Check Computer Age by "Property of Mercer" Sticker

Every Mercer-supported computer has a "Property of Mercer" sticker containing an identification number beginning with "RT". In 2010, this number began including the year and the month the machine was deployed. The sticker is usually placed in the following locations:

  • Dell Desktops:  On top of the computer, near the front.
  • Dell Laptops:  On the back of the display.
  • Apple Desktops:  On the back of the computer.
  • Apple Laptops:  On the bottom of the laptop.
  • MS Surface Tablets:  Under the kick-stand.

If the RT number is 7 digits long, the first 2 numbers represent the year the device was deployed, and the next 2 numbers represent the month.

For example, if a computer has a sticker with RT1201326, it was deployed in January 2012.

If the RT number is not 7 digits long, the computer's age must be verified by the serial number or service tag. See below for instructions.
