The following alternative Social Security channels are available:

• For the filing of applications and other documentation, the Services are available in the Social Security Electronic Office or in Your Social Security  (you need to have a digital certificate or a  Cl@ve username).
  
  
• You can also use the electronic channel offered by the Acceso al Sistema RED.
  
  
• For all other communications, the Submission of documents, applications and communications in the Electronic Registry Service is available,  which can be accessed with a digital certificate or a Cl@ve username. However, access has been temporarily enabled without the need for a certificate for the submission of applications or documentation in urgent and essential cases, before the INSS, the TGSS and the ISM.
  
  
• Telephone information service. If concerning another type of urgent and essential information or action, you can contact the following numbers:
  • The Spanish National Social Security Institute (INSS): 901 16 65 65, available from 9:00 to 20:00 Monday to Friday, not including public holidays.
  • The Social Security General Treasury (TGSS): 901 50 20 50, from 8:30 to 18:30 Monday to Friday, not including public holidays.

A family member, next of kin or a professional who does have a digital certificate or a Cl@ve username may represent you, therefore enabling you to use our electronic services. You must include a signed copy of the standard representation model found in the accompanying documentation for the corresponding electronic service in your application.

If you need to know your Social Security Number (NUSS) access the “Duplicate membership document” service. In the event you do not have it you can find it via this service.
Up until now, electronic Social Security services that allow access with SMS authentication, primarily for accessing reports, required the introduction of information relating to your Social Security Number. In order to facilitate the user's use of electronic services the requirement to report this information has been eliminated, maintaining identity verification with simple information, DNI or NIE and date of birth, in addition to the introduction of a code sent to the mobile phone number that you provided to Social Security.
