Contacting Dell
NOTE: If you do not have an active Internet connection, you can find contact information on your 
purchase invoice, packing slip, bill, or Dell product catalog.
Dell provides several online and telephone-based support and service options. Availability varies by 
country and product, and some services may not be available in your area. To contact Dell for sales, 
technical support, or customer service issues:
1.
Visit dell.com/support
2. Select your support category.
3. Verify your country or region in the Choose a Country/Region drop-down menu at the top of page.
4. Select the appropriate service or support link based on your need.
Locating Your System Service Tag
Your system is identified by a unique Express Service Code and Service Tag number. The Express Service 
Code and Service Tag are found on the front of the system by pulling out the information tag. 
Alternatively, the information may be on a sticker on the chassis of the system. This information is used 
by Dell to route support calls to the appropriate personnel.
