Who called me from a KCOM number?
KCOM is a UK fixed-line network operator. Look up any of its 427 Ofcom-allocated number blocks below.
KCOM is a UK fixed-line network operator. That means Ofcom has allocated KCOM one or more blocks of UK telephone numbers under the National Telephone Numbering Plan, which KCOM can either use for its own customers or sub-allocate to resellers and downstream providers. In total, KCOM currently holds 427 allocated number blocks in our copy of the Ofcom plan.
KCOM's number ranges are concentrated in 01482 (Hull), 01405 (Goole), 01539 (Kendal), 01768 (Penrith). Across all of its allocations the split is roughly 423 geographic landline, 2 03 non-geographic, 1 freephone, 1 premium-rate blocks. You can use the tables below to jump straight to a specific KCOM area code or number block and see the common call patterns reported for it.
The oldest KCOM number block in the Ofcom data was allocated in 1994, and the most recent in 2024. Allocation dates matter because a number that has been live for many years is more likely to be a settled business or residential line, whereas a very recently-allocated block is more commonly seen in VoIP and virtual-number services — the kind sometimes used for short-lived marketing or scam campaigns.
Is a KCOM number safe to answer? In most cases, yes — the overwhelming majority of calls from any UK provider's range are ordinary, legitimate calls. However, two things are important to understand. First, because KCOM can sub-allocate or resell its numbers, the fact that a number sits in a KCOM block does not mean KCOM itself is calling you. Second, UK caller IDs can be spoofed: scammers can make a call appear to come from a KCOM number they don't control. So treat the number as a clue, not proof — judge the call on what the caller actually asks for.
If a KCOM number called you and you're unsure, don't share security details, bank information or one-time passcodes, and don't return the call until you've verified it independently. You can block the specific number on any UK smartphone from the recent-calls list, enable free network-level call screening through your own landline provider, and register with the Telephone Preference Service (TPS) to cut legitimate marketing calls. Persistent nuisance calls can be reported to Ofcom, and suspected scams to Action Fraud (or Police Scotland on 101).

FAQs about KCOM numbers
Is a KCOM number safe to answer?
A KCOM number is usually a normal, legitimate UK line — KCOM is an Ofcom-licensed fixed-line network operator. But because numbers can be resold and caller IDs can be spoofed, you should still judge each call on its content: hang up on anyone who pressures you, asks for security details or one-time passcodes, or wants remote access to your device.
Does a KCOM number mean KCOM is calling me?
Not necessarily. KCOM allocates numbers to its own customers and often sub-allocates ranges to resellers and downstream providers, so the organisation actually calling you may be a completely different business using a KCOM-allocated number. Number spoofing can also make an unrelated caller appear to use a KCOM number.
How many UK numbers does KCOM have?
KCOM currently holds 427 Ofcom-allocated number blocks in our copy of the National Telephone Numbering Plan. Each block typically covers 1,000 or 10,000 individual numbers, so the real count of usable numbers is far higher.
How do I block and report a KCOM number?
On most UK smartphones, open your recent calls, tap the number and choose 'Block this caller'. UK landline providers (BT, Sky, TalkTalk, Virgin Media) offer free call screening you can switch on in their app. Report nuisance calls to Ofcom, scam calls to Action Fraud, and forward scam texts free to 7726. You can also register with the TPS at tpsonline.org.uk to stop legitimate marketing calls.
