The 60-second version
Aadhaar mobile mismatch blocks e-KYC, UPI, and IT portal OTP. I update at Seva Kendra with OCI/passport address proof, then re-verify bank, demat, and GST within 90 days.
Without old-phone OTP, Seva Kendra biometric is the only lane
Returning NRIs often have Aadhaar linked to a foreign or dormant Indian number — bank e-KYC fails until UIDAI database matches active SIM.
Book Aadhaar Seva Kendra appointment with passport, OCI booklet, and Indian address proof; biometric update takes 72 hours to propagate.
After update, re-run bank KYC, mutual fund OTP, and income-tax portal Aadhaar authentication.

OCI without Aadhaar?
Eligible with 182+ days address proof — enrol then update mobile.
Two mobiles on Aadhaar?
Only one — new replaces old.
NRIs abroad updating?
Seva Kendra India only for no-OTP path — plan visit on landing.
Bank still fails?
Wait 72h; if persists, bank manual NPCI refresh ticket.
Charge for update?
₹50 standard at ASK — verify board at appointment.
Child Aadhaar?
Parent biometric for minor — same Seva Kendra process.
The plan is only as good as the sequence.
Tax, banking, schools, shipping — they all have dependencies. A wrong order costs months and lakhs. Get it right.
