Business phone systems for the CB postcode area
CB covers Cambridge and the surrounding parts of Cambridgeshire, on the 01223 and 01353 dialling codes. We set up cloud phone systems and local numbers for businesses right across the area, from £19 per user a month.
Where the CB postcode area covers
The CB postcode area is named after Cambridge and stretches across Cambridgeshire. Towns inside it include:
- Cambridge
- Ely
- Newmarket
- Saffron Walden
Phone numbers here normally start 01223 and 01353. Because our lines are cloud based, the postcode of your premises doesn't limit which number you can use — you can keep a 01223 number if you move office within Cambridgeshire, or add a second number for another town entirely.
Postcode boundaries and dialling code boundaries don't line up exactly, so a few addresses at the edge of CB sit on a neighbouring code. If you're not sure which applies to you, tell us your address and we'll check before you order.

Switching
Moving a Cambridge business off old lines
Most businesses in CB are still on copper PSTN lines or an ISDN system that has to be replaced before the network is retired. Swapping to a cloud system removes line rental, keeps your existing number and gives you call routing, voicemail-to-email and a mobile app on the same plan.
Porting your number takes around 5 to 10 working days. Your old line keeps running until the port completes; on cutover day there is a short window where calls may not connect, so we agree a time with you and recommend pointing a mobile at the business in the meantime.
