Guidelines for numbering of buildings

New streets

All new streets should be numbered with:

• odd and even numbers on opposite sides, except for cul-de-sacs, which are usually numbered in order (clockwise)
• numbers in consecutive order without any missing

New buildings 

All new buildings should be numbered with:

• the main entrance used to work out which street it's on (manipulation of numbering to get a different address is not accepted)
• a different number that does not exist on that street
• not use punctuation except for the abbreviation of St, Saint
• not use numbers within the name of a building or street

For buildings with more than one flat or occupancy, numbers must:

• go in a clockwise direction (if this is not possible contact the local sorting office)
• be used externally, not letters, for example, Flat 2, 21 Smith Street (not Flat A, 21 Smith Street, and not 21A Smith Street)
• have a letter added if, for example, 1 property has been made into 4 (A, B, C and D should be added for example)

Private garages 

Private garages and similar buildings used to house cars should not be numbered.
