Follow these steps:

1. Access EACAT > Procedures> AOC Consortium Provider> Digital certification service> T-CAT: Application and renewal of application certificates. The device certificate applicant must access EACAT and identify themselves with a digital certificate.

Note: You can also access a user as an editor and leave the application ready to be signed by the Device Certificate Applicant.

2. Fill in the application In the "Initial information" tab and indicate:

  • The type of certificate to request; intermediate level seal
  • The priority of the petition; ordinary or urgent (involves differences in rates and delivery time: 16 working days for ordinary requests and 4 working days for urgent ones).

3. In the "Application data" tab, indicate the "Use of the certificate" you want (in field 11):

  • The certificate will be called "Electronic Administration Services"
  • It will be used for AOC services
  • We will guard it from the AOC

  • It is used in an application specific to the entity that indirectly uses the AOC Central Signatory
  • Can only be used for the body's own tools (not AOC services)
Own direct use (no option to transfer to the AOC)
  • The applicant can decide on all aspects of the certificate and make use of delivery
  • It is used by the body's own tools in which the AOC does not need to be involved in any process.

Note: This means that the entity will not be able to download the mid-level stamp certificate from the Subscriber's Folder as the AOC Consortium will be responsible for doing so. The entity will only be able to download the public part of the certificate from the subscriber's folder.

4. Once all the details have been filled in, the application must be sent for signature using the "Send to sign" button.
