Google Local Services Ads D-U-N-S Verification (July 2026): What Michigan Home Service Advertisers Must Do Before Opening a New LSA Account

On July 31, 2026, Search Engine Roundtable reported that Google has begun showing Local Services Ads advertisers a new Business Verification notice requiring a D-U-N-S number from Dun & Bradstreet. The requirement applies to “select verticals and users in the US,” and per Google’s own notice it attaches to new CIDs — accounts that already cleared verification are untouched.

That last clause is why this matters more in Michigan than the headline suggests. Google is simultaneously migrating Local Services Ads into Google Ads as a pay-per-lead Performance Max campaign type, with the first US phase starting in August 2026 for home and storefront service categories — plumbing, HVAC, electrical, appliance repair, house cleaning, lawn care, roofing, pest control, moving. Metro Detroit’s paid-lead economy runs on those nine categories.

What exactly changed in Google Local Services Ads verification on July 31, 2026?

Google added a business-registration check to LSA verification that a D-U-N-S number satisfies. Anthony Higman spotted the in-product notice and posted a screenshot to LinkedIn; Barry Schwartz wrote it up at Search Engine Roundtable on July 31. Google has published no blog post or dated rollout schedule, so treat the timing as unconfirmed even though the help-document language is live.

The notice says Google is “updating our verification process,” that new requirements appear in the Business Verification tab “for any new CIDs,” and that no action is required for CIDs already passed. The linked help document lists three fallbacks if you can’t get a D-U-N-S number: a business registration with the Secretary of State’s office, an EIN with the IRS, or a business registration with the Department of Revenue.

Why is Google checking a Dun & Bradstreet number instead of my trade license?

A license proves a person is qualified; a D-U-N-S number proves a legal entity exists at an address. LSA fraud has always exploited the gap between those two questions.

Here is the mechanism worth internalizing: the check is keyed to the CID, not to the business. A new CID gets minted by ordinary operational events — opening a second location under its own account, an agency taking over with a fresh account, an ownership change, a rebrand onto a new legal entity. Predict when a new CID appears and you can predict who gets pulled in. A Livonia roofing company that has run LSA since 2022 and changes nothing is fine. The same company standing up a separate account for a Grand Rapids branch in September is a new advertiser as far as this check is concerned, four-year billing history or not. Any restructuring around the migration produces exactly that.

Does this affect my existing Local Services Ads account?

Not today, if it is already verified and you leave it alone. Google’s notice is explicit that verified CIDs need no action.

I would not build a plan on that holding indefinitely, and this is where I part with the calmer reading circulating in the trade press. Verification exemptions get re-run when an account’s underlying facts change — a new service category, address, payment profile, or admin — and Google is mid-migration on this exact product. “No action required” describes your account’s present configuration, not a permanent grandfather clause. The asymmetry decides it: a D-U-N-S number is free, so getting one early costs a form.

What if I can’t get a D-U-N-S number — and does Michigan even have the fallback Google names?

Michigan does not have the first fallback Google lists, and this is the detail national coverage of this story keeps getting wrong. Michigan business entities are not registered with the Secretary of State.

LLCs, corporations, and limited partnerships here file with the Department of Licensing and Regulatory Affairs — LARA’s Corporations, Securities & Commercial Licensing Bureau — through the MiBusiness Registry portal. The Michigan Secretary of State handles driver licensing, vehicle registration, and elections. So when a reviewer asks a Sterling Heights electrical contractor for “Secretary of State registration,” the correct document is a LARA filing, and an owner who searches the SOS site finds nothing and concludes they have no registration. The Department of Revenue equivalent here is the Michigan Department of Treasury. The IRS EIN letter is the one fallback that reads the same in all fifty states, which is reason enough to keep a clean copy of your CP 575 on hand.

How do I tell which verification problem I actually have?

Match the symptom to the cause before you start uploading documents — most failed verifications are name-mismatch problems wearing a different costume.

• Business Verification tab shows a requirement you have never seen. You are on a new CID and inside the July 31 change. Start the D-U-N-S application now.
• Verification stalls with no stated reason. Usually a name mismatch: your LSA profile says “Warren Comfort Heating & Cooling,” your LARA filing says “WCH Services LLC,” and the registry lookup returns nothing.
• D&B says a record already exists at your address. Common for trades sharing a business park suite or registered-agent address. Claim it — a duplicate creates a second entity record that fails a later match.
• Entity shows “not in good standing.” A missed annual filing. Michigan LLCs owe an annual statement by February 15, corporations a report by May 15, both $25 and online-only through MiBusiness Registry since June 2025.
• Everything verified, leads stopped anyway. Unrelated to this change — check the migration notice and budget pacing.

How should a Michigan LSA advertiser prepare this month?

Seven steps, all executable by a three-person office in an afternoon or two.

1. Look up your entity in MiBusiness Registry and copy the exact legal name, character for character, including “LLC” and any comma. That string is what Google tries to match.
2. Compare it to your LSA profile and Google Business Profile names. If they differ, decide which is the legal name and which is the assumed name, and be ready to show the assumed-name filing.
3. Confirm good standing and file any missed annual statement first. A delinquent entity fails a registry check for reasons unrelated to Google.
4. Search D&B for an existing record at your address before applying, and claim it if it exists.
5. Apply for the free D-U-N-S number. Standard processing runs up to 30 business days; the $229 expedited option is a fee, not a requirement.
6. Assemble the fallback packet in one folder: LARA filing, IRS EIN letter, Michigan Treasury registration, trade license, insurance certificate — for every entity you operate under.
7. Export your LSA historical reports now. Past performance does not survive the move to Performance Max unless you pull it before your transition date, and you get about 14 days’ notice.

Step seven quietly costs the most. If you benchmark a fall furnace-tune-up campaign against last October’s cost per lead, that comparison leaves with the dashboard. The export-and-rebaseline sequence we run for paid media clients at Rosh Media takes twenty minutes before the email arrives and considerably longer after.

What dates belong on the calendar?

• July 31, 2026 — D-U-N-S verification notice first reported by Search Engine Roundtable. No official Google announcement to date.
• August 2026 — phase one of the LSA-to-Google Ads migration begins for US home and storefront service categories.
• ~14 days before your transition — Google’s migration email. Treat it as your export deadline, not your planning start.
• Mid-September 2026 — where a D-U-N-S application filed the first week of August lands at the 30-business-day mark, ahead of Michigan’s furnace season.
• Late 2026 — migration widens to service-area businesses without storefronts and accounts with custom bidding or booking setups.
• February 15, 2027 — Michigan LLC annual statement due; May 15, 2027 for corporations.
• 2027 — remaining categories and non-US accounts migrate.

What does this cost a Michigan service business that ignores it?

An unverified LSA account is a hard zero, not a soft decline. There is no reduced impression share to grind back — the unit does not serve.

Picture a Warren HVAC contractor opening a dedicated account for a new Rochester Hills location in late August. New CID, new requirements, no D-U-N-S number on file. Standard processing puts them in limbo into late September — the entire pre-season furnace booking window — while Southfield and Troy competitors collect every call. LSA is pay-per-lead, so the loss isn’t wasted spend; it’s revenue never quoted. At thirty tune-ups a week, a six-week outage is a five-figure hole, and the $229 expedite fee they reach for in a panic is the smallest number in that story.

Frequently asked questions

Is a D-U-N-S number free?

Yes. Dun & Bradstreet issues D-U-N-S numbers at no charge, with standard processing taking up to 30 business days. D&B also sells an expedited option — roughly $229 for delivery in about eight business days — but it is optional. Apply before you need it and the free path is sufficient.

Which Michigan document replaces “Secretary of State registration”?

Your LARA filing. Michigan LLCs and corporations register with the Department of Licensing and Regulatory Affairs through MiBusiness Registry, not the Secretary of State. Download the filed articles or a certificate of good standing and submit that when Google’s form asks for state registration.

Does this apply to Google Ads search campaigns too, or only LSA?

The July 31 notice and its help document are specific to Local Services Ads. Google Ads has run its own advertiser verification for years, where a D-U-N-S number is helpful but optional. Since LSA is being folded into Google Ads as a pay-per-lead campaign type, expect the two tracks to converge — but that is inference, not something Google has stated.

Should I delay opening a new location’s account until this settles?

Delaying doesn’t help — the requirement applies to new CIDs whenever they’re created. Get the D-U-N-S number and document packet ready first, then open the account. If you need paid visibility in a new Michigan market before verification clears, a Search campaign on the existing verified account is the bridge, a sequencing question we dig into on the Rosh Media blog.

None of this is difficult. It is paperwork that has to exist before a reviewer asks for it — and reviewers are about to start asking many Michigan trades at once.
