candidate id has change

I understand you're experiencing an issue with your candidate ID changing in your AWS certification account, which is preventing you from accessing your exam schedule for the CLF-C02 (AWS Certified Cloud Practitioner) exam.

Unfortunately, AWS re:Post community forums cannot directly resolve account-related issues like candidate ID changes or exam scheduling problems. This type of issue requires direct assistance from AWS Training and Certification customer support.

I recommend you contact AWS Training and Certification support directly. When contacting them, be sure to provide:

• Your previous candidate ID
• Your current candidate ID
• Details about your CLF-C02 exam payment
• Any confirmation numbers or transaction IDs you received

They are the appropriate team to help restore access to your exam scheduling information and resolve the candidate ID discrepancy. Be prepared to verify your identity when contacting them to ensure they can properly assist with your account.
