General Information
As part of the M365 service from Dell you will receive a service tag associated to your license. This service tag is being provided to help expedite your interactions with our service team.
The Dell Service Tag is a 7 alphanumeric character code, and the associated Express Service Code is a 10 to 11-digit code that is a numeric version of the Service Tag. Dell uses these identifiers to access information about customers products, specific tech specs and warranty so that we can provide personalized support options.
IMPORTANT Note: Please keep a note of the service tag and Express Service Code. If requested, please provide it to the service agents or prompted requests.
For software purchases, service tags are distributed by email. If you do not have your service tag and you require support, you can still contact our service team and the agent will still be able to provide you service using other options.
