Every HP product has a product number and unique serial number. Reference these numbers when working with customer support agents, finding drivers and support documents, servicing the product, or determining warranty status.
The name and number on the front of the product might not be sufficient to get proper support. These names and numbers often represent a series of many product models that look similar, but have different options and parts.
In addition, the name and number on the front of the product might vary by country/region. The best way to find HP product information or to confirm your warranty status is to find your product name and model number (or Product NO or P/N on labels) and serial number (or Serial NO, S/N, or SN on labels).
Product name and model number (or Product NO or P/N on labels): Identifies your product in a series (for example, HP Spectre Folio - 13-ak0001na, 6H8W2PA#ACJ). Use this information to download the correct drivers and apps and find support documents.
Serial number (or Serial NO, S/N, or SN on labels): Identifies your specific HP product. Use this number to service your product, find warranty status, or work with HP Customer Support representatives.

To find ink and toner cartridge numbers, go to HP Printer Ink, Toner, & Cartridges.
Most cartridges do not have a serial number.
Product name (or model number): This is the printer brand name typically found on the front or top of the printer. HP Tango and HP DeskJet 2545 are examples of product names.
Extra letters in a product name indicate differences between the same types of printers. For example, the HP LaserJet Pro M125a supports USB connections only. The HP LaserJet Pro M125nw supports wireless and wired network connections.
Series name: A group of similar printers. For example, an OfficeJet Pro 8720 Printer series contains the OfficeJet Pro 8720, 8725, and 8728 printers.
Serial number: A unique number that represents a single printer. Every printer that HP releases has its own unique serial number applied to the surface of the printer.
Product number: A small, one-word name that represents an exact model of printer. K7C85A and M9C7A are examples of printer product numbers.
Find the product name, number, and serial number on the label on the printer. The label might be found inside the printer cartridge access area or on the back of the printer. For some older printers, it might also be found on the bottom of the printer.
