Who called me from a Home Office number?
Home Office is a UK communications provider. Look up any of its 1 Ofcom-allocated number blocks below.
Home Office is a UK communications provider. That means Ofcom has allocated Home Office one or more blocks of UK telephone numbers under the National Telephone Numbering Plan, which Home Office can either use for its own customers or sub-allocate to resellers and downstream providers. In total, Home Office currently holds 1 allocated number block in our copy of the Ofcom plan.
Home Office's number ranges are concentrated in 073. Across all of its allocations the split is roughly 1 mobile block. You can use the tables below to jump straight to a specific Home Office area code or number block and see the common call patterns reported for it.
The oldest Home Office number block in the Ofcom data was allocated in 2016. 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 Home Office 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 Home Office can sub-allocate or resell its numbers, the fact that a number sits in a Home Office block does not mean Home Office itself is calling you. Second, UK caller IDs can be spoofed: scammers can make a call appear to come from a Home Office 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 Home Office 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 Home Office numbers
Is a Home Office number safe to answer?
A Home Office number is usually a normal, legitimate UK line — Home Office is an Ofcom-licensed communications provider. 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 Home Office number mean Home Office is calling me?
Not necessarily. Home Office 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 Home Office-allocated number. Number spoofing can also make an unrelated caller appear to use a Home Office number.
How many UK numbers does Home Office have?
Home Office currently holds 1 Ofcom-allocated number block 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 Home Office 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.
