If a 01428 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.
01428 history and number format
Number format: Numbers on 01428 use Ofcom's 4+6 format: the 5-digit code (including the leading 0) followed by a 6-digit local number — written like 01428 234 567.
Before 1995: 01428 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 0428.
Local dialling: Traditionally not from another 01428 landline, but it now depends on your provider: Ofcom stopped requiring providers to offer local (code-free) dialling on 11 March 2022. Dialling 01428 first always works, and mobiles always need it.
Allocation record: the oldest number block still visible on 01428 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 01428 number rings (see the weekly numbering changelog for every new allocation.)

FAQs about 01428
Where is area code 01428?
01428 is Ofcom's Haslemere numbering area, in Surrey, South East England. Its exchange town is in Surrey. From abroad, drop the 0 and dial +44 1428.
Do I need to dial 01428 for a local call?
Traditionally not from another 01428 landline, but it now depends on your provider: Ofcom stopped requiring providers to offer local (code-free) dialling on 11 March 2022. Dialling 01428 first always works, and mobiles always need it.
How are 01428 numbers written?
Numbers on 01428 use Ofcom's 4+6 format: the 5-digit code (including the leading 0) followed by a 6-digit local number — written like 01428 234 567. From abroad the leading zero is dropped: +44 1428 then the local number.
What was the 01428 area code before?
01428 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 0428. Old signage or stationery showing 0428 refers to the same Haslemere numbers.
Which phone companies hold 01428 numbers?
Ofcom lists 90 providers with allocated blocks on 01428. The largest are BT with 12 of the 136 allocated blocks, Barritel Limited with 8 of the 136 allocated blocks and Gamma Telecom Holdings Limited with 8 of the 136 allocated blocks. Numbers can be ported, so a number's current provider may differ from the block's holder.
Which area codes are next to 01428?
By distance between exchange towns, the nearest other codes are 01252 Aldershot (18 km), 01730 Petersfield (18 km), 01483 Guildford (19 km) and 01420 Alton (19 km).
How do I report a scam call from a 01428 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.
