Updating details like your name, gender, or address at a center costs ₹75. The same goes for submitting ID or address proof.
But here's a tip: if you upload documents online through UIDAI's portal (and do it on time), there's no charge.

UIDAI suggests double-checking official fees before heading to a center so you don't get overcharged.
All listed fees already include taxes, so no surprises!
