CR2 6XH, 5432, 69008 and A65 F4E2 are examples of the variety of postal codes found around the world. Some countries, such as Australia and France, use fully numeric postal codes. Other countries, such as the United Kingdom and Ireland, use codes that are a combination of letters and numbers.
Australia's postal codes are always four digits long. The first digit of a postal code specifies the destination state. For example, the 5 in postal code 5432 tells the post office that the delivery goes to South Australia. French postal codes are five digits long, with the first two digits identifying the destination province. For example, the 69 in 69008 tells the post office that the delivery goes to the Rhone-Alpes province.
Postal codes in the United Kingdom use letters and numbers and are between six and eight characters long. Examples include CR2 6XH and M1 1AE. Ireland uses postal codes that are seven characters long, such as A65 F4E2. In both of these countries, the characters before the space identify the general area or town to which the delivery is addressed, while the characters after the space specify the destination neighborhood or address.
