Certificate Registration

In order to send the TicketBAI Files to the Tax Authorities using a Device Certificate, the certificate has to be associated to the VAT Number (NIF) of the taxpayer who is issuing the invoices. This is a simple process done within the corresponding Tax Authority's website:

In order to perform this registration, either fiskaly or the POS Vendor will provide the Device Certificate's Number.


The taxpayer does not have to provide their own private digital certificate, but will have to use it to log in to the Tax Authority's website. This registration is the only required step to be performed on behalf of the taxpayer.


The VAT Number (NIF) indicated must be associated with the Device Certificate used. If the taxpayer fails to inform the Device Certificate’s number to the Tax Authority, the mandatory sending of TicketBAI Files will result in rejection.
