RFC Verifier with SAT
Check if an RFC is active and current directly with SAT systems.
This query is made directly to the SAT portal. Results depend on SAT service availability.
Why verify an RFC?
Verifying an RFC before issuing an invoice prevents rejections and problems. SAT validates that the RFC, name and postal code match the Tax Status Certificate. An incorrect RFC is the #1 cause of CFDI 4.0 rejection.
