Get the mismatch fixed before document verification — DV officers can reject inconsistent documents.
For a spelling error, update your name on Aadhaar at a UIDAI centre with supporting documents.
If the name genuinely changed, prepare a notarised affidavit for the name change.
Keep the same name format across Aadhaar, certificates and the application form.
Start the correction early — updates and affidavits take time.
Carry the correction proof to document verification along with the originals.
