CASIA FAQs

No, CASIA can only be used to communicate  procedures, queries or incidents related to matters within the scope of management of the Social Security General Treasury.

For INSS matters, you should contact the"Call Centre".

The Social Security General Treasury processor handling your case will be able to modify certain aspects of the classification you have made, e.g. the subject, category or subcategory of your queries or errors/incidents without the need for you to take any further action.

However, if an enquiry or an error/incident involves an administrative action, you will need to open the appropriate Request for Action.

You will receive an e-mail informing you that the Social Security General Treasury has resolved the procedure or  has requested more information on the matter, as long as the main user of the authorisation has communicated the e-mail address through the Consultation and Modification of Contact Details Service of the RED system's virtual office.

You will also receive an email notifying you of the resolution of those queries made through the Helpline that could not be resolved in the first call.

The response given to the case can be consulted through the Case Management functionality. 

Yes, the Authorised person can request the Social Security Number through CASIA of those workers for whom they are subsequently going to communicate their registration. To do so, you must use the corresponding procedure accompanied by Form TA.1 signed by the worker, DNI or NIE and, if applicable, certificate of disability status. 

Procedures that cannot be requested through CASIA must be submitted through the Electronic Register.

The procedures that can be submitted through CASIA will be progressively updated.

Those requests for administrative actions as long as they cannot be managed through the services of the RED System and/or SEDESS, because the functionality does not exist or because the regulatory period established for its use has been exceeded.

When a procedure is registered, a Proof of Opening of Procedure will be generated, stating the date and time at which the application was made.

Technical cases are queries relating to  the installation of software, technical requirements for the transmission of files or communications, as well as errors or incidents related to the software or hardware of the Authorised RED. In short, those cases whose resolution may require the help of an IT specialist, in relation to the use of the RED System.

For example: Problems with electronic certificates, the installation or updating of RED System software,  connecting to the RED System, problems in communications (sending, downloading messages) between the authorised person and the RED System.

The creation of a technical case requires the completion of the "Technical Data Form" located in theErrores- Incidencias Materia Técnica" section of the website.

All cases in which an error is reported as a result of an improper operation of the system or incorrect action by the user.

This includes all errors or incidents that occur when the authorised person carries out any procedure online or in the SEDESS, in the transmission of files through the RED System, or in the responses received through these means.

All cases classified as errors or incidents in the TGSS manuals should be recorded this way. For example, those set out in the document "Direct Settlement System. Error Handling".

Important: If an administrative procedure is necessary to resolve the error, the case must be registered as such. In the event that it has been incorrectly classified as an error/incidence, it will be closed and the need to open the appropriate Request for Action will be reported, as this case requires a different processing procedure.

Through CASIA you can submit queries, errors or incidents arising in the transmission of files through the RED or SLD System or in the functionalities of the Online Services and submit applications for procedures within the scope of management of the Social Security General Treasury that cannot be carried out through the RED System and/or SEDESS.

A query is a request for information on issues related to Affiliation, Contribution, RED System, SLD or RED Direct procedures, e-Office or Authorisation Management, among others.
