Calls from 0905 612 XXXX
Block 0905 612 XXXX is allocated by Ofcom to Telecom 10 Ltd, on the UK Premium rate exchange (allocated 2009).
0905 612 XXXX is part of the UK premium-rate / service-charge range. Calls to numbers in this range — such as 0905 612 1234 — incur a service charge in addition to your provider's standard access charge. Ofcom and the regulator PSA cap these charges and require the service charge to be disclosed up-front in any advertising.
This block — 0905 612 XXXX — was allocated by Ofcom to Telecom 10 Ltd in 2009. Telecom 10 Ltd either operates the numbers directly or sub-allocates them to resellers and downstream carriers, which is why a single 0905 612 XXXX prefix can be used by many different organisations. You can verify any allocation against Ofcom's National Telephone Numbering Plan, which is updated weekly.
Calls from 0905 612 XXXX numbers that ask you to 'press 1' or to call back a different number should be treated with caution. This is a classic premium-rate trap — the call-back number is often in the 09xx range and costs several pounds per minute. Never call back an unfamiliar number you've been instructed to dial.
If a 0905 612 XXXX number called you and you're not sure who it was, the safest steps are: don't return the call until you've verified it (search the full number online first), don't share personal or financial details, and register the number with the Telephone Preference Service (TPS) if it's a marketing call. Persistent unwanted calls can be reported to Ofcom and the ICO. To block a specific number on most UK mobiles and landlines, you can also enable network-level call screening through your provider.
