🇲🇽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.
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.
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.
We do this check for you
On every Mexico company we list, we show what the open record says, each linked to its free public source so you can re-check it yourself, no paid badge. And we go past the big directories to the local and craft makers who are too small for them but real, then verify and sort them, so you find genuine Mexico suppliers, not just the loudest.
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.
