Ofcom numbering snapshot published 14 Oct 2026
Rangecheck data: CSV files from Ofcom’s numbering register
Rangecheck publishes 7 CSV sets built from Ofcom’s numbering snapshot published 14 Oct 2026. The three full tables are complete: all 745 area codes, all 404 range holders with allocated blocks and all 12 number families. Per-page files exist for the pages on the current layout. Every row carries its release and Ofcom attribution; rows that repeat a figure shown on a page carry that figure’s claim identifier, and every row of the three full tables has its own.
Which CSV files can I download?
| Set | File | Size |

| Number-family pages | /data/number-types/{family}.csv | 6 files |

| Number families | /data/hubs/number-types.csv | 12 rows |
Each file also exists with the release in its name (for example area-codes-fc227d9e.csv); that copy never changes. The file without the release always holds the latest snapshot.
