Quick answers
Why Mexico supplier verification matters
Mexico is the United States' largest trading partner and a manufacturing nearshoring leader — automotive, electronics, aerospace, medical devices, and agricultural goods. The SAT issues the RFC (tax ID) and the Constancia de Situación Fiscal; the IMPI / Registro Público de Comercio carry corporate acts. The 2014 anti-money-laundering regime (and 2022 BO regulations) require BO disclosure to SAT, but enforcement is uneven. Fraud risk concentrates in border-zone intermediaries and in suppliers offering IMMEX / maquiladora privileges without the actual programme registration.
Active fraud patterns we see in Mexico
EFOS / EDOS — invoice-mill counter-parties
Counter-party appears on SAT's lists of empresas que facturan operaciones simuladas (EFOS) or that deducted them (EDOS) — invoices may not be tax-deductible and may indicate broader fraud.
KeyBS cross-checks SAT's published EFOS / EDOS lists on every Mexican supplier.
IMMEX / maquiladora claim without registration
Supplier markets duty-free import / temporary-import privileges without an actual IMMEX programme registration with the Secretaría de Economía.
IMMEX status is verified against the Secretaría de Economía registry for any IMMEX-privilege claim.
RFC suspended (no localizado / 69-B)
RFC status is 'no localizado' or the supplier is published under SAT Article 69-B (presumed simulated operations).
Live RFC status check on the SAT portal; 69-B publication blocks the report.
Constancia de Situación Fiscal outdated or altered
PDF Constancia altered on RFC, address, or activity codes; or so old that the regimen fiscal is incorrect.
Document forensics + live SAT pull to compare against the supplier-supplied PDF.
Border-zone intermediary with no real producer link
Tijuana / Reynosa / Ciudad Juárez 'manufacturer' that is in fact a trading intermediary sub-contracting production with no quality oversight.
SAT activity codes are verified against the contracted activity; local-agent visit confirms premises (Premium).
CLABE in a personal name
CLABE provided for payment is in an individual's name rather than the RFC legal name.
Bank-beneficiary match is included from Essential upward; personal-CLABE corporate payment is blocked.

Verify my Mexico businessQuestions buyers ask about Mexico suppliers
How do I verify a Mexican supplier before payment?
Pull the RFC and Constancia de Situación Fiscal on the SAT portal to confirm status and regimen. Cross-check the EFOS / EDOS lists. Verify CLABE in the RFC legal name. For orders above USD 10k, KeyBS Trust verification combines SAT, Registro Público de Comercio, IMMEX (if claimed), sanctions, and bank-beneficiary match.
What is an RFC?
Registro Federal de Contribuyentes — Mexico's tax ID. 12 characters for legal entities, 13 for individuals. It is the canonical identifier for any Mexican counter-party.
What does EFOS / EDOS mean?
EFOS = Empresas que Facturan Operaciones Simuladas (companies SAT presumes issued simulated invoices). EDOS = those that deducted them. Exposure to either creates tax and reputational risk and is a strong fraud signal.
How long does Mexico supplier verification take with KeyBS Trust?
Standard: 2–4 business days. Enhanced (with EFOS / IMMEX cross-check): 4–6 business days. Premium with CDMX / Monterrey / Guadalajara / border-zone on-site visit: 6–9 business days.
What is IMMEX and why does it matter?
Industria Manufacturera, Maquiladora y de Servicios de Exportación — the programme that grants temporary-import duty deferral for export-oriented manufacturers. Suppliers claiming nearshoring / maquila privileges must hold a current IMMEX registration; the claim without the registration is fraudulent.
Can KeyBS check beneficial owners in Mexico?
Yes. The 2022 SAT reform requires BO disclosure. KeyBS retrieves the SAT BO declaration where available and supplements with Registro Público de Comercio shareholder data.
Should I accept CLABE in a personal name?
No. A corporate supplier must invoice and receive payment via a CLABE associated with the RFC legal name. A personal CLABE for a corporate transaction is a near-certain fraud signal.
Does KeyBS verify COFEPRIS / SENASICA registrations?
Yes — for medical, cosmetic, food, and agri-export suppliers, the category regulator (COFEPRIS, SENASICA) is verified against the relevant authority's registry.
