Online Gazette Application Form
A parent finds out the Aadhaar of their child is Rahul but school records show that the child is Rahul Kumar. The Transfer Certificate (TC) names must be similar to the school records. The Aadhaar Seva Kendra desires the Birth Certificate. The Birth Certificate indicates a slight difference between the two. At this point, no one knows exactly which document to amend first.
This is what is often misunderstood about minor Aadhaar card name changes in Karnataka—it is seldom just one piece of paper. It's a chain. If you pull the wrong link, you are essentially restarting the entire process. This guide explains how the chain works, which document forms the basis of the update, and how the procedure varies with the child's age.
Why the Child's Age Changes Everything
UIDAI does not treat a 3-year-old and a 13-year-old the same way. Whether you need biometrics depends on the age group your child belongs to, and this dictates the entire procedure.
- Kids under 5 years - Blue Aadhaar (Baal Aadhaar): Children below 5 are issued blue Aadhaar cards. There are no biometrics at this stage. The card is demographic only (name, DOB, address) and linked to a parent's Aadhaar. Correcting names here is relatively simple with minimal documentation.
- Children 5 to 15 years: Biometrics enter the scene once a child passes 5. A Mandatory Biometric Update (MBU) is required (fingerprints and iris scan). If your child is in this range, the biometric update happens at the same time as the name correction.
- Children above 15 years: Another biometric update is required at 15 to finalize the record. This usually coincides with any other updates you are carrying out.
The One Document That Anchors Everything: Birth Certificate
The Birth Certificate is the non-negotiable starting point for child updates in Karnataka. Not the school ID, not a parent's Aadhaar, and not a letter from a teacher.
In Bengaluru, this must be issued by the BBMP (Bruhat Bengaluru Mahanagara Palike) or the appropriate municipal authority. A certificate from a private hospital that is not municipal-registered has no legal weight for Aadhaar updates. Ensure yours is stamped by the registrar and has a valid certificate number.
- Fix the Birth Certificate at the municipal office first (requires an affidavit and a few weeks).
- Provide a certificate from a school principal as a supporting Proof of Identity (POI).
Documents Required for Child Aadhaar Name Change Karnataka
1. Proof of Identity (POI) - Select one:
- Birth Certificate: Issued by BBMP or Karnataka municipal body (The best document).
- Passport of the Child: Only valid if the correct name is already updated in the passport.
- School Headmaster Certificate: From a Government or recognized school, on official letterhead, with the child's name, DOB, and photograph.
2. Proof of Relationship (POR):
- Aadhaar Card of Parents: At least one parent must be present to authenticate the update using their own biometrics.
How to Change Child's Surname in Aadhaar Card Karnataka
Surname changes often arise from remarriage, adoption, or fixing a maiden/married name mismatch. There are two paths:
- When the Birth Certificate is enough: If the Birth Certificate already shows the correct surname (because the municipal record was corrected), simply take it to the Seva Kendra.
- When a Karnataka Gazette Notification is needed: If the Birth Certificate has the old surname and you want a new one on Aadhaar, an affidavit is not enough. You will need a Karnataka Gazette Notification (published by the DPSP Mysore Road office or e-Rajyapatra portal).
- Post-Adoption: You will need the legal Adoption Deed and a revised Birth Certificate or a Gazette notification with the new surname.
Step-by-Step: The Update Process (2026)
Step 1: Finalize School Records
Ensure the desired name is already in the school records before visiting the ASK. This prevents future mismatches between Aadhaar and School TCs.
Step 2: Correct the Birth Certificate
Ensure the spelling and name parts match exactly what you want on the Aadhaar. If not, rectify it at the BBMP/Municipal office first.
Step 3: Book an Appointment
Book a slot on the UIDAI portal. In Bengaluru, BangaloreOne and KarnatakaOne centers often have shorter wait times than dedicated ASK centers.
Step 4: Physical Presence
Both the child and the parent must be present. The parent (guardian) will authenticate the request via their fingerprint.
Step 5: Fill the Update Form
Write the full name in CAPITAL LETTERS exactly as it should appear. Double-check every character.
Step 6: Document & Biometric Scan
The operator will scan the documents. For children 5+, fingerprints, iris scans, and photographs are captured.
Step 7: Acknowledgment & Fee
Pay the ₹50 fee for name correction. Mandatory Biometric Updates at 5 and 15 are typically free. Save the URN to track status.
Frequently Asked Questions (FAQs)
What are the primary Aadhaar card name correction documents for child updates?
The principal document is the Birth Certificate issued by BBMP (Bengaluru) or the municipal registrar. If the Birth Certificate lacks a full name, a School Principal's certificate (from a recognized school) or a Passport is also accepted as POI.
Is the parent's presence required for a minor Aadhaar name change in Karnataka?
Yes. At least one parent must accompany the child. Their Aadhaar must be linked to the child's profile, and they must authenticate the update using their biometrics.
Can I do a Birth Certificate to Aadhaar name change Karnataka online?
No. Minor updates require physical biometric verification and parent authentication. The online portal does not support name updates for minors; you must visit a center in person.
How to change a child's surname in Aadhaar after adoption?
You need the legal Adoption Deed (court decree). Along with it, you must provide either a revised Birth Certificate or a Karnataka Gazette Notification reflecting the new name.
My child is 6 years old. Do I need biometrics for a name change?
Yes. Since the child has passed age 5, a Mandatory Biometric Update (MBU) is required. Fingerprints and photographs will be captured during the name correction visit.
Can a school ID card be used as a name correction document for a child?
Only if the school is Government-run or Government-recognized. The ID must have the child's name, photo, and DOB. However, a Headmaster's Certificate on official letterhead is more reliably accepted.
What is the fee for minor Aadhaar name change in Karnataka?
The name correction fee is ₹50. If it's done alongside a Mandatory Biometric Update (at ages 5 or 15), the biometric part is free, and the total fee remains ₹50.
Does the Birth Certificate need to be in English or Kannada?
Either works. Aadhaar handles both languages via transliteration. If the Kannada version is incorrect after the update, you can request a transliteration correction in a subsequent visit.
How long does it take for the update to reflect?
Most updates take 10 to 20 days. You can track the status using the URN and download the e-Aadhaar once approved.
Can I use a Tehsildar's certificate for my child's Aadhaar name fix?
Yes. A certificate on official letterhead signed by a Group A Gazetted Officer or Tehsildar is an accepted POI for minor updates, especially if the Birth Certificate has errors that take time to fix.
