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.

Newer products may have a new type of serial number on it that starts with a letter and has a string of letters and numbers. This serial number should be 14 characters long.

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:
