Calls from 0844 551 XXXX
Block 0844 551 XXXX is allocated by Ofcom to Citrus Telecommunications Ltd, on the UK Service rate exchange (allocated 2003).
0844 551 XXXX is part of the UK premium-rate / service-charge range. Calls to numbers in this range — such as 0844 551 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 — 0844 551 XXXX — was allocated by Ofcom to Citrus Telecommunications Ltd in 2003. Citrus Telecommunications Ltd either operates the numbers directly or sub-allocates them to resellers and downstream carriers, which is why a single 0844 551 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.
A small share of 0844 551 XXXX traffic is automated — recorded-voice ('robocalls') from political polls, marketing pitches, or scams. Under UK rules, you must have opted in to receive automated marketing calls. If you're getting persistent automated calls from a UK number, report them to the ICO via ico.org.uk.
If a 0844 551 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.
