🇬🇺How to verify a supplier in Guam
To verify a supplier in Guam, look the company up for free in the official Guam Department of Revenue and Taxation (DRT) business licence search and confirm it is registered and currently active. The registry returns no open public name search: the GovGuam DRT record view (guamtax.com Business E-Services) is login-gated and needs the company's own EIN and Gross Receipts Tax account, so an outside buyer confirms a licence by asking the DRT General Licensing Branch directly.
The official registry
- Registry
- Guam Department of Revenue and Taxation (DRT) business licence search
- Company ID
- Guam business licence number
- Cost
- Free basic lookup
- Active status
- Guam law requires a DRT business licence before a company may operate, so a current DRT licence, confirmed through the General Licensing Branch, is the baseline proof a Guam business is real and trading.
- Doing-business-as (trade) names are strictly regulated on Guam, so always verify the exact licensed legal name through DRT rather than trusting a brand or social-media name.
- New businesses clear the Business License and Permit Center (BLPC), which bundles the health (DPHSS), fire (GFD) and environmental (GEPA) approvals; a licensed food or cosmetics maker has already passed these.
- Guam charges a Gross Receipts Tax on a business's total gross income (it is paid by the business, not added at the till like a sales tax), and a Made in Guam claim is governed by local anti-misbranding consumer-protection law. Real local production is value-added: coffee roasting, chocolate, craft beverages, sea salt and Made-in-Guam food and crafts.
- For member-vetted local firms, cross-check the Guam Women's Chamber of Commerce directory (guamwomenschamber.com, 100+ SMEs) and the Guam Contractors Association directory (guamcontractors.org, about 200 firms, published as a PDF).
Before you sign: five asks no registry can answer
The register proves the company exists and who signs. It says nothing about whether the supplier survives a bad quarter, a fire or a key person leaving. Serious suppliers answer these five asks without friction; hesitation on any of them is information too.
- Business continuity: what happens to your order if their plant loses power, a strike hits or their systems go down? Ask for the plan, not a reassurance.
- Liability insurance: is product or professional liability insured, with which insurer and to what ceiling? A certificate of insurance is a one-page email for a real firm.
- Exit terms: how do you terminate if it goes wrong, what notice and fees apply, and how do you get your tooling, molds or data back?
- Support in numbers: ask for response and resolution times as figures, not adjectives. A supplier who commits to hours in writing has a support process; one who writes fast support does not.
- Named people: who exactly runs production and who owns your account? Continuity of a named team matters more than a polished sales deck, and employee-review sites often show whether that team stays.
General commercial hygiene, not legal advice.
Verify it in four steps
- 1
Open the Guam Department of Revenue and Taxation (DRT) business licence search
Guam Department of Revenue and Taxation (DRT) business licence search is the official government record of companies in Guam. Basic name or number search is free.
- 2
Search the exact legal name or ID
Search the supplier's registered name or its Guam business licence number. If the name does not match cleanly, treat it as a red flag, it may be a trade name, a different entity, or wrong.
- 3
Confirm it is active, not struck off
Guam law requires a DRT business licence before a company may operate, so a current DRT licence, confirmed through the General Licensing Branch, is the baseline proof a Guam business is real and trading.
- 4
Check it makes what it sells
A real factory carries a manufacturing activity code and a consistent trade history; a middleman reselling everything is the most common mismatch.
This is a factual pointer to public records, not legal advice. For the full method, see the 7 checks that separate a real supplier from a scam.

Questions
Is checking a Guam supplier free?
Yes. A basic name or number lookup in the Guam Department of Revenue and Taxation (DRT) business licence search is free. Some full official extracts are paid, but confirming a company exists and is active costs nothing.
What ID does a Guam company have?
Its Guam business licence number. Ask the supplier for it, then confirm it in the Guam Department of Revenue and Taxation (DRT) business licence search and check the registered name matches.
How do I know a Guam supplier is a real manufacturer, not a reseller?
The registry's activity code is the tell: a manufacturing code means a real maker, a wholesale or retail code means a trader. Doing-business-as (trade) names are strictly regulated on Guam, so always verify the exact licensed legal name through DRT rather than trusting a brand or social-media name.
