Timbre Fiscal Digital

Certification complement of the Mexican CFDI (SAT).

Definition

The cfdi:Complemento/tfd:TimbreFiscalDigital node is added at certification. Its required attributes are UUID (fiscal folio), FechaTimbrado (timestamp in Mexico Central time), SelloCFD (issuer seal), RfcProvCertif (PAC's RFC), NoCertificadoSAT and SelloSAT (the SAT digital seal). Without a valid TFD a CFDI has no fiscal validity.

Origin

Standard published by the SAT (Servicio de Administración Tributaria): the TimbreFiscalDigitalv11.xsd schema, part of Anexo 20 of the Resolución Miscelánea Fiscal. The UUID follows IETF RFC 4122.
