CSD (digital seal certificate)
The certificate SAT issues to seal your invoices. It is used only to issue CFDI and proves that you issued them.
To issue CFDI you need a digital seal certificate (certificado de sello digital, CSD) from SAT. With it, every invoice you issue carries your digital seal, which proves you issued it.
The essentials
- It is used only to issue tax receipts; it doesn’t replace the e.firma elsewhere.
- You can have one for all your locations or one per location.
- It can only be requested through an electronic form signed with your e.firma.
When SAT restricts it
The Tax Code lets SAT temporarily restrict a CSD in certain cases before revoking it (art. 17-H Bis). Without a CSD you can’t invoice, so it pays to deal early with what puts it at risk, such as suppliers on the 69-B list left uncorrected.
