- have a minimum size of 400mm deep x 270mm wide x 270mm high, with a flag fitted to indicate mail is awaiting collection.
- provide access by a front-opening, non-locking hinged door, facing off the road and fitted with a posting aperture large enough for medium letters to be placed inside without opening the door. The aperture should be no less than 125mm x 25mm
- have the street/road number of your property (if available) clearly printed on the box in numerals at least 25mm high
If your letterbox does not meet the above specification then your Rural Post owner/driver can refuse to deliver or collect your mail. However, most of the owner drivers are far more accommodating and will usually deliver to anything that just about resembles a letter box. They will even sell you a stamp!
I particularly like these two letter boxes that are to be found in rural Canterbury.
