🇲🇽How to verify a supplier in Mexico
To verify a supplier in Mexico, look the company up for free in the official DENUE (INEGI) + SAT RFC validation and confirm it is registered and currently active. The registry returns DENUE confirms a real operating establishment exists at a mapped address with a SCIAN activity; SAT validates the RFC tax ID.
The official registry
- Registry
- DENUE (INEGI) + SAT RFC validation
- Company ID
- RFC (tax ID)
- Cost
- Free basic lookup
- Active status
- DENUE lists only establishments observed operating; the legal company record is in the state Registro Público de Comercio (RPC).
- For a factory, the SCIAN activity code in DENUE should be manufacturing (31-33), not wholesale/retail, the maker-vs-middleman tell.
Sector export licences
Being a registered, active company is not the same as being allowed to export a specific product. In Mexico, these sectors carry their own export licence or certificate from a named regulator, so a genuine exporter of these goods holds a current one. Ask for it, then check it at the source.

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 DENUE (INEGI) + SAT RFC validation
DENUE (INEGI) + SAT RFC validation is the official government record of companies in Mexico. Basic name or number search is free.
- 2
Search the exact legal name or ID
Search the supplier's registered name or its RFC (tax ID). 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
DENUE lists only establishments observed operating; the legal company record is in the state Registro Público de Comercio (RPC).
- 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.

Questions
Is checking a Mexico supplier free?
Yes. A basic name or number lookup in the DENUE (INEGI) + SAT RFC validation is free. Some full official extracts are paid, but confirming a company exists and is active costs nothing.
What ID does a Mexico company have?
Its RFC (tax ID). Ask the supplier for it, then confirm it in the DENUE (INEGI) + SAT RFC validation and check the registered name matches.
How do I know a Mexico 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. For a factory, the SCIAN activity code in DENUE should be manufacturing (31-33), not wholesale/retail, the maker-vs-middleman tell.
