01793 area code — Swindon

01793 is Ofcom's Swindon numbering area, in Wiltshire, South West England. Its exchange town is in Swindon. From abroad, drop the 0 and dial +44 1793.

Traditionally not from another 01793 landline, but it now depends on your provider: Ofcom stopped requiring providers to offer local (code-free) dialling on 11 March 2022. Dialling 01793 first always works, and mobiles always need it.

Numbers on 01793 use Ofcom's 4+6 format: the 5-digit code (including the leading 0) followed by a 6-digit local number — written like 01793 234 567. From abroad the leading zero is dropped: +44 1793 then the local number.

01793 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 0793. Old signage or stationery showing 0793 refers to the same Swindon numbers.

Ofcom lists 89 providers with allocated blocks on 01793. The largest are BT with 172 of the 404 allocated blocks, Vodafone with 28 of the 404 allocated blocks and Gamma Telecom Holdings Limited with 25 of the 404 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 01672 Marlborough (16 km), 01367 Faringdon (17 km), 01285 Cirencester (22 km) and 01666 Malmesbury (23 km).

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.
