Which companies hold 0344 numbers
Ofcom allocates numbers to phone companies in blocks. These are the operators holding the most 0344 blocks. The company that was issued a number often supplies it onward to a business or reseller, and UK numbers can be ported between networks, so read this as where the number started, and a strong hint rather than proof of who serves it today.

|---|---|---|
| Vodafone Ltd (C&W) | 81 | 20% |
| TalkTalk Communications Limited | 42 | 11% |

What it costs to call 0344
Same price as calling a landline
Ofcom rules say 03 numbers must cost the same as calling an 01 or 02 number, and they must come out of your inclusive minutes if you have them. A company can't make money from you calling its 03 number.
Inclusive minutes: Yes, by regulation. See the full UK call charges guide.
