Frequently asked questions
+Are these real UK phone numbers?
No. These are randomly generated numbers that follow valid UK phone number formats using real area codes. They are not assigned to any real person or business.
+What format do UK phone numbers use?
UK landline numbers are 10 digits starting with 0 (e.g. 020 for London, 0161 for Manchester). When dialling internationally, drop the leading 0 and add +44. Mobile numbers start with 07 and are also 11 digits in total.
+What is the difference between UK landline and mobile numbers?
UK landlines use geographic area codes such as 020 (London) or 0121 (Birmingham). Mobile numbers always start with 07 (e.g. 07700, 07800) and are not tied to a specific region.
