Business phone systems for the OX postcode area

OX covers Oxford and the surrounding parts of Oxfordshire, on the 01865 and 01295 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 OX postcode area covers

The OX postcode area is named after Oxford and stretches across Oxfordshire. Towns inside it include:

  • Oxford
  • Banbury
  • Bicester
  • Witney

Phone numbers here normally start 01865 and 01295. Because our lines are cloud based, the postcode of your premises doesn't limit which number you can use — you can keep a 01865 number if you move office within Oxfordshire, 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 OX 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 Oxford business off old lines

Most businesses in OX 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.
