How to Find the Serial Number (S/N) on Your TP-Link Device

Your TP-Link serial number (S/N) is a unique identifier printed on every TP-Link device. You may need it for product registration, warranty claims, or RMA requests. Knowing how to do a TP-Link SN check is handy. TP-Link serial numbers are 11, 12, or 13 hexadecimal digits. There are two places to find and check your serial number: on the product box or on the label attached to the device itself.
