a white label on the assembly that contains alpha characters XX-0XXXXX where the X's
could be any characters. The actual part number is shown as the second set of X's starting
with the 0. So with the characters CN-0MD666, the Dell

particular item following the letters P/N.
What is the Service Tag or Express Service Code?
The Service Tag is an alphanumeric (contains both numbers and letters) code that acts like a
serial number for the product to which it is attached. It can be found attached as apermanent
label on every Dell computer and many other standalone Dell products. Service tags contain
everything Dell needs to identify a system and its components as well as that product's warranty
information. This allows for more effective troubleshooting and warranty support of Dell products.
The Express Service Code is a numeric (number only) version of the Service Tag provided to
customers for quick access into Dell's phone support system. When calling Dell, using the
Express Service Code allows customers to connect directly to the operator or technician queue
for their product and shortens wait time.
