Standard Operating Procedure: Aadhaar Date of Birth (DoB) Update

This Standard Operating Procedure (SOP) outlines the mandatory protocols for updating the Date of Birth (DoB) in an Aadhaar record. As per the Unique Identification Authority of India (UIDAI) guidelines, the DoB can be updated only once in a lifetime, provided the request falls within the permissible variance limits. This document is designed for Enrolment Operators and residents to ensure compliance, data integrity, and error-free processing.

Section 1: Pre-requisites and Documentation

Before initiating the update process, ensure all requirements are met to avoid rejection.

• Original Documents: Only original scanned copies of Proof of Date of Birth (PoDoB) are accepted. Refer to the UIDAI list of valid documents (e.g., Birth Certificate, SSLC/Matriculation Certificate, Passport, PAN Card).
• Mobile Number Linkage: Ensure the registered mobile number is active and accessible to receive the One-Time Password (OTP).
• Biometric Verification: The resident must be physically present at the Aadhaar Enrolment Centre (AEC) for biometric authentication if self-service online modification is not feasible.
• Verification of Limits: Confirm via the Resident Portal or Operator dashboard that the DoB has not been updated previously (the "Once-in-a-Lifetime" rule).

Section 2: Step-by-Step Execution Workflow

Follow these steps strictly to process the modification request.

Step A: Identification and Authentication

• Validate the resident’s Aadhaar number against the existing database.
• Perform biometric authentication (Fingerprint or Iris scan) to authorize the operator and the resident.
• Collect the Request Form (Enrolment/Correction form) duly filled and signed by the resident.

Step B: Data Entry and Document Upload

• Access the Client Application (ECMP) and select the "Update Request" module.
• Input the correct Date of Birth exactly as it appears on the supporting document.
• Scan the original document in color (minimum 200 DPI resolution) and upload it to the system.
• Cross-verify the scanned document with the entry made in the client software for consistency.

Step C: Verification and Finalization

• Display the "Preview" screen to the resident to confirm the accuracy of the new DoB.
• Obtain the resident’s signature on the physical form and digital signature on the tablet.
• Generate the Update Request Number (URN) acknowledgement slip and hand it over to the resident.
• Instruct the resident to track the status via the official UIDAI website using the URN.

Section 3: Pro Tips & Pitfalls

• Pro Tip: Always advise the resident to bring multiple forms of ID if the primary document name/DOB has any discrepancies.
• Pro Tip: Ensure the document being uploaded is clear; blurry or cropped document scans are the primary cause of rejection by the Verifier.
• Pitfall (The "Variance" Rule): If the requested DOB change is greater than 3 years, the request will be marked as an "Exception Case," requiring additional administrative verification.
• Pitfall (Name/Gender mismatch): Ensure the name on the DOB document matches the name on the Aadhaar record. If names differ, a Name Change request must be processed prior to or alongside the DOB change.

Section 4: Frequently Asked Questions (FAQ)

Q1: Can I change my Date of Birth online without visiting an Aadhaar Centre? A: Yes, if your mobile number is linked to Aadhaar, you can initiate a self-service update online via the MyAadhaar portal. However, you must upload a self-attested supporting document.

Q2: How long does it take for the Date of Birth update to reflect in my Aadhaar? A: Generally, updates are processed within 7 to 30 working days. You can track the status using your URN on the UIDAI 'Check Aadhaar Update Status' portal.

Q3: What if I have already updated my Date of Birth once in the past? A: According to UIDAI policy, the Date of Birth can be updated only once in a lifetime. If you have already utilized this opportunity, further changes may require a visit to a Regional UIDAI office with a formal request and evidence of a genuine clerical error.
