Ashford is a town in the county of Kent, England. It lies on the River Great Stour at the south edge of the North Downs, about 61 miles (98 km) southeast of central London and 15.3 miles (24.6 km) northwest of Folkestone by road. The name comes from the Old English æscet, indicating a ford near a clump of ash trees.
It has been a market town since the 13th century, and a regular market continues to be held.
Ashford has been a communications hub and has stood at the centre of five railway lines since the 19th century. The arrival of the railways became a source of employment and contributed to the town's growth. With the opening of the international passenger station it is now a European communications centre, with new lines running between London and the Channel Tunnel (via High Speed 1). The M20 motorway also links Ashford to those two destinations for road traffic.
Ashford was allocated the number 31 numeral in the PO lists
