MAC number

Our MAC number arrived by email on Wednesday morning and we've started the switch process. We should be on our new ISP by 14th February.
fingers crossed.

What is a MAC code?

I thought I'd look up what a MAC code was and how long it took to get.

I've read some ISPs give it within 15 minutes by email. That's pretty fast!

A MAC is a unique code, identifying a particular line. It comes in two formats. You do not need to worry about which format is used:

• a code consisting of four letters that identify the underlying service (BBIP, FTIP or BBDS) followed by between seven and nine numbers, a slash, and five alphanumeric characters (e.g. BBIP1234567/1F6HT); and
• a code consisting of four letters (LLUS), followed by six digits followed by four further digits showing the expiry date (i.e. LLUS123456ddmm).

A MAC code is only valid for 30 days.
