User:MRSC/National Telephone Numbering Plan

The National Telephone Numbering Plan (NTNP) is a regulatory framework for telephone numbers in the United Kingdom, which is organised and published by Ofcom.

In 2003, Oftel published a draft National Telephone Numbering Plan. Later that year, the data and the responsibility for maintaining it passed to Ofcom.

The National Telephone Numbering Plan is published in two formats. These are the National Telephone Numbering Plan document, which is updated several times a year; and the SABC data files, which are published weekly.
