01603 Area Code - Norwich

The 01603 area code is used for Norwich (County of Norfolk) and the areas directly surrounding Norwich, which includes 16 distinct locations. Most 01603 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 Norwich area.

Previously, the area used 0603 as their area code. This changed in April 1995 during the phONEday event, where it was changed to the 01603 area code to accommodate the growing population and supplement the shrinking supply of phone numbers in Norfolk.
