Why is my start/end address or postcode not recognised?
The most accurate way to get directions is to use a postcode to postcode search, as the postcodes indicate exact start and end points. If the way in which the address is entered differs even slightly from the way in which we have that address stored in our database, the system will not recognise it, but it should provide you with a choice of options. If the address is still not recognised, you may find the Royal Mail site useful here.
