How To Call On UK Landlines From The US?

If you are making a direct call on UK Landlines from the US, you must follow the standard UK phone number format. This dialing format is the same for landline numbers and mobile numbers.

Follow these steps for dialing England from the USA:

Step 1: Dial the country’s exit code

The first thing you need to do to call the UK from the US or connect the UK-based people from the US is to dial the US’s exit code– 011.

Each city in the United Kingdom has its own area code, which you must enter after dialing the country code. However, keep in mind that even though the area code includes a 0, you do not need to dial it; simply enter the rest of the digits.

For Example: If you want to connect from Austria from your Austria virtual phone number to London, then the area code is 020, but you must enter only 20, i.e., +011-44-20, right now.

Step 4: Enter the phone number

The fourth and final step in the “How to call London from the US” guide is to enter the phone number. After entering all the codes, dial the last portion of the number– the landline number. Note that the typical UK landline number consists of 10 digits.
