Post Office Preferred envelopes sold in Australia have four boxes in the bottom right corner of the front of the envelope. These boxes or squares, which Australia Post calls postcode squares, have the postcode for hand-addressed mail, for Australia Post's automated mail-sorting equipment, which uses optical character recognition software. Postcode squares were introduced in 1990.
Australia Post says that postcode squares should not be used for machine-addressed mail, or mail going overseas.

Famous quotes containing the word squares:
“And New York is the most beautiful city in the world? It is not far from it. No urban night is like the night there.... Squares after squares of flame, set up and cut into the aether. Here is our poetry, for we have pulled down the stars to our will.”
—Ezra Pound (1885–1972)
