Virgin Media O2 (Telefonica UK, Virgin Media) phone number blocks in the UK
Virgin Media O2 holds 184.3 million phone numbers in the United Kingdom, 16.0% of the numbers Ofcom’s table of 2026-09-27 lists as allocated there, under 3 holder names; the largest, Telefonica UK Limited, holds 161.3 million. The carrier a phone lookup names for a number is the holder of the block the number sits in, as the regulator lists it: the original allocation, not the caller, the app or the network that serves a ported number today.

The legal entities Ofcom lists
Every holder in Ofcom’s table that the brand map groups under Virgin Media O2, by the numbers allocated to it. Names are printed as the regulator writes them. Holdings are counted in numbers, not table rows, because rows differ in size: a block covers every ten-digit number its digits start, 10,000 for a six-digit block and 1,000 for a seven-digit one.
| holder | blocks | numbers |
|---|---|---|
| Telefonica UK Limited | 1,627 | 161,341,000 |
| Virgin Media Limited | 3,220 | 19,905,100 |
| Virgin Mobile Telecoms Limited | 31 | 3,100,000 |
How a lookup reads these numbers
The numbering plan types these ranges itself, so a number’s line type comes from the range, not from the holder. Virgin Media O2’s numbers by the plan’s type:

|---|---|---|
| geographic (fixed line) | 14,443,100 | 7.8% |
| pagers | 3,800,000 | 2.1% |
| premium rate | 2,170,000 | 1.2% |
| shared cost | 1,624,000 | 0.9% |
| non-geographic (UAN) | 1,601,000 | 0.9% |
| personal numbers | 1,000,000 | 0.5% |
| freephone | 198,000 | 0.1% |
| not typed by the plan | 10,000 | 0.0% |

What this page cannot say
- A regulator’s table records the original allocation of each block, never who serves a number today: a number ported away from Virgin Media O2 keeps its block, and a lookup still names the block’s holder for it.
- The carrier a lookup names is not the caller, the app or the subscriber. Caller ID can be spoofed, so the holder of a calling number’s block may not have carried the call at all.
- Spaw does no reverse lookup and names no subscriber: nothing here says who owns or uses any number.
- Shares are shares of the regulator’s own table, not of subscribers, lines in service or traffic.
- The grouping under Virgin Media O2 is Spaw’s carrier brand map of 2026-09-24: legal entities, subsidiaries and former names under the brand the network trades as today. Networks change hands, and the map is reviewed at least yearly.
Virgin Media O2 and the other brand names on this page are trademarks of their owners, used only to name the networks the regulators’ tables list. Spaw is not affiliated with any of them.
