What is an AP number and where can I find it?

Each year that you take AP Exams, you get a unique eight-digit AP number that serves as your official identifier for the exam administration. We use the AP number to associate you with your scores. 

Your AP number appears on the bar-coded number labels in your AP Student Pack that you affix to your exam materials. You may have placed a label on your AP number card from your student pack and saved it in a safe place. 

If you’re asked to verify your AP profile when you sign in to your online account, you’ll have to enter your AP number and the year that you tested with that number (remember that your AP number is different each year).
