Wales is the third biggest country in the United Kingdom, in both the population and surface area. It’s not as sparsely populated as Scotland, but at the same time not as densely packed as England. As with other parts of the United Kingdom, landlines have assigned area codes that provide information about the specific area they are located in. Similarly, with the rapid development of cell phones and various internet based communication channels, the importance and use of landlines has been diminishing, but they are still a valid and important part of communication. Using this page, either by entering the location you want to look up or by using the map, you will get all the information you need about area codes in Wales.
