opened yet. Google treats an address change as a significant edit, so expect it may ask you to verify again. Then work through Bing, Apple, social profiles and directories within the same week.
Rebranding is similar but broader, because the name changes everywhere at once. Change the real-world signage and paperwork first, then the website, then the listings. Mention the previous name on your About page for a while ('formerly Riverside Motors') so customers searching the old name still find you.
Changing phone number is the easiest to get wrong because old numbers hide in places you forget: email signatures, invoice templates, vehicle graphics, printed leaflets, old directory profiles. If you can, keep the old number diverting to the new one for at least a year while the old listings are cleaned up.
Your website is the reference point
Your own website should carry your full NAP in plain text, not only inside an image. The footer and contact page are the usual places. If you have several locations, each location page should show that location's name, address and phone.
Adding LocalBusiness structured data to your site, with the same name, address and phone, gives search engines the details in a machine-readable form. It does not replace consistency elsewhere, but it makes your website an unambiguous source.
For a single-location business, a spreadsheet and an afternoon are enough. For several locations, listing management tools can push your details to the major platforms and flag inconsistencies. They cost a monthly fee and are most useful for multi-branch businesses. Whatever you use, the big platforms (Google, Bing, Apple and Facebook) should always be checked by hand.
Keeping it consistent
- Whenever a detail changes, update your website first, then Google, Bing and Apple, then social profiles, then directories, all in the same week.
- Keep your master details note current and share it with anyone who creates listings for you.
- Repeat the search audit once a year, and after any move or number change.
- Be wary of paid services that promise to push your details to hundreds of directories. Most customers use a handful of sites; get those right first.
NAP consistency is dull, which is exactly why so many businesses neglect it and why fixing it is a quiet advantage. If you would rather hand over the audit and the ongoing upkeep, it is part of our local SEO pack at £49/month.
