Dial London Cheaply No Matter Where You Are
Follow these simple steps to put London numbers into international format and lock in low per minute pricing. We also point out the usual mistakes worth avoiding with UK numbers.
Start with +44
Begin with the plus sign, or your local exit code, followed by 44. That sends the call into the UK. From a mobile, the + sign on its own does the job.
Use 20 for London
After +44, add the London area code 20 and then the 8 digit local number. As an example, +44 20 7123 4567.
Keep mobile codes separate
UK mobiles start with 07. When you call from abroad, remove that zero and dial +44 7 instead. Landlines and mobiles use their own formats.

Mobile Prefixes

A Bit of London Landline History
You might still come across 0207 and 0208 in older listings. Those are legacy subcodes. These days every London landline runs on 020 plus the 8 digit number. If you are unsure, go with +44 20 followed by the local number.
