Calls from 0909 505 XXXX
Block 0909 505 XXXX is allocated by Ofcom to Dynamic Mobile Billing Limited, on the UK Premium rate exchange (allocated 2001).
0909 505 XXXX is part of the UK premium-rate / service-charge range. Calls to numbers in this range — such as 0909 505 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 — 0909 505 XXXX — was allocated by Ofcom to Dynamic Mobile Billing Limited in 2001. Dynamic Mobile Billing Limited either operates the numbers directly or sub-allocates them to resellers and downstream carriers, which is why a single 0909 505 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.
Insurance and accident-claims cold calls remain a heavy source of unsolicited 0909 505 XXXX-prefix traffic. Since 2019 it has been illegal under UK law to make unsolicited cold calls about pensions, and similar tightening is in force for insurance leads. You can register your number with the TPS for free to block legitimate UK marketing calls.
If a 0909 505 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.
