…and 35 more providers hold smaller allocations in this range.

Ofcom’s data shows the provider each number range was originally allocated to — not who holds an individual number today. Numbers are frequently moved (ported) between providers, and no public database reveals the person or business behind a specific number, so treat any service that claims to with suspicion.

Checks per week (weeks ending on the dates shown). Our own lookup data, counted once per person per number per day, with Ofcom’s drama/example ranges excluded and refreshed weekly. It measures how many people were curious enough to check a number in this range — it is not a count of scam calls, and it says nothing about any individual number. The quarterly nuisance-call prefixes report puts every range side by side.

Scam & cost warnings

0344 numbers are low-risk for callers because Ofcom caps their cost at the 01/02 rate — but scammers still use and spoof them precisely because they look official. An 0344 caller ID is not proof you’re talking to a government body or bank.
