Dorchester councillor Les Fry, a former police officer, said that during his career trying to find a house in a village in the middle of the night, which only had a name, had been a re-occurring problem.
“Names are frustrating. How do you find Manor Farm or Holly Cottage when you are in a hurry? There should also be a number there.
“Postcodes take you to the area but you need a number after that,” he said.
Cabinet member Cllr Peter Wharf said the lack of logic to addresses was also a cause of ambulances arriving later than they should. He said it also caused occasional problems for gas, electricity and water services as well as delivery by courier companies.
