Knowing the format of a postal code is essential not only to be able to recognize it within an address or database field, but also as using the postal code correctly will speed up delivery and reduce returns.

Postal code formats are covered by each country chapter. This data is summarized below for all countries covered:

NB: 9 indicates a numeric digit, A a letter.

Strings between square brackets () should be typed exactly as written. Thus for Greenland, (39)99 indicates that all postal codes begin with 39, are four digits long, and the last two digits are numeric.

Where more than one format is given, each format is possible.

(*) Level of coverage

The level of coverage is shown of the following scale, and is a guideline only. For fuller details refer to the appropriate country chapter:

4 = All postal codes are unique point-of-delivery codes or cover approximately equal-sized groups of points-of-delivery

3 = Some postal codes down to point-of-delivery or small groups of points-of-delivery; others to settlement or groups of settlement level

2 =All postal codes cover a settlement, municipality, post office, postal route or larger area

1 = A single postal code covers the whole country/territory.

n/a = no national postal code coverage.

The regular expression flavour used is Perl. The anchors use (\A, \Z) are those for a code being on its own in a field, without padding with spaces.
