If you run Local Services Ads for a home or storefront business, you may have seen a new message from Google lately asking for something called a D-U-N-S number. Search Engine Roundtable was first to flag it, reporting that Google has begun alerting advertisers that a D-U-N-S number will soon be required to verify some businesses and users in the United States.

The reaction was predictable. Half the people who saw it assumed it was a phishing attempt. The other half assumed it was another fee. It is neither. But it is a real change, it lands on a real deadline, and if you ignore it long enough it can take your ads offline. Here is the plain version.

What a D-U-N-S Number Actually Is

A D-U-N-S number is a unique nine digit identifier assigned to a business by Dun & Bradstreet, a company that has been in the business credit and business identity game for a very long time. Think of it as a social security number for your company, except it is public and it is used to confirm that your business is a real, distinct entity rather than a name someone typed into a form.

It is globally recognized, it is free to get, and plenty of businesses already have one without realizing it. Government contractors, companies that have applied for business credit, and anyone who has published an app through certain developer programs have usually been issued one at some point.

Google is not inventing anything here. It already partners with Dun & Bradstreet to confirm the details you enter during advertiser verification. What is changing is that for a growing slice of Local Services advertisers, the D-U-N-S number is moving from optional supporting evidence to a required piece of the check.

Why Google Is Doing This

Local Services Ads sit at the top of Google's search results with a Google Guaranteed or Google Screened badge attached. That badge is a promise to the searcher that the business has been vetted. The entire value of the format depends on people trusting that the plumber they are about to call is a licensed, insured, real plumber and not a lead reseller wearing a costume.

The weak point in that promise has always been verification. Fake and duplicate listings, businesses operating under borrowed identities, and lead farms have all been persistent problems in the home services space. Tying accounts to a hard business identifier like a D-U-N-S number makes it much harder to spin up a fake local business, and much easier for Google to catch one that tries.

So while the extra step is annoying, the intent is the kind of thing that actually helps legitimate operators. Every fake listing that gets filtered out is a competitor that is not sitting above you on a lie.

Who Is Affected First

This is not a universal switch flipped for everyone at once. Google is rolling it out to select verticals and users, starting around August 2026, and expanding from there.

The early group is heavily weighted toward home and storefront services in the US. That includes categories like plumbing, HVAC, electrical, appliance repair, house cleaning, lawn care, roofing, pest control, and moving. If you operate in one of those trades and run Local Services Ads, you are near the front of the line and should assume this is coming to your account.

The important nuance, and the part that keeps most people from needing to panic, is how the requirement gets applied. New requirements appear in the Business Verification tab of your account, and they generally attach to new accounts or accounts that still need to complete verification. If your account has already passed its verification checks, Google's guidance is that no action is required for it right now. In other words, the businesses most exposed are the ones setting up fresh or the ones that never fully cleared verification in the first place.

How to Get a D-U-N-S Number

The process is straightforward, and it is free. You do not need to pay anyone to do it for you, and you should be suspicious of anyone who offers to sell you a "D-U-N-S registration service" for a fee.

  1. Go to the Dun & Bradstreet enrollment site and select your business type.
  2. Fill out the registration form. You will need your legal business name, address, phone number, the owner's name, your legal structure, your industry, and your employee count. Use the exact details that match how your business is registered, because mismatches are what cause verification to fail later.
  3. Submit the application.
  4. A Dun & Bradstreet representative may contact you by phone or email to confirm details.
  5. Once it is processed, they email you your nine digit D-U-N-S number.

The one thing to respect here is the clock. Standard processing can take up to 30 days. There is usually a paid expedited option if you are in a hurry, but the smart move is simply to not be in a hurry. Start now, while your ads are running fine, so the number is sitting in your inbox before Google ever asks for it.

The Mistake That Takes Your Ads Offline

Here is the part that matters more than the paperwork itself.

Local Services Ads do not degrade gracefully. Unlike a regular search campaign that just keeps spending, an LSA account that is not verified loses its badge and stops showing. There is no partial credit. If Google adds a D-U-N-S requirement to your verification, and you let that requirement sit unmet, your listing can go dark right at the moment a customer is searching for exactly what you sell.

Now stack that against a number that takes up to 30 days to issue. You can see the trap. The businesses that get hurt by this will not be the ones who found it hard. They will be the ones who saw the notice, decided it looked like spam or that they would deal with it later, and then discovered the deadline was real about two weeks after their ads quietly stopped.

So the entire game here is timing. Check your account, get the number early, and enter it before anything is forced.

What to Do This Week

You do not need a project plan for this. You need about thirty minutes.

  1. Log into your Local Services Ads account and open the Business Verification tab. If a D-U-N-S requirement is there, it will say so. If it is not, you are not on the current wave, but keep reading if you are in one of the affected trades.
  2. Check whether you already have a D-U-N-S number. Dun & Bradstreet has a free lookup tool. Many established businesses are already in the system and can skip the wait entirely.
  3. If you do not have one, apply now. It is free, it takes a few minutes to submit, and starting today means the 30 day window works for you instead of against you.
  4. Make your details match everywhere. The name, address, and legal structure you give Dun & Bradstreet should match your Google Business Profile, your license, and your LSA account. Consistency is what makes verification pass on the first try.

That is genuinely the whole task. It is not complicated. It is just one of those things that is easy to do early and painful to do late.

How This Fits the Bigger LSA Picture

The D-U-N-S requirement is not happening in a vacuum. Google is in the middle of folding Local Services Ads into the main Google Ads platform, retiring the standalone LSA dashboard, and moving lead generation toward Performance Max campaigns with pay per lead goals. Verification is getting stricter in the same window that the entire product is being rebuilt.

None of that should scare you off Local Services Ads. For a lot of home and local businesses, it is still one of the highest intent, lowest waste channels available. You are paying for leads from people actively searching for your service in your area, with a trust badge attached. That is hard to beat. But it does mean the platform is asking for more housekeeping than it used to, and the accounts that stay on top of the housekeeping are the ones that keep the badge.

If you would rather not track all of this yourself, that is a fair thing to hand off. We keep an eye on verification requirements, migration deadlines, and the badge status for the accounts we manage, so a change like this becomes a five minute heads up email instead of a listing that vanishes right before your busy season.

The requirement is real, it is manageable, and the only version of this that goes badly is the one where nobody dealt with it in time.
