Serial numbers and lot codes contain information about the product that Corsair can use to provide support. They are often preceded by “S/N:” or sometimes “Lot Number” and frequently appear next to a bar code. They are usually the longest sequence of numbers you’ll see on the label.

Corsair packaging typically has the serial number on it. If the packaging is unavailable or does not include the number, many Corsair products have the number printed on stickers in the following places:

• Corsair system: On the bottom; the part number should begin with CS
• Headsets: Inner side of headband, near left earcup; requires extension of headband
• Cases: Rear panel, often near PSU slot
• Cooling: Side of radiator
• Fans: Top edge
• Solid state drives: Drive face
• Mice: Label taped around the cable or, for wireless, on underside of mouse and on USB dongle
• Keyboard: Underside of keyboard, near cable attach point
• Memory module: Side of module
• PSU: Side or top of unit
• Speakers: Back of subwoofer
