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 will see on the label.

• Corsair system: On the bottom; the part number should begin with CS
• Headsets: Inner side of headband, near left earcup; requires extension of headband
