01707 Area Code - Welwyn Garden City

The 01707 area code is used for Welwyn Garden City (County of Hertfordshire) and the areas directly surrounding Welwyn Garden City, which includes 4 distinct locations. Most 01707 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 Welwyn Garden City area.

Previously, the area used 0707 as their area code. This changed in April 1995 during the phONEday event, where it was changed to the 01707 area code to accommodate the growing population and supplement the shrinking supply of phone numbers in Hertfordshire.
