2.5. SAT Digital Seal Certificate
Each Authorized Certification Provider (PAC) is assigned a digital seal certificate (also known as a stamp certificate) that is in the name of the SAT and in which the certifying company (in this case, Solución Factible™) is authorized to sign valid electronic invoices.
It is important to verify the validity of the PAC certificate, because if a CFDI (electronic document) is stamped with an expired certificate, the tax e-document will be invalid.
The PAC's digital seal certificate can also be used to validate the digital tax stamp. To do this, you must provide the certificate corresponding to the PAC that certified the CFDI. For your added security, Solución Factible™ offers the Digital Seal Certificate:
