Which kinds of numbers make nuisance calls?
How often each kind was marked spam
| Number starts with | Reports | Marked spam |
|---|---|---|
| 03 (UK-wide numbers) | 48 | 69% |
| 01 (landlines outside London) | 182 | 66% |
| 02 (London and other cities) | 93 | 52% |
| 07 (mobiles) | 656 | 46% |
Caller ID can be faked, so the number shown is not always the number that really called.
Most reported area codes
Landline area codes with the most reports. A local-looking code does not mean the caller is local: call centres rent numbers in many areas.
Range holders with the most reported numbers
The phone company that Ofcom gave the number range to. This is not the caller: range holders pass numbers on to businesses and other providers, and mobile numbers can move network.
| Range holder | Reports | Numbers | Spam |
|---|---|---|---|
| Telefonica UK Limited | 164 | 160 | 47% |
| Hutchison 3G UK Ltd | 163 | 149 | 48% |
| Vodafone Limited | 125 | 116 | 39% |
| EE Limited (former T-Mobile ranges) | 118 | 114 | 44% |
| BT | 69 | 56 | 52% |
| Voxbone SA | 50 | 41 | 56% |
| Gamma Telecom Holdings Limited | 39 | 30 | 59% |
| EE Limited (former Orange ranges) | 32 | 28 | 59% |
| TAP GATEWAY LTD | 22 | 6 | 82% |
| Sky UK Limited | 20 | 20 | 55% |

Reports per week

70 numbers (8% of all reported numbers) were reported by two or more people, and the most reported single number has 11 reports. A number reported again and again is usually a call centre or an automated dialler working through a list.
How we count
- Every figure comes from reports that visitors sent on Who Calls You about a call or text they received, after moderation (rejected reports are left out).
- The figures cover every approved report from 26 October 2026, when the first report arrived, to the end of the day before the last update. They are worked out again every Monday morning.
- Times are UK time and show when the report was sent, which is usually soon after the call.
- Network and area facts come from Ofcom's numbering allocations and Google's libphonenumber data, not from the reports.
- People report the calls that bother them, so the figures lean towards unwanted calls. They describe what our visitors experienced, not every call made in the UK.
