About the 01835 dialling code

01835 is the UK area code for St Boswells and the surrounding Scotland area, listed in Ofcom’s National Telephone Numbering Plan. When a UK landline calls you and the number begins +44 1835 the originating exchange is most likely physically located in or near St Boswells. 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 01835 can differ from the Range Holder shown — see Range Holder vs current provider for the full explanation.

To identify a specific 01835 number, paste it into the lookup form above. You will see the Range Holder, the allocation status, the area-code metadata for St Boswells, and a live AI internet check summarising any public web reports about that exact number — useful when an unfamiliar 01835 caller turns out to be a legitimate local business, a national contact-centre, or a scam.

The 01835 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 1835 followed by the local number.

01835 numbers can be reached as a UK consumer landline, used by a small business operating from St Boswells, allocated to a national contact-centre that wants a St Boswells-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 01835?

01835 by the numbers

The 01835 dialling code currently has 200 allocated number ranges on file across 26 distinct Ofcom Range Holders. The largest holder by allocated block count is Vodafone Ltd (C&W) with 11 ranges, followed by VoiceHost Limited (4) and TalkTalk Communications Limited (4). Numbers in this area are predominantly recorded as Protected (68% of the visible blocks), with Allocated accounting for a further 33%. The allocated prefixes on 01835 run from +44 1835 through +44 1835369, which Ofcom carves into 5 distinct block roots in the table below.

Of those visible blocks, 33% 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 01835 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 01835 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 01835 call comes in

  • Cross-reference the digits against the Range Holder column below — a call presenting a 01835 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 01835 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 01835 number has been logged on consumer scam-reporting forums, that surfaces alongside the Range Holder record.
  • If a 01835 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 01835

What does the 01835 area code cover?

01835 is the UK dialling code for St Boswells and the wider Scotland area. When you receive a call starting with 01835 from a UK landline, the originating exchange is likely in or near St Boswells, although Ofcom number portability means a customer can keep a 01835 number after moving elsewhere in the UK.

Is a 01835 number safe?

Most calls from 01835 are legitimate landlines belonging to local residents, businesses or contact centres operating from the St Boswells charging area. Scammers can, however, spoof any UK area code from a VoIP gateway anywhere in the world, so a 01835 prefix alone does not prove the caller is genuinely in St Boswells. 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 01835 number ranges?

Across the 200 ranges currently visible for 01835, 26 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 01835 number from abroad?

Dial your country’s international access prefix (00 from most of Europe, 011 from North America), then 44, then the 01835 number with the leading zero dropped. For example a St Boswells 01835 number would be reached as +44 1835-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 01835 and a mobile number?

01835 is a geographic dialling code anchored on St Boswells; 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 01835 landline are charged at the recipient’s standard landline rate; mobile-originated calls have separate inclusive-minute rules in most consumer tariffs.
