In case you have updated your Aadhaar card recently or if you had to change your address and you came across the word SRN which means Service Request Number. UIDAI generates a unique number when you ask for an update - handy for monitoring your demand's progress. Let's explain it in a very simple way.
What Does SRN Mean?
SRN means Service Request Number. It is an exclusive identifier code which appears in your local updation contact or online when you perform an operation on your Aadhaar; an example will be the change of the address, correction of details or re-print of your Aadhaar ordering.
When Is SRN Generated?
You can get an SRN if you are in the following situation:
In case of submitting an offline or online Aadhaar update, by asking for a PVC Aadhaar card or a reprint.
Correction in demographic and biometric data raise.
The moment your request is delivered and acknowledged, the SRN is created by the UIDAI local server.
What Does the SRN Look Like?
The representation of the number might be different:
The majority of the sources claims that it is a 14-digit number.
It is a 28-digit number in case one applies for an update online.
The bottom line is: the SRN/URN will be there on your printed acknowledgment slip or onscreen once you submit a request.
Where to Find Your SRN?
There are a few options where you can locate your SRN:
An acknowledgment slip that is given to you or printed out after you finish your update request by SMS or email (only if you have registered your contact details).
If it’s not with you, you can still find out the status of your update via the UIDAI website using your Aadhaar number.
How to Use the SRN?
With the SRN in your handy, follows these steps -
Come to the “Check Aadhaar Update Status” page on the UIDAI website
Put down your Aadhaar number + SRN (or URN) + captcha
Click the Submit button, and then it will show you the status of your request (Processing, Approved, Rejected)
Conclusion
We may think of SRN as nothing but a string of characters, but it is, in fact, the main key for tracking your Aadhaar requests. Holding your SRN after you update your details is as important as the update itself. Should you need to know the progress of your request or ask UIDAI about it, you will require it. It's the 'update process' rescue.
