Things to Know Before Calling the US
Before calling the US from the UK, you need to get familiar with three basic terms.
- Time Zone
- Exit Code
- Country Code
- Area Code
Time Zone
Before planning a call to the US from the UK, you need to consider the time zone. Since the US is geographically a vast country, it has different time zones even within the country. Therefore, to avoid any hassle, you must mind the timings of the area where you are calling.
Exit Code
The international access code or the exit code indicates your network that you are trying to make a call outside the UK so that the carrier can shift your call appropriately to your desired network in the US. The exit code of the UK is “00”. If you use a cell phone instead of a landline, you need to press the “+” symbol instead of pressing “00.”
Country Code
The country code is also commonly termed as calling code. Every country has its unique country code, which helps the networks direct the calls only to that specific location. The country code of the United States is 1.
Area Code
Since there are different cities worldwide, the networks require further specifications regarding which city the user wants their call to be connected to. Hence, each city is assigned a unique area code that can vary between two to five digits. The area codes in the US mainly consist of three numbers. So, before you call the US from the UK, having the correct area code is a must.
