Dialing London Numbers

Dialing a London number requires you to follow a specific format, depending on where you are calling from. Here's a breakdown:

• Within London: If you're calling a London number from another London number, simply dial the 8-digit phone number. The area code (020) is not necessary in this case.
• From Elsewhere in the UK: If you are calling a London number from outside of London but within the UK, you need to dial the area code (020) followed by the 8-digit phone number. For example, to call a number in London, you would dial 020 XXXXXXXX.
• From Outside the UK: If you are calling a London number from outside the UK, you need to dial the international dialing code for the UK (+44), followed by the area code (without the leading zero) and the 8-digit phone number. For example, to call a London number, you would dial +44 20 XXXXXXXX.
