Can I use a different mobile number to open my account as compared to the number linked to Aadhar?

Yes, you can use a different mobile number, but it’s recommended to use the same number linked to the Aadhaar. In case of a difference in the mobile number/email ID between the EKYC application and Digilocker, your KRA records will be updated with the number and email ID you have used in the EKYC application.
