As on every network, some of its numbers are used for nuisance and scam calls, such as one-ring call-back tricks and fake bank, delivery or HMRC calls.

What a Three number can tell you

Every UK mobile number has 11 digits and starts 07. The digits that follow were originally issued in blocks to individual networks, so they hint at where the number started life. But because anyone can keep their number when they switch, a number that began on Three may have moved on, and one from another network may now be with Three.

Many smaller brands also run on a bigger network's masts. Either way, knowing the network tells you nothing about the person calling or whether the call is genuine. That's what the reports are for.

07 number blocks issued to Three

Ofcom has allocated 940 blocks of mobile numbers to Hutchison 3G UK Ltd, starting in 2001. They fall under the prefixes shown below. Each prefix covers a large number of numbers, and because of porting, any of them may now be with a different network.

Questions about Three calls

Can I tell from the digits that a number is on Three?

Only roughly. Every 07 block was first given to a single network, but customers keep their numbers when they switch. A number from a Three block may since have moved away, and numbers from other blocks may have moved to Three.

Who called me from a Three number?

The network won't tell you that, and it says nothing about whether the caller is genuine. Scam and nuisance calls come from every network, and caller ID can be faked. Look the full number up here and read its reports.

How do I report a nuisance call from a Three number?

Forward it free to 7726 so the network can look into it, rate it on its page here so others are warned, and report any fraud to Action Fraud.

Does Three block spam calls?

Most UK networks label or block some suspected spam, but none of them catch it all. Look in Three's app or on its website for the options, and keep checking numbers you don't recognise.
