It is crucial to keep your personal information up to date. That’s why we will show you how to change your Social Security telephone number online, step by step.

In Social Security, as in other administrations, it is essential to keep all your personal information up to date. We explain how to change your Social Security telephone number online, at their offices, or by phone.

Why is it important to update your Social Security data?

When you change your address, it is essential to notify Social Security, because if they have to send you an official written notification and they do it to your old address, you would not be aware of it.

The same applies to a cellphone number. If you have activated the option to receive notifications by SMS (for example, to know when a company enrolls or suspends you from Social Security), you will miss these notifications if the number is not updated. You will also be unable to do certain online procedures in which a confirmation SMS is sent to your cellphone, for example, to request an online employment history. In these cases, if the telephone number is incorrect and you have no other form of identification, you will not be able to carry out your procedure.

How to change your Social Security phone number via INTERNET

If you have a digital certificate, electronic DNI, or user and password of the [email protected] System, you will be able to see the data that Social Security has about you at any given time.

To do this, you must access the Social Security electronic headquarters and click on the option “Change of address” or “Communication of telephone and e-mail”, depending on the case.

Please note that when you modify your telephone number you can tick a checkbox to receive communications from the Social Security General Treasury by SMS and that you can also change your address and telephone number from the “Tu Seguridad Social” page, and then consult your data at any moment.

How to apply for a change of phone number by written request

If you do not have any identification means such as a digital certificate or [email protected], another option is through the “Presentation of other Writings, Applications and Communications”. For this you must follow the steps below:

  1. Enter the Electronic Headquarters of the Social Security.
  2. Fill in the form with the data of the applicant.
  3. Indicate the category “Citizen / Worker”.
  4. The procedure “Communication and variation of contact data”.
  5. Explain the reason for your letter, request, or communication.
  6. Attach the DNI / NIE on both sides.
  7. Attach Form TA-1 properly filled in and signed. You can download it here.

How to request the rectification of your Social Security data at their OFFICE
