Preliminary information

Changing the telephone number associated with SPID, as you will find out shortly, is an operation that is anything but complicated, as long as you remember the login credentials of the account on which to intervene and that you have activated the second factor of access via SMS or proprietary app (which is usually requested immediately after the credentials are issued, to make them operational). In any case, if you need to recover the SPID credentials because you no longer remember them, you can refer to the tutorial I dedicated to the topic.

Before proceeding, however, I must underline an important detail of the matter: some certifying bodies could prevent the modification of the telephone number independently and require the intervention of a human operator as a security measure to protect the person and the data connected to him. The mobile number, in fact, is used for sending communications and OTP codes for SPID level 2 access and represents a fundamental detail of the SPID identity.

In some cases, it is not possible to receive operator assistance in real time due to unavailability or the high number of requests and, therefore, it may be necessary to book an appointment in advance.

In light of this, before proceeding with any changes, carefully consult the information on the use of the service valid for your identity provider. However, keep in mind that the impossibility of changing the number independently is a rather rare possibility, generally valid for SPIDs associated with legal entities and with the third level of authentication active.

In any case, always keep the old telephone number at hand, until you are notified in an “official” way: if something goes wrong, you could be “locked out” of your SPID!

How to change phone number on SPID

Having clarified the preliminary aspects of the matter, the time has come to show you, in practice, how to change the phone number on SPID. In principle, you can complete the entire procedure – provided that the certifying body associated with your identity allows you to make changes independently – using any browser for computer, smartphone or tablet and following the steps indicated below.

First, visit the home page of the identity provider with which you obtained the SPID credentials, press the button to access the SPID profile and, when prompted, enter the email and password associated with your digital identity, in the appropriate fields. If necessary, pass the second level of authentication, using the dedicated app or by entering the OTP code received via SMS.

Then reach the ProfileUserPersonal Data or similar section, generally located at the top or to the side, to access the summary page containing the information related to your person.

Therefore, press the button to change personal data, locate the box dedicated to the telephone number and specify the new address to use, making sure to enter it correctly. If you have not been asked to pass the second authentication factor at login, you will need to do so at this stage.

Now press the button to confirm the change and wait for the OTP control code to be received on the new number specified: it should be delivered to you via SMS. When this happens, enter the disposable code in the verification field and press the button to continue, in order to complete the operation.

As you can easily imagine, each certifying body has a characteristic data modification system, therefore I cannot indicate the exact sequence to follow in your case. However, as a concrete example, let me explain how to change the phone number on the SPID identity of some of the most popular identity providers.

The modification of the data (and of the telephone number) for the PosteID identity of Poste Italiane can be completed independently, simply by using a PC, smartphone or tablet connected to the Internet.

If you do not have the device associated with PosteID with you or, for some reason, you cannot use the app, after logging in to SPID with username and password, choose to Access via SMS code by clicking on the appropriate link, press the Continue with SMS button and enter the code that should have been sent to you via a message on the telephone number associated with SPID, in the appropriate field. To finish, click on the Continue button and wait for the login to complete.

If you have problems completing the procedure or if, unfortunately, you are no longer able to access your SPID identity due to a change that is not fully completed, I recommend that you get in touch with Poste Italiane, by calling the dedicated call center on the number. 800.007.777 (the call is free and the service is available from Monday to Saturday, from 08:00 to 20:00), using one of the other contact channels available or by reaching the nearest post office in person.
