Dialing London from Another Country
Britain runs a closed numbering plan, so the area code stays part of the number.
Exit Code
Punch in 011 from the US or 00 from the EU. On a mobile or VoIP line, a simple + does the same job.
UK Code (+44)
Enter 44, the dialing code assigned to the United Kingdom.
London Code (20)
Enter 20.
⚠️ Leave off the leading zero. Never dial 020 here.

London Dialing Questions
Does 0207 beat 0208?
Not really. Both are ordinary London numbers. That said, 0207 has long pointed to central London, so some firms favor it for the prestige.
What is the time in London right now?
Through winter London keeps GMT (Greenwich Mean Time), and in summer it shifts to BST (British Summer Time, GMT+1). Check the gap before you ring business contacts.
Will this code reach London mobiles?
No. The 020 code belongs to London landlines. UK mobiles sit on their own prefixes, usually 07, and are not pinned to any one city.
