How do I check a supplier in Mexico?

Ask the supplier for its RFC, the tax ID, and read it against the official lists. Testigo holds 7 lists for Mexico that are read by RFC: SAT artículo 69-B (SAT, 2026-08-31, 11,241); SAT artículo 69-B Bis (SAT, 2026-09-23, 3); SAT artículo 69: no localizados (SAT, 2026-07-01, 14,059), and 4 more. Mexico's plant registry, DENUE, carries no RFC, so the lists are read with the RFC you enter, not from the plant record. Each list shows its publisher and edition date. An empty result is not a clean bill of health: it covers those lists and editions only.
