Code of Practice for numbers in 'closed' ranges

01 December 2001

The Code of Practice (CoP) governs the provision of service on number ranges in use but not open for new business, eg 0500 and 0800 6-digit numbers. It also covers numbers in migration ranges that are closed to new business, eg parts of the 0845 and 0870 number ranges. The CoP is to be observed by operators with allocations of numbers in closed/migration ranges and by operators in receipt of numbers ported from such ranges.

The CoP comes into force on 1 December 2001.
