Common Questions

What is the difference between +44 and 0044?

They are the same. '+' is the universal international prefix for mobile phones, while '00' is the standard exit code for many countries (but NOT the USA). From the USA, you dial 011 44, which is the same as +44.

Why does the London area code look like 0207 or 0208?

The official area code for London is just 020. The following digit (7, 8, 3, etc.) is actually part of the local phone number, though people often group them together out of habit. When dialing from the US, dial +44 20 followed by the rest of the number.

How much does it cost to call a UK mobile from USA?

Calling UK mobiles is often more expensive than landlines with traditional carriers. However, StartACall offers very competitive rates for UK mobile numbers (O2, EE, Vodafone, Three) compared to AT&T or Verizon.

Do I need to dial 1 before the number?

No. '1' is the country code for the USA/Canada. When calling the UK, you use '44'. Do not dial 1 before 44.

Calling United Kingdom from United States: what to know

United Kingdom answers on the country code +44, with the capital in London and most business concentrated around London, Manchester and Birmingham. The working language for business is English, and local offices generally keep hours of 9:00 to 17:30 typical. Pub-and-lunch culture clusters meetings 10:00 to 12:30 and 14:00 to 16:30.

From United States the outbound access code is 011, so a manual dial reads 011 then +44 then the local number. StartACall removes that step: the call goes through your browser, so there is nothing to install and no SIM card to swap when you travel between United States and United Kingdom.

Most mobiles in United Kingdom sit on operators such as EE (BT Group), O2 (Virgin Media O2), Vodafone UK. 070 numbers look like UK mobiles but are 'personal numbers' that can cost the caller Β£0.50/minute or more, they're not real mobile lines.

United Kingdom runs on UTC, and it shifts for daylight saving, so confirm the current difference before an early or late call.
