UK phone number datasets
Everything on this site is built from documented, reproducible datasets — primarily Ofcom’s weekly UK Numbering Data publication, re-processed into the tables below (last refreshed 10 July 2026). Each dataset has a browsable HTML surface and, where practical, a flat CSV download. Reuse is welcome under the Open Government Licence v3.0 with attribution — see methodology for the pipeline and sources for upstream credits.
