When the electronic seal certificate that we have installed on the machines of the AOC Consortium expires for the use of some services that require it (eg: e-TAULER, e-NOTUM, Representa, Via Oberta- AEAT...) , you must apply for renewal through EACAT following the steps in the following FAQ: How to apply for an AOC Electronic Seal?

All you need to do is apply for the renewal of the Intermediate Level Electronic Seal issued exclusively by the AOC services and the AOC Consortium will upload the new certificate to all the services where the previous one was uploaded.

Note: In the case of Via Oberta AEAT , the registration form must be sent again with the certificate data, following the FAQ: How to renew an Electronic Seal certificate to use Via Oberta's AEAT services .
