Monitors without a service tag number purchased from Dell 
When purchased from Dell, you receive a Dell Order and Dell Customer number. This order number automatically "registers" you to the monitor and tells the start and end date of the purchased warranty. You cannot register a monitor via the online tools without a service tag number. The order number also tells us what warranty period you purchased. If you ever need it exchanged while under warranty, you must contact Technical Support for your country (1-866-618-2044 USA) by phone and provide to them the following information -
