The Beginning of the 01491 Area Code
Prior to the PhONEday event in April 1995, the area code was 0491 and the historic mnemonic code was HY1, with the first two characters taken from the letters H and Y in HenleY-on-thames. On an old rotary dial telephone, this code would have been entered by dialling the numbers 4, 9, and 1.
