I need to know my Repair ID

Hi adrianedp1983,

To find your Case or Repair ID for support, service, or repairs, sign into My Support [ https://mysupport.apple.com/ ] with the same Apple ID that you used to start your support, service, or repair, then look under the Recent Activity section.

For service and repair, you can also find your Repair ID in the confirmation email that you receive from Apple.
