NAP consistency: why your name, address and phone must match everywhere

NAP consistency means your business name, address and phone number read the same way on your website, your Google Business Profile, and every directory, map and app that lists you. It matters because Google says businesses with "complete and accurate info are more likely to show up in local search results," and because customers who find a wrong number or an old address go to a competitor.

The fix is a short project with a long tail. Decide on one canonical version of your details, correct the sources that feed everyone else, merge duplicates, then check every few months.

This guide covers what Google actually says, how much weight the ranking surveys give consistency in 2026, how the data aggregators spread errors, and an audit you can run this week.

What counts as NAP (and NAP+W)

NAP stands for name, address, phone. Most local SEO teams now track NAP+W, adding the website URL, plus hours and primary category. A listing with the right phone number and the wrong website still sends customers to a dead page.

Field	Canonical rule	Common inconsistency
Name	Your real-world name, as on your sign	The short name on Google, the legal name with "PLLC" on Yelp, the name plus "Best Dentist Austin" on a directory
Address	One format, including suite number	"Ste 200" vs "#200" vs missing suite; old address after a move
Phone	One local number you control	Call tracking numbers scattered across listings; an old line that now rings someone else
Website	One URL per location	http vs https, the homepage where the location page belongs, an old domain
Hours	Current, including holidays	Hours never updated after a change

Small formatting differences ("Street" vs "St") are rarely a problem on their own. Search engines match these. The damage comes from different facts: an old address, a wrong phone number, a second name, or two listings for one place.

What Google says about consistency

Google does not publish a ranking weight for citations. What it does say, in its own documentation:

• Accuracy affects visibility. "Businesses with complete and accurate info are more likely to show up in local search results" (Google Business Profile Help).
• Your name must match the real world. "Your name should reflect your business's real-world name, as used consistently on your storefront, website, stationery, and as known to customers" (guidelines for representing your business).
• One profile per location. Google tells businesses not to "create more than one page for each location of your business, either in a single account or multiple accounts," and warns that extra profiles "can cause problems with how your information displays on Google Maps and Search" (same guidelines).
• The phone must be yours. It should connect "to your individual business location" and be "under the direct control of the business" (same guidelines).
• Prominence uses the wider web. Google says prominence is based partly on information such as "how many websites link to your business" (Google Business Profile Help).

Google builds its picture of a business from many sources. When those sources disagree, Google has to pick one, and customers see whichever version they land on.

How much NAP consistency affects rankings in 2026

The best public estimate of ranking weight is Whitespark's 2026 Local Search Ranking Factors (published November 2025): 47 local search specialists scored 187 factors. The citation factors, ranked for the local pack and Google Maps:

Factor	Rank (of 187) for local pack and Maps
HTML NAP on your website matching your Google Business Profile NAP	15
Consistency of citations on primary search engines (Google Maps, Bing Maps, Apple Maps)	28
Quality and authority of structured citations	49
Consistency of citations on key sites (Yellow Pages, Yelp, D&B, CityGrid)	63

Two things stand out. First, the top consistency factor is entirely under your control: your own website matching your own Google profile. Second, Whitespark notes the citations group lost about half a percentage point of weight from the previous edition, continuing a long decline, while three of the top five factors for AI search visibility were citation factors. The directories that matter less for Maps rank may matter more for whether ChatGPT and Gemini can find consistent facts about you.

So treat consistency as hygiene. It rarely lifts a business from position 9 to position 2 by itself. A wrong address or a duplicate profile can hold you down no matter what else you do.

Why customers care

The trust numbers are older but still the standard citation. BrightLocal's Local Citations Trust Report (March 2018, 1,025 US consumers) found:

• 80% lose trust in a local business if they see incorrect or inconsistent contact details or business names online.
• 68% would stop using a local business if they found incorrect information in online directories.
• 31% blame the business more than the directory for incorrect listings; 18% blame the directory.

Patients and customers do not separate "Google got it wrong" from "this business is disorganised." They just call the next listing.

How the data aggregators spread errors

Hundreds of directories, map apps and in-car systems do not collect business data themselves. They license it from a handful of data aggregators. An error at the aggregator level shows up everywhere downstream and can overwrite corrections you made by hand.

The main US aggregators, and where each stands in 2026:

Aggregator	Status	What to do
Data Axle	Formerly Infogroup; the company changed its name to Data Axle in September 2020 (Data Axle)	Check and correct your record; most listing tools submit to it
Foursquare	Merged with Factual in 2020, combining two former aggregators under the Foursquare name (TechCrunch)	Claim your venue; Foursquare data feeds many apps and maps
Neustar Localeze	Part of TransUnion since TransUnion completed its purchase of Neustar in December 2021 (insideARM)	Check your record if you use a listings tool that submits to it

Factual and Infogroup still appear in older guides as separate aggregators. They are now Foursquare and Data Axle.

Most businesses do not deal with aggregators directly. Listing tools (BrightLocal, Yext, Moz Local, Whitespark's citation service and others) submit your canonical data to them for a fee. If you use one, check which aggregators it submits to before you pay.

The NAP audit: step by step

Run this once properly, then as a lighter check every quarter.

1. Write your canonical NAP

Create one document with the exact name, address (with suite format), primary phone, website URL for each location, hours and primary category. Everyone who touches a listing works from this file.

2. Fix your own properties first

• Website footer and contact page show the canonical NAP as text (an image of an address is unreadable to search engines).
• Each location page shows that location's NAP and links from the Google profile.
• LocalBusiness structured data on each location page uses the same details. Google's local business structured data guide lists name and address as required and telephone and url as recommended. Test with the schema validator.
• Google Business Profile matches the website exactly.

3. Fix the primary map platforms

Google Business Profile, Apple Business Connect and Bing Places. These rank 28th in the Whitespark survey as a group and they are where most "near me" journeys start. Our Google Business Profile guide covers every field.

4. Find every other listing

Search each of these, one at a time:

1. Your business name plus city.
2. Each phone number you have ever used, in quotes ("512-555-0100" and "(512) 555-0100").
3. Each old address.
4. Your name plus each former name.

Old phone numbers are the best way to find forgotten listings, because nobody updates a directory they do not remember.

5. Correct, in priority order

Priority	Sources	Why
1	Website, Google, Apple, Bing	Highest ranking weight; most customer traffic
2	Data aggregators (Data Axle, Foursquare, Localeze)	Errors here spread to hundreds of sites
3	Yelp, Facebook, BBB, Yellow Pages, industry directories (Healthgrades, Zocdoc, Avvo, Houzz)	High-traffic sites customers actually use
4	Local chamber, city and niche directories	Smaller reach, but they often rank for your name
5	Long tail	Fix what you find; do not chase hundreds of tiny sites

Our citation building guide covers which new listings are worth creating once the existing ones are clean.

6. Record what you changed

Keep a sheet: source, URL, what was wrong, date fixed, login owner. Many directories take weeks to update, and some revert to aggregator data. The sheet tells you what to recheck.

Fixing duplicate listings

Duplicates are the most harmful inconsistency, because they split reviews and signals between two profiles and can show customers the wrong one.

Google's help page on duplicate profiles separates two cases:

• A duplicate you created and manage. You can remove it from your account. Removing a profile deletes its content and managers, so check which one holds the reviews before you remove anything.
• A duplicate on Maps you do not manage. Report it through Google Maps and ask for the two profiles to be merged. Merged profiles combine their reviews; replies to reviews may be lost.

For directories, most have a "report a duplicate" or "claim this listing" flow. When the duplicate came from an old aggregator record, fix the aggregator too, or it will come back.

Moves, rebrands and new phone numbers

These three events create most inconsistencies. When one happens:

1. Update Google, Apple and Bing on day one.
2. Update the aggregators the same week.
3. Keep the old phone number forwarding for at least a year.
4. Search the old address and old name 30 and 90 days later and fix what is left.

Call tracking without breaking NAP

Call tracking numbers are a common modern cause of mixed phone numbers. Google's guidelines ask for a number that connects to the location and is under the business's direct control, so a tracking number you own and forward can meet that rule, but every extra number is another fact to keep consistent. The safer pattern:

• Use your main local number everywhere as the canonical phone.
• Use tracking numbers on ads and on your own site through dynamic number insertion, which swaps the number only for visitors and leaves the HTML number crawlers see unchanged.
• Never submit a tracking number to a directory or aggregator.
