Maidenhead's telephone numbers all start 01628.
Some old publications may still show an 0628 number, this was changed to 01628 on "PhOne Day" in 1995. On this day all UK geographical numbers had a 1 inserted after the initial 0.
All Maidenhead numbers are now six-figure, i.e. 01628 nnnnnn. Some old publications still show five-figure numbers. In this case a 6 is required at the beginning of the old 5-figure local number, i.e. 01628 6nnnnn. Five-figure numbers were changed in the second half of 1997.
Neighbouring exchanges include Reading (0118), Bracknell (01344), High Wycombe (01494), Slough/Windsor (01753) and Uxbridge (01895).
