The 01556 area code is used for Castle Douglas (Council of Dumfries and Galloway) and the areas directly surrounding Castle Douglas, which includes 11 distinct locations. Most 01556 numbers are used for landlines. However, they can also be purchased by companies or organizations to be used for services that don’t have any connection to the Castle Douglas area.
Previously, the area used 0556 as their area code. This changed in April 1995 during the phONEday event, where it was changed to the 01556 area code to accommodate the growing population and supplement the shrinking supply of phone numbers in Dumfries and Galloway.
