Number porting

Move your existing number to SureVoIP

SureVoIP can "port", i.e. move your existing number or numbers to us (a communications service provider). This enables you to change a single line number into a multi line number. For example, a single number on a single line can support one call, but once you've moved that number to VoIP, you can have many calls at the same time (as much as your internet connection can handle). If you move office you can still keep your numbers. Many customers do this if they move office so they don't lose their advertised numbers. 

Please note:  when you port a number away from your provider, they will cease that line and all its associated services, such as broadband. If your number has associated services, you will need to transfer these services to the new number before attempting to port to SureVoIP.

  • You can choose nice and easy to remember numbers (one-off fee)


Porting Timescales

The process of porting a geographic number takes up to two weeks (usually 10 days for a single number), the detailed time scales being:

  • 1 single line request = 10 working days
  • Up to 10 single lines = 20 working days
  • PBX 10 lines or less = 14 working days
  • PBX 11 or more (or a centrex site) = 22 working days
  • Simple DDI = 22 working days
  • Complex DDI = 27 working days
  • ISDN 10 lines or less = 14 working days
  • ISDN 11 lines or more = 27 working days


Porting Costs

  • 1 single line - £20.00
  • Up to 10 single lines - £100
  • 10 PBX lines or less - £100
  • 11 or more PBX lines (or a centrex site) - £200
  • Simple DDI block of 10 - £100
  • Complex DDI block of 11+ - £200
  • Up to 10 ISDN lines - £100
  • Over 11 ISDN lines - £200

(All prices are excluding VAT)

Please note: that any re-submissions/changes are charged at £20 + VAT. You will also be charged this amount for any numbers you port, but then do not use or cease. It may therefore be beneficial to cease the numbers with the current providers before putting through the port request to minimise cost.

Geographic numbers are telephone numbers that begin with 01 and 02. For numbers beginning with 03 and 08, please see non-geographic information below.

Non-geographic Number Porting

Non-geographic numbers are numbers that begin with 03 or 08.

Porting non-geographic numbers can take typically 20 working days, but this can vary depending on the amount of resellers involved in the supply chain.

Porting non-geographic numbers to SureVoIP cost:


  • Single non-geographic number = £65
  • Up to 10 contiguous non-geographic numbers = £100
  • Up to 100 contiguous non-geographic numbers = £250


Porting non-geographic numbers away from SureVoIP cost half of the porting in cost.

Non-geographic Number Porting Procedure

Non-geographic porting follows a different procedure than geographic numbers (above). Please contact us for the required porting documentation to port your non-geographic number to SureVoIP.
