Now I am curious .. wondering out aloud if countries insist upon anything other than traditional alphanumeric characters? 

From memory in London, the two letters at the end of the postcode numbers were only used to help divide up the mail for the postal delivery routes. Nothing special but I may be wrong.

Also in the '0' region are New Jersey (non-contiguous with the remainder of the '0' area), Puerto Rico, the US Virgin Islands and APO/FPO military addresses for personnel stationed in Europe, Africa, Southwest Asia and aboard vessels based in the waters adjoining those lands; APO/FPO addresses are also used by U.S. diplomatic and consulary facilities. The lowest ZIP code is in Holtsville, New York (00501, a ZIP code exclusively for the U.S. Internal Revenue Service center there).

My kids thought to toss him a wild one by shouting out our postcode. He grinned and politely asked if there were Australian. When they indicated yes he grinned and after a moments hesitation, correctly quoted the name of our suburb. Later as he counted coins from his cat-in-the-hat prop he explained that Australians made it really easy to memorise postcodes with some basic rules and algorithms that have already been mentioned.
