is extention sticker in the back of driver license......

acceptable as a valid ID. anyone knows or experiences it before? thanks

I would take my passport just in case.

Where I live, a driver’s license is renewed by placing a sticker on the back of the original license to update information such as expiration date and address. Is this acceptable for admittance to the CFA exams? Yes. An original driver’s license (which contains a photo of the driver) with a renewal sticker is acceptable. Your identification must meet all of the following criteria: It must be current and valid, it must contain your photo, it must be issued by a government agency, and it must be a single document. i got it from CFAI FAQ. so yes.

The proctors aren’t always the smartest cookies in the package. The invigilators might be worse. I’d have a passport just in case.
