The 01245 area code is used for Chelmsford (County of Essex) and the areas directly surrounding Chelmsford, which includes 15 distinct locations. Most 01245 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 Chelmsford area.

Previously, the area used 0245 as their area code. This changed in April 1995 during the phONEday event, where it was changed to the 01245 area code to accommodate the growing population and supplement the shrinking supply of phone numbers in Essex.
