Your mobile phone number is used for secondary identity verification, and critical security notifications. You can update it from your account security settings.
Users logged in as a RAM user, with a RAM role, or through Enterprise SSO cannot change the account mobile phone number. Ask the account administrator to make this change.
When to change your mobile phone number
Change your mobile phone number promptly in these scenarios:
-
Your original phone number is lost, suspended, or reassigned.
-
Account ownership is being transferred.
-
Your security policy requires periodic phone number rotation.
Prerequisites
Log on to your Alibaba Cloud account. The verification method depends on whether your original phone number is still accessible:
-
Accessible: Enter the SMS code sent to your current number.
-
Not accessible: Complete the verification by receiving a code sent to your logon email address.
Procedure
-
Log on to the Account Center and go to the Security Settings page. In the Basic Settings section, click Modify under Mobile Phone Number.
Alternatively, on the Overview page, in the My Account area, click the
icon next to Mobile Phone Number. -
Verify your identity using your original mobile phone number, logon email, or TOTP.
-
After verification, enter your new phone number, click Get Verification Code, enter the code, and click OK.
Note-
The phone number must match the country or region you selected during registration.
-
If your account has completed enterprise verification, you can bind a phone number from a country or region different from your registration location. This feature is not available for individual-type accounts. For more information about the enterprise verification process, see Account verification overview.
-
A phone number can be bound to up to six Alibaba Cloud accounts. If you reach this limit, use a different number or close unused accounts. Close your Alibaba Cloud account.

FAQ
What should I do if I don't receive the verification code?
-
If your logon email or original mobile phone number is accessible, try resending the code. Troubleshoot missing verification codes during registration or logon.
-
If both your mobile phone number and logon email are unavailable, see What do I do if my logon email address is unavailable? to file an appeal.
Does my logon phone number change when I update my mobile phone number?
Yes. Your mobile phone number is also used for logon and password recovery. After the change, use your new number to log on and receive verification codes.
Does the sponsor contact phone number in the ICP filing system change when I update my mobile phone number?
No. After you change your mobile phone number, the ICP filing information is not automatically updated. The ICP filing sponsor information includes items such as the sponsor name, certificate number, and certificate address, and does not contain a mobile phone number field. To update contact information in your filing (such as the website owner's phone number), log on to the ICP Filing system and modify the filing information separately.
Does changing my mobile phone number affect my account's main region attribute?
No. Binding a Chinese mainland phone number does not affect the main region attribute of your Alibaba Cloud international site account (for example, Hong Kong). This is a standard phone number change operation and does not alter your account attributes.
What should I do if I see "Identity verification is required before this operation" when changing my mobile phone number?
This prompt usually occurs because the session timed out due to a long interval between the identity verification step (for example, email verification) and the phone number change operation. Restart the modification process or try again later to complete the operation normally. No special handling is required.
Can I bind two mobile phone numbers to my account?
An Alibaba Cloud account supports binding only one mobile phone number. This number is used to receive messages and verify your identity (for example, to recover your password or change security settings), and also supports logon by verification code. You cannot bind two mobile phone numbers to the same account at the same time. If you want multiple people to receive notifications, go to Addresses and Contacts and add multiple notification contacts, each configured with its own phone number to receive different types of notifications.
Can I unbind or delete my mobile phone number?
No. Your mobile phone number is the secure phone number bound to your Alibaba Cloud account, and it is a core credential for identity verification and account security. It cannot be unbound or deleted. You can only replace it with a new number by following the procedure in this topic. Your account must always have a valid mobile phone number.
Can the previous holder still receive notifications after I change my mobile phone number?
No. After the change takes effect, the previous mobile phone number no longer receives any notifications for the account, including security notifications and verification messages. Notification privileges are transferred to the holder of the new mobile phone number. If you want the previous holder to keep receiving certain notifications, add that phone number as a notification contact in Addresses and Contacts.
