How Do I Find My Model Number or Product Number?

  • PrintPrint
HP provides a model name on the front of the desktop computer, but this name or number may not be sufficient to get proper support for your computer. These names or numbers often represent a series of many desktop computers that look similar, but have different options and parts. For example, HP has produced over a hundred types of HP Pavilion 700 Desktop models in different configurations, such as the HP Pavilion 725n-us Desktop PC and the HP Pavilion 763k-ap Desktop models.
This document describes how to find the model number (also called the product name) for your HP Desktop PC. You can use the model number or the product number to download drivers, find helpful documents, or get on-line support.
NOTE:If needed, you may also use this document to find the serial number which is always listed near the product number.

NOTE:Some desktop computers are sold in a bundle with a monitor, scanner, and/or printer. The bundle of products is identified by a "-b " after the model name. To find information for the desktop computer inside the bundle, search for the model name without the “-b ”. For example, to find information on the 533w-b , search HP's Web site for 533w . To find information about another product in the bundle, such as a printer, look for its model name on a label adhered to the body of the product.
