The MAC ID (or address) is a unique alphanumeric identifier assigned to each device in your network. It is usually printed on a label on the rear or underside of the device, and is used for associating it with certain services both on your network and within the 8x8 system. So it is important that it is recorded accurately.

When discussing MAC IDs over the phone or reading them from handwriting, here are some helpful tips to keep in mind.

  • MAC addresses MUST BE 12 characters.
  • The ONLY valid characters that can be used are numbers 0 - 9 and letters A - F. Therefore, the only valid characters for hex MAC IDs are 1 2 3 4 5 6 7 8 9 0 A B C D E F.
  • The letter O is not a valid character and should immediately be called into question when read out loud as “O.” Whenever you hear “O,” confirm it means 0 (zero).
  • Also watch for G's that look like 6's; B's that look like 8's; D's that resemble 0's; and vice versa.
  • When working with a technical support representative who needs your device's MAC ID, always read back and confirm the 12-character MAC ID.
