Postal codes were introduced in France in 1972, when La Poste introduced automated sorting.
The postal code (in French, code postal) consists of five digits, the first two digits identifying the département, or outside Europe, in the French Overseas Departments and Territories. The digits 00 are used for Military addresses.
In Paris, the last two digits of the postal code indicate the arrondissement. Prior to 1972, an address in the eighth arrondissement in Paris , would be written as:
