Hello everyone,
I wanted to share my experience in case it helps others facing the same issue.
I was getting the "identification number not recognized" error on Prometric while trying to schedule my CMA Part 1 exam, even though I had just registered and received my authorization number.
Here's what worked for me:
- My last name contains a non-English character (Ç). When I entered it as "Ç", it didn't work.
- When I used the English version (C), the system accepted it and allowed me to proceed.
- I also noticed that my authorization number was not sent via email. I found it in my invoice/purchase history on the IMA website and used that.
After these steps, I was able to successfully schedule my exam.
Hope this helps anyone experiencing the same issue!
Good luck to everyone.

Hi all,
Update: I registered (paid) for the exam on Saturday, 18/04/2026 at 13:50 and today Tuesday, 21/04/2026 at 02:00 I was able to schedule my exam. From my research and experience, this was a backend issue and you will automatically be able to schedule within 48-72 hours after you receive your authentication email. IMA processes the authentication numbers either immediately or in batches. If it is the latter, it may take upto 72 hours for your authentication number to be active. Don't panic like I did and just continue your preparations for the exam while checking the scheduling site once or twice a day. All the best to all giving the exam!
