How close to my GMAT exam date can I still change personal details like my date of birth?

Quick Answer verified

You can update personal details such as your date of birth up to 72 hours before your scheduled GMAT exam. Once you are within 24 hours of the test, GMAC locks the appointment completely, so no changes to your centre, date, or personal information are possible at that point.

You can change personal details on your GMAT registration, including your date of birth, only up to 72 hours before your scheduled exam. Once you cross that mark, GMAC treats the booking as locked. Missing this window means you will have to live with whatever details are already on file for test day.

Why This Matters for Your Admit Card

Your GMAT admit card must match your passport exactly, so an error in your date of birth or name can turn into a bigger problem once the 72 hour window closes. If you spot a mistake early, correcting it is straightforward, but leaving it for the final day puts you at risk of being turned away at the centre.

My Advice

Review your registration details the moment you book your GMAT slot, not the week before, so you have plenty of room inside that 72 hour cutoff to fix any typo in your name or date of birth.
