Equipment MAC Address or MAC ID (Serial Number)
A Media Access Control (MAC) address or MAC ID is a unique identifier assigned to Spectrum equipment for communications on our network. A MAC address/ID (serial number) is displayed in a group of 12 characters, including numbers and letters, and is generally found on a sticker located on the bottom or rear of your Spectrum device.

When entering the last four digits of the MAC address (serial number) to reset your password or retrieve your username, don't use EMAC or CN, and be sure to include numbers and letters only. If you're activating your modem online, don't use CMAC.
