The number
Drop the 0
Drop the leading 0: London's 020 becomes +44 20, a mobile written 07700 becomes +44 7700. The bigger trap is the number itself. UK 0800, 0845, 0300 and 0844 numbers are non-geographic and priced completely differently from each other, and many refuse international calls outright.

02When
When to call
The UK is 5 hours ahead of New York almost all year, with two short windows in spring and autumn where the clocks change on different dates and the gap becomes 4 hours. UK office hours end at lunchtime on the US East Coast.
Banks, HMRC, the NHS and universities, far more than family. This is a corridor where the number dialled is usually institutional, which means a queue and a phone menu at the other end.
03Cost
Basic rates from a US caller ID
Which of those applies is read off the digits you type, so you are never asked to guess whether a United Kingdom number is a landline or a mobile. Services that ask you to pick quote one of these prices and are wrong whenever the guess is.
Per minute in USD from a US caller ID, part of a minute counting as a full one. Rates last changed 8 October 2026. Everything we publish for United Kingdom, or check one number.

05Questions
Common questions
How do I call the United Kingdom from the US?
Dial 011, then 44, then the United Kingdom number. Drop the leading 0: London's 020 becomes +44 20, a mobile written 07700 becomes +44 7700. The bigger trap is the number itself. UK 0800, 0845, 0300 and 0844 numbers are non-geographic and priced completely differently from each other, and many refuse international calls outright. From a browser on Airlophone there is no exit code at all: you type the number starting +44 and the price for that exact number appears before it dials.
What is the country code for United Kingdom?
+44. From the US you dial 011 first to leave the country, so the full string begins 011 44. From the UK and most of Europe the exit code is 00 instead, and from Australia it is 0011.
How much does it cost to call the United Kingdom?
Basic calls to United Kingdom start at $0.07/min for toll-free and service line. From a US caller ID: landline $0.09/min, mobile $0.12/min, toll-free $0.07/min, service line from $0.07/min. Professional adds $0.02/min to paid calls, whether recording is on or off. Connected calls are billed per minute, with part of a minute counting as a full minute. Enter the number to see its exact price before calling.
Can I use my own number as caller ID?
Yes, if the number is eligible. Verify that you control it once, then select it as your Verified Caller ID when you call. Some networks cannot present a number you own on every route, and the dialer confirms that before the call starts.
What is the best time to call the United Kingdom from the US?
The UK is 5 hours ahead of New York almost all year, with two short windows in spring and autumn where the clocks change on different dates and the gap becomes 4 hours. UK office hours end at lunchtime on the US East Coast.
Do I need an app or a SIM card?
No. Airlophone runs in a browser tab, so there is nothing to install and no SIM to buy, and it works the same on a laptop you have borrowed. The person you call needs nothing either: the call arrives on the ordinary phone network, so their phone rings whether it is a landline or a mobile and whether or not they have internet.
