How to Call the UK from Ireland?

When calling the UK from Ireland, firstly, you need to understand the relevant dialing prefixes (exit code, country code, and area code). Moreover, it is also important to consider the calling rates to call at a reasonable cost.

Since you are making an international call from Ireland to the UK, you must begin your call with Ireland’s exit code, which is ‘00’. However, the 00 can be replaced by the “+” symbol when calling from a mobile.

The UK’s country code, 44, follows next. Dialing this code instructs your phone network to route the call to the UK.

An area code resembles a specific region, city, or part of a state. In the UK, area codes vary from two to five digits and always start with 0. The 0 is the trunk code and is mandatory when making domestic calls. However, it should be omitted when calling internationally.

Here are some popular United Kingdom cities alongside their area codes.
