It seems 2talk have been forced to add an extra digit to their 028 89x xxxnumbers.

The additional digit is added after the 028 89 so existing numbers become 028 899 xxxx

I recieved the following email from 2talk tonight:

Dear Adam,

As of the 1 September 2009 your 2talk 02889 number will be updated to
include an extra digit. This is a regulatory requirement imposed by
the NZ number administration body. You will need to use this digit
when dialing your 02889 number from outside the 2talk network. However,
you do not need to change any of the settings on your phone or device
you use to access 2talk and can continue to use your existing 02889
number and password to access 2talk live.

For reference, the following changes will be made to your numbers:

  Number 028 89 34xx will change to 028 89 9 34xx

Please ensure you advise friends, family and colleagues of this change
so that they can continue to successfully call your 2talk 02889 number.
Until 1st September they should continue to use your existing number.

This change does not affect our 028 25 range of numbers or other 2talk
regional numbers. If you have any questions regarding this change
please contact 2talk support at support@2talk.co.nz

regards
the team @ 2talk
