It can take up to 72 hours for the updated number to reflect across all Aadhaar-based services.
You’ll receive a URN (Update Request Number) on your acknowledgement slip — use it to check update status on the UIDAI portal.
From authentication to online address updates, your new number will receive all Aadhaar-linked OTPs.
