How to Call the United Kingdom from the US

International phone calls can get expensive. It pays (literally) to get it right.



If you need to call someone in the United Kingdom (UK) from a phone in the US, you’ve got a few options.



It’s cost-effective to call them using popular online calling apps like WhatsApp or Skype. These are free options as long as you subscribe to the relevant service. 



You can also use online meeting tools like  Nextiva , Zoom, or Microsoft Teams.



When you need to physically dial a UK number, like when you don’t have an internet connection, making a call to the UK from American phones becomes a little tricker.



In this post, we include instructions for how to call the UK from a US-based phone number , dissect the intricacies of area codes and mobile phones (cell phones), and run through what you can expect to pay.



Calling in the United Kingdom



Like the US, counties and cities have different area codes in the UK. The majority of UK numbers have 11 digits. A minority of phone numbers have 10 digits. There aren’t any special circumstances for these numbers. It’s a matter of legacy number systems.



A standard UK telephone number looks like this in the UK: 01632960345 .



This is commonly broken down into 0 1632 960345 .




0  is the country (UK).



1632  is the area code.



960345  is the unique landline number.




UK dial codes by area



In the table below, you can see that not all UK area codes are the same length.



For example, Aberdeen has the code 1224, but Belfast has 28.



This doesn’t change the length of the overall phone number. It’s simply down to historical numbering systems.



It’s worth noting that the area codes in UK phone numbers exist only to separate the geographical location. You can just dial the full phone number when you call a number.



There’s no need to remember any associated area codes and areas.  It’s standard practice in the UK to list the complete phone number in any directory, advertisement, or online listing.



City Area Code Aberdeen 1224 Belfast 28 Birmingham 121 Blackburn 1254 Blackpool 1253 Bolton 1204 Bournemouth 1202 Bradford 1274 Brighton 1273 Bristol 117 Cambridge 1223 Cardiff 29 Colchester 1206 Coventry 24 Derby 1332 Dundee 1382 Edinburgh 131 Glasgow 141 Gloucester 1452 Huddersfield 1484 Leeds 113 Leicester 116 Liverpool 151 London 20 Luton 1582 Manchester 161 Middlesbrough 1642 Newcastle 191 Newport 1633 Northampton 1604 Norwich 1603 Nottingham 115 Oxford 1865 Plymouth 1752 Portsmouth 23 Preston 1772 Reading 118 Sheffield 114 Southampton 23 Stoke-on-Trent 1782 Sunderland 191 Swansea 1792 Swindon 1793 Wolverhampton 1902 Worcester 1905 York 1904

When to Call the UK



Time zone differences and national holidays are two major factors to consider when dialing a phone number in the UK.



Time zone differences



The whole of the UK runs in the same time zone. So, if you’re calling someone in London, you can be sure they’re in the same time zone as someone in Glasgow or Cardiff.



The UK follows Daylight Saving Time, which has two time zones during the year.



Between the last Sunday in October and the last Sunday in March, the UK follows Greenwich Mean Time (GMT). 



The differences between the US time zones and GMT are outlined below:



US Time Zone Local Time Greenwich Mean Time Difference Eastern Time 12 Noon 5 PM 5 Hours Central Time 12 Noon 6 PM 6 Hours Mountain Time 12 Noon 7 PM 7 Hours Pacific Time 12 Noon 8 PM 8 Hours Alaska Time 12 Noon 9 PM 9 Hours Hawaii Time 12 Noon 10 PM 10 Hours



In the UK, clocks go forward one hour at 1 am on the last Sunday in March and back one hour at 2 am on the last Sunday in October.



The period when the clocks are one hour ahead is called British Summer Time (BST). In 2023, BST is between 26th March and 29th October.



Note this is a different timescale to when the US has daylight savings time. There is a slight overlap period, which makes for slightly amended time differences.



In the US, Daylight Saving Time starts on the second Sunday in March and ends on the first Sunday in November. It can get confusing during the crossover dates, even when you’ve worked with US and UK folks for 15 years.



It’s always best to be aware of when there’s a crossover in Daylight Saving Time. Use  World Time Buddy  if you’re unsure of the exact time during this period.






National public holidays



Expect most businesses, except those with dedicated  24/7 support  functions, to be closed or operate shortened opening times during national holidays.



The United Kingdom has eight standard national holidays.



Public holiday 2023 2024 New Year’s Day Monday 2nd January Sunday 1st January Good Friday Friday 7th April Friday 29th March Easter Monday Monday 10th April Saturday 1st April Early May Bank Holiday Monday 1st May Saturday 6th May Spring Bank Holiday Monday 29th May Saturday 27th May Summer Bank Holiday Monday 28th August Saturday 26th August Christmas Day Monday 25th December Monday 25th December Boxing Day Tuesday 26th December Thursday 26th December



Note that New Year’s Day is awarded as a national holiday on a Monday when 1st January falls on a Saturday or Sunday.



In special circumstances, the UK can add more national holidays. For example, in 2023, Monday, 8th May, was a national holiday due to the coronation of the new king, King Charles III.



There are also some regional holidays to consider.



Scotland



Scotland has an extra national holiday on 2nd January. If New Year’s Day falls on a Saturday or Sunday, Scotland rolls the public holiday back and celebrates the 2nd January national holiday on the 3rd January.



Scotland also observes St Andrew’s Day on 30th November. Again, the national holiday is pushed to the following Monday if the 30th November falls on a Saturday or Sunday.



Northern Ireland



Northern Ireland has an extra national holiday on 12th July, which marks the anniversary of the Battle of the Boyne. If the 12th of July falls on a Saturday or Sunday, the national holiday is pushed to the following Monday.
