Not all customers allow express verification. To find out whether your customer offers this service, you must log onto the CTAIMACAE platform and notice whether there is a pink envelope right beside the document you need to upload. If there is, this will indicate that the express verification service can be purchased for this document in particular.
Pay attention to the pink envelope right beside the document. If it is at the top like a title, but not beside the document, this means that the customer allows express verifications for certain documents, but not all.
