01438 Area Code - Stevenage

The 01438 area code is used for Stevenage (County of Hertfordshire) and the areas directly surrounding Stevenage, which includes 10 distinct locations. Most 01438 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 Stevenage area.

Previously, the area used 0438 as their area code. This changed in April 1995 during the phONEday event, where it was changed to the 01438 area code to accommodate the growing population and supplement the shrinking supply of phone numbers in Hertfordshire.
