To help with a potential issue related to a student's APAAR ID and class change, you should first check the student's details on the APAAR website and verify if there's a mismatch in their demographic information, such as name or date of birth.

If there's a discrepancy, correct the inaccurate data in the student's school records and resubmit the request to generate the APAAR ID.

If you are still having trouble, you can reach out to the school, the APAAR helpline or the toll-free number.

Good luck!!
