This service lets you request changes, via the Electronic Registry, to the details of a company signed up to any of the Social Security Regimes, with the exception of changes to the management body and/or collaborating body.

About this procedure

Who it is for

Companies that have to report changes to contribution account code details.

What you can do

  • Submit an Electronic Register application.
  • Download and attach an application form.
  • Attach documentation.

What you need to do this

  • Complete and attach application form TA.7 (In the case of the Special System for Domestic Employees, the TA.6-0138_HOGAR form).
  • Attach all documents listed in the instructions on the form. When necessary, documentation will be provided that shows evidence of the changes.
  • Have software that enables you to fill in and save the application form to be attached.

Please note

If you are logging in with a Username + Password (permanent Cl@ve), in order to guarantee a higher level of security, you will be sent a code via SMS to the mobile number that you provided at the time of registration. You must enter this code in order to sign the communication in the electronic register.

The total size of the documents to be attached must not exceed 10 Mb.

Next steps

Once the process has been completed, you will receive a “proof of receipt” in PDF format.

If you do not receive the confirmation message, or if you receive an error or failed sending message, you should resubmit the application at another time or use other channels.

In general, the resolution of the application is communicated by post with proof of receipt.

You can get more information regarding your application via telephone or in person at the Regional Office or Administration of the Social Security General Treasury.
