Hello,

Your passport number and some of its information are the only documents required for IELTS registration. When you take the IELTS, you're indicating that you want to study abroad or immigrate. For these purposes, you will require a passport. You will require a passport in original form and one coloured photocopy during IELTS registration and on exam day.

For the IELTS exam, a passport is necessary for registration.

It is the only form of identification that is accepted, not a driver's licence or a student ID card. It should be mentioned that the test taker must have their passport with them on the day of the test, and that the passport must be valid and not expired.

Hope it helped
