Update on certain application forms

Numbering Application Forms S8 Section 5 ii) and S9 Section 5 iii) request applicants to select numbers from within a pre-set tariff range. This was because Ofcom historically pre-set tariffs at the 100K (number block) level.

All registered numbering contacts have been advised in a letter from Ofcom that Ofcom no longer sets tariffs at the 100K (number block) level for 09, 0871 or 0844 (excluding 08 Internet only ranges) numbers. Therefore it is no longer a requirement to select from a specific tariff range.

With effect from 30 April 2007, applicants should select a block that is free and Ofcom will set the required tariff to this 10K block. For further information on this change please email: numbering.information@ofcom.org.uk
