Locating the serial number depends on the form factor of the device. On Lexar SD and microSD cards, the number is typically etched in very small, faint gray text on the back of the card, often near the gold contact pins. For USB flash drives, the serial number is usually engraved on the metal connector that plugs into the computer port. On larger devices like Internal or External SSDs, the number is printed on a white sticker label located on the casing, clearly labeled as SN or S/N followed by a string of alphanumeric characters. | | Print Quality | Laser-etched or micro-printing
This is the most common reason users search for this information. Lexar offers impressive warranties—often ranging from 5 years to a limited lifetime warranty depending on the product.
