01668 — Bamburgh
The 01668 dialling code covers Bamburgh in Northumberland. Below are the currently-allocated Ofcom number ranges and the Range Holders they are assigned to.
About the 01668 dialling code
01668 is the UK area code for Bamburgh and the surrounding Northumberland area, listed in Ofcom’s National Telephone Numbering Plan. When a UK landline calls you and the number begins +44 1668 the originating exchange is most likely physically located in or near Bamburgh. Numbers in this code are allocated to UK communications providers in 1,000- or 10,000-number blocks; the table below shows which Range Holder Ofcom assigned each block to.
This is the same data Ofcom publishes every Wednesday in the public UK Numbering Data feed. We re-ingest the snapshot weekly, so the allocations you see here are at most seven days old. Because UK numbers are portable, the current carrier of any specific number on 01668 can differ from the Range Holder shown — see Range Holder vs current provider for the full explanation.
To identify a specific 01668 number, paste it into the lookup form above. You will see the Range Holder, the allocation status, the area-code metadata for Bamburgh, and a live AI internet check summarising any public web reports about that exact number — useful when an unfamiliar 01668 caller turns out to be a legitimate local business, a national contact-centre, or a scam.
The 01668 code uses standard UK landline call charging: from a UK landline or mobile, the call is billed at the rate set by the caller’s own provider, with most consumer tariffs bundling UK-to-UK landline minutes into a monthly inclusive allowance. It is a geographic number under the Ofcom numbering plan, which means the recipient pays nothing to receive the call, and the caller pays a normal landline rate regardless of where in the UK they are dialling from. International callers should drop the leading zero and dial +44 1668 followed by the local number.
01668 numbers can be reached as a UK consumer landline, used by a small business operating from Bamburgh, allocated to a national contact-centre that wants a Bamburgh-presenting CLI, or provisioned to a VoIP service whose subscriber lives anywhere in the UK. Because the same code can fan out to such different real-world callers, the dialling code on its own is rarely enough to identify who is calling. The combination of (a) the Ofcom Range Holder for the specific block, (b) the public web reputation surfaced by the AI internet check, and (c) the call’s context (time of day, whether you were expecting a call, what they ask for) is what actually answers who called me from 01668?
01668 by the numbers
The 01668 dialling code currently has 200 allocated number ranges on file across 53 distinct Ofcom Range Holders. The largest holder by allocated block count is BT with 4 ranges, followed by GCI Network Solutions Limited (4) and Magrathea Telecommunications Limited (2). Numbers in this area are predominantly recorded as Allocated (55% of the visible blocks), with Protected accounting for a further 42%. The allocated prefixes on 01668 run from +44 16680 through +44 1668510, which Ofcom carves into 6 distinct block roots in the table below.
Of those visible blocks, 55% are in active Allocated status; the rest are a mix of Designated (earmarked for a specific use but not yet released), Reserved (held back from the general pool), Quarantined (recently freed and not yet eligible for re-issue), and Free (available for re-allocation). The mix matters when you’re trying to identify a caller: a number sitting inside an Allocated 01668 block is in active service with a UK customer, whereas a number claimed to be from a Designated or Reserved block almost certainly isn’t the genuine origin and points instead at a spoofed CLI worth treating with caution.
By number family, the visible 01668 blocks are mostly geographic (01 / 02) (100%) — a useful sanity check, because a geographic code should be dominated by geographic ranges, and any large non-geographic share would be a sign the block boundaries are worth a closer look.
Best practice when a 01668 call comes in
- Cross-reference the digits against the Range Holder column below — a call presenting a 01668 CLI that doesn’t reconcile to one of the UK-licensed providers listed is the first amber flag.
- Treat the prefix as one signal, not the whole story. UK numbers are portable, and any geographic code can be CLI-spoofed through an offshore VoIP gateway, so the 01668 root only narrows the field of likely callers.
- Paste the exact digits into the lookup form above for a live AI internet check — if a 01668 number has been logged on consumer scam-reporting forums, that surfaces alongside the Range Holder record.
- If a 01668 caller pressures you for payment details, account credentials or remote-access permission, hang up. Find the official number on the organisation’s website or a recent statement and ring back yourself rather than trusting the incoming CLI.

FAQs about 01668
What does the 01668 area code cover?
01668 is the UK dialling code for Bamburgh and the wider Northumberland area. When you receive a call starting with 01668 from a UK landline, the originating exchange is likely in or near Bamburgh, although Ofcom number portability means a customer can keep a 01668 number after moving elsewhere in the UK.
Is a 01668 number safe?
Most calls from 01668 are legitimate landlines belonging to local residents, businesses or contact centres operating from the Bamburgh charging area. Scammers can, however, spoof any UK area code from a VoIP gateway anywhere in the world, so a 01668 prefix alone does not prove the caller is genuinely in Bamburgh. Use the lookup above to see the Range Holder for the specific number, then read the AI internet check for behavioural reports — the risk score plus public forum reports are stronger evidence than the prefix alone.
How many providers operate 01668 number ranges?
Across the 200 ranges currently visible for 01668, 53 different Ofcom Range Holders are listed. The top allocations on this code are typically held by Openreach (BT), Virgin Media O2, and Sky Telecommunications Services, with additional blocks held by Gamma Telecom, Vonage, and a long tail of regional carriers. The full table further down this page shows every block in turn.
How do I dial a 01668 number from abroad?
Dial your country’s international access prefix (00 from most of Europe, 011 from North America), then 44, then the 01668 number with the leading zero dropped. For example a Bamburgh 01668 number would be reached as +44 1668-XXX-XXXX. The leading zero used inside the UK is a national-significant prefix and is replaced by the +44 country code when calling internationally.
What's the difference between 01668 and a mobile number?
01668 is a geographic dialling code anchored on Bamburgh; numbers in this range are landlines (or VoIP services that have been allocated a geographic number). UK mobile numbers all start with 07 and are not tied to any geographic area. Calls from a 01668 landline are charged at the recipient’s standard landline rate; mobile-originated calls have separate inclusive-minute rules in most consumer tariffs.
