Who called me from a Vonage number?
Vonage is a UK communications provider. Look up any of its 140 Ofcom-allocated number blocks below.
Vonage is a UK communications provider, part of Ericsson. That means Ofcom has allocated Vonage one or more blocks of UK telephone numbers under the National Telephone Numbering Plan, which Vonage can either use for its own customers or sub-allocate to resellers and downstream providers. In total, Vonage currently holds 140 allocated number blocks in our copy of the Ofcom plan.
Vonage's number ranges are concentrated in 01753 (Slough), (020) (London), 0121 (Birmingham), 0191 (Newcastle). Across all of its allocations the split is roughly 139 geographic landline, 1 03 non-geographic blocks. You can use the tables below to jump straight to a specific Vonage area code or number block and see the common call patterns reported for it.
The oldest Vonage number block in the Ofcom data was allocated in 2010, and the most recent in 2023. 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 Vonage 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 Vonage can sub-allocate or resell its numbers, the fact that a number sits in a Vonage block does not mean Vonage itself is calling you. Second, UK caller IDs can be spoofed: scammers can make a call appear to come from a Vonage 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 Vonage 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 Vonage numbers
Is a Vonage number safe to answer?
A Vonage number is usually a normal, legitimate UK line — Vonage 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 Vonage number mean Vonage is calling me?
Not necessarily. Vonage 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 Vonage-allocated number. Number spoofing can also make an unrelated caller appear to use a Vonage number.
How many UK numbers does Vonage have?
Vonage currently holds 140 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 Vonage 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.
