If a 01704 number called you
No clear pattern in reports for these numbers yet. If a call worried you:
- 1
Call back on a number you trust
If a caller says they're your bank, HMRC, a courier or a council, hang up and ring the organisation on the number from its website or your statement, never the number that called you. Caller ID can be faked.
- 2
Forward it to 7726
On a mobile, copy the caller's number from your recent calls and text it to 7726 (it spells SPAM). Scam texts can be forwarded to 7726 as they are. It's free, and your network uses the reports to investigate and block numbers.
- 3
Stop sales calls
Register your landline and mobile free with the Telephone Preference Service (0345 070 0707). Legitimate UK marketers must check it; calls should drop within 28 days. It won't stop scammers.
- 4
If you lost money or shared details
Call your bank on the number on your card (or 159 to reach most UK banks safely), then report it to Report Fraud online or on 0300 123 2040. Report Fraud replaced Action Fraud on 4 December 2025 for England, Wales and Northern Ireland; in Scotland call Police Scotland on 101.
01704 history and number format
Number format: Numbers on 01704 use Ofcom's 4+6 format: the 5-digit code (including the leading 0) followed by a 6-digit local number — written like 01704 234 567.
Before 1995: 01704 took its current form at PhONEday on 16 April 1995, when a "1" was inserted into every UK geographic code — before that the area dialled 0704.
Local dialling: Traditionally not from another 01704 landline, but it now depends on your provider: Ofcom stopped requiring providers to offer local (code-free) dialling on 11 March 2022. Dialling 01704 first always works, and mobiles always need it.
Allocation record: the oldest number block still visible on 01704 was allocated on 15 July 1994, and the most recent on 17 March 2026. 2 blocks were allocated in the last 12 months — newly-activated ranges with no call history, which is worth knowing when an unfamiliar 01704 number rings (see the weekly numbering changelog for every new allocation.)

FAQs about 01704
Where is area code 01704?
01704 is Ofcom's Southport numbering area, in Merseyside, North West England. Its exchange town is in Sefton. From abroad, drop the 0 and dial +44 1704.
Do I need to dial 01704 for a local call?
Traditionally not from another 01704 landline, but it now depends on your provider: Ofcom stopped requiring providers to offer local (code-free) dialling on 11 March 2022. Dialling 01704 first always works, and mobiles always need it.
How are 01704 numbers written?
Numbers on 01704 use Ofcom's 4+6 format: the 5-digit code (including the leading 0) followed by a 6-digit local number — written like 01704 234 567. From abroad the leading zero is dropped: +44 1704 then the local number.
What was the 01704 area code before?
01704 took its current form at PhONEday on 16 April 1995, when a "1" was inserted into every UK geographic code — before that the area dialled 0704. Old signage or stationery showing 0704 refers to the same Southport numbers.
Which phone companies hold 01704 numbers?
Ofcom lists 98 providers with allocated blocks on 01704. The largest are BT with 23 of the 176 allocated blocks, Sky UK Limited with 13 of the 176 allocated blocks and GCI Network Solutions Limited with 12 of the 176 allocated blocks. Numbers can be ported, so a number's current provider may differ from the block's holder.

By distance between exchange towns, the nearest other codes are 01695 Skelmersdale (18 km), 01253 Blackpool (20 km), 01257 Coppull (23 km) and 01772 Preston (25 km).
How do I report a scam call from a 01704 number?
On a mobile, text the caller's number to 7726 (free). If you lost money or shared details, call your bank and report it to Report Fraud (0300 123 2040), which replaced Action Fraud in December 2025. Unwanted sales calls go to the ICO after registering with the Telephone Preference Service.
