Quick answer: NAP stands for name, address and phone number. NAP consistency means those details are exactly the same on your website, your Google My Business listing and every directory, social profile and citation that mentions your business. Search engines use these mentions to confirm where you are and that you are a real, active business. Mismatches, such as an old address or a different phone number, can weaken your local rankings and send customers to the wrong place. Fix it by choosing one correct format, auditing where you are listed, and updating or removing every listing that differs.
Local search depends on trust. When Google decides which businesses to show in the local pack and on Maps, it looks at how confident it can be about each business’s details. Every time your business is mentioned online with the same name, address and phone number, that confidence grows. Every mismatch chips away at it. This is one of the less exciting parts of local SEO, and one of the most often neglected. If you are starting from scratch, our local SEO checklist covers the full picture.
What counts as a citation
A citation is any online mention of your business’s name, address and phone number, with or without a link. Common sources include:
- Google My Business, Bing Places and Apple Maps.
- General directories such as Yelp, Yell, Yellow Pages, Thomson Local or local equivalents in your country.
- Industry directories for your trade or profession, such as Houzz for home improvement or professional association listings.
- Data aggregators that supply business information to many other sites, which vary by country.
- Social profiles on Facebook, LinkedIn, Twitter and others.
- Local sites such as chambers of commerce, local news sites, community pages and event listings.
- Review sites relevant to your sector.
Some of these you created. Many you did not: directories often scrape or buy business data and create listings automatically.
Why inconsistent details cause problems
Search engines lose confidence
If one site lists your old address, another your new one, and a third a slightly different business name, search engines have to decide which is right. That uncertainty can weaken your local visibility, particularly in competitive areas.
Duplicate listings split your strength
Old details often lead to duplicate listings, such as two Google listings for the same business at different addresses. Reviews and signals get split between them, and one may outrank the other with outdated information.
Customers go to the wrong place
The most direct cost is practical: customers ring an old number, drive to a previous address or think you have closed. Each one is a lost job and possibly a bad review.
Common causes of NAP inconsistency
- Moving premises without updating old listings.
- Changing phone numbers, including switching to a tracking number for advertising.
- Rebranding or small name changes.
- Different people creating listings over the years, each with their own formatting.
- Automatically generated listings from data providers with old or wrong information.
- Variations in formatting, such as “Street” and “St”, “Suite 4” and “Unit 4”, or “Ltd” included in some places and not others.
Small formatting differences matter less than wrong information, but it is still best to be consistent.
Step 1: Decide on your official NAP
Write down the exact version you will use everywhere:
- Name: your real business name as customers know it and as it appears on your signage. Do not add keywords or locations that are not part of your name. Google’s guidelines are clear on this, and keyword-stuffed names can lead to listing suspensions.
- Address: formatted the way your postal service formats it, including unit numbers. Decide on abbreviations and stick to them.
- Phone number: a local number is generally better than a national or premium rate number. Use the same number everywhere. If you use call tracking for ads, keep your main number on citations.
Also note your website URL, opening hours and main business category, since these appear on many listings too.
Step 2: Fix your own website first
Your website should be the definitive source.
- Show your NAP in the footer of every page or at least on your contact page, in plain text rather than inside an image.
- Use the same format as your official NAP.
- Add LocalBusiness structured data using Schema.org markup, so search engines can read the details reliably.
- If you have several locations, give each one its own page with its own NAP. Our guide to multi-location SEO explains how to structure this.
Step 3: Update Google My Business
Google My Business is the most important listing. Check that the name, address, phone number, website, hours and categories match your official NAP exactly. If you find duplicate listings for the same location, report them through Google My Business support or the “suggest an edit” option in Maps, rather than leaving them.
Step 4: Audit your citations
Now find out where else you are listed and what each listing says.
Manual search
Search Google for your business name, your phone number and your old phone number and address. Each search can turn up listings you did not know about. Keep a spreadsheet with the site, listing URL, details shown and login information if you have it.
Citation tools
Several tools make this faster:
- Moz Local checks your listings across major directories and data providers and can push consistent details to them.
- Yext pushes your details to a large network of sites through a subscription. Listings may revert if you cancel, so understand the terms.
- BrightLocal offers citation tracking and audits, showing where you are listed and where details differ.
- Whitespark has a citation finder that helps you discover where competitors are listed and where you could be.
Step 5: Correct, merge or remove
Work through your spreadsheet, starting with the most important sites:
- Major directories and data aggregators first, since errors there spread to other sites.
- Industry-specific directories for your trade or profession.
- Local and smaller sites.
For each listing, claim it if you can and edit the details. If you cannot claim it, use the site’s correction or contact form. Request removal of duplicate listings. Note the date of each change, because some sites take weeks to update.
Step 6: Keep it consistent
NAP consistency is not a one-off job.
- Update every listing promptly whenever you move, change phone number or rename.
- Re-check your main listings every few months, since data providers can overwrite corrections.
- Keep your spreadsheet of listings and logins up to date.
- Brief anyone who creates listings or profiles for the business on the official format.
Special cases
Service area businesses
If you serve customers at their location and do not want your home address shown, Google My Business lets you hide your address and set a service area. Keep the address consistent in the background anyway, and check how other directories handle hidden addresses.
Virtual offices
Using a virtual office address purely to appear in a different area is against Google’s guidelines and can lead to suspension. Only list addresses where you genuinely operate and meet customers or have staff.
Call tracking numbers
Use tracking numbers in ads and on specific landing pages, but keep your main number on citations and in your Google listing’s primary number field.
FAQ
Do small differences like “St” and “Street” matter?
Search engines are fairly good at recognising these as the same, but consistency is still best. Wrong addresses and phone numbers matter far more.
How long until fixes show up?
Google My Business changes usually appear within days. Directory updates can take weeks, and search engines may take longer to notice them.
Do I need a paid tool?
Not for a single location with a modest number of listings. A spreadsheet and some patience work. Tools save time for multiple locations or a messy history.
