SYNOPSIS

10
11           while (<>) {
12               /^$RE{zip}{Netherlands}$/   and  print "Dutch postal code\n";

DESCRIPTION

16       Please consult the manual of Regexp::Common for a general description
17       of the works of this interface.
18
19       Do not use this module directly, but load it via Regexp::Common.
20
21       This module offers patterns for zip or postal codes of many different
22       countries. They all have the form "$RE{zip}{Country}[{options}]".
23
24       The following common options are used:
25
26   "{-prefix=[yes|no|allow]}" and "{-country=PAT}".
27       Postal codes can be prefixed with a country abbreviation. That is, a
28       Dutch postal code of 1234 AB can also be written as NL-1234 AB.  By
29       default, all the patterns will allow the prefixes. But this can be
30       changed with the "-prefix" option. With "-prefix=yes", the returned
31       pattern requires a country prefix, while "-prefix=no" disallows a
32       prefix. Any argument that doesn't start with a "y" or a "n" allows a
33       country prefix, but doesn't require them.
34
35       The prefixes used are, unfortunately, not always the same. Officially,
36       ISO country codes need to be used, but the usage of CEPT codes (the
37       same ones as used on cars) is common too. By default, each postal code
38       will recognize a country prefix that's either the ISO standard or the
39       CEPT code. That is, German postal codes may prefixed with either "DE"
40       or "D". The recognized prefix can be changed with the "-country"
41       option, which takes a (sub)pattern as argument. The arguments "iso" and
42       "cept" are special, and indicate the language prefix should be the ISO
43       country code, or the CEPT code.
44
45       Examples:
46        /$RE{zip}{Netherlands}/;
47                  # Matches '1234 AB' and 'NL-1234 AB'.
48        /$RE{zip}{Netherlands}{-prefix => 'no'}/;
49                  # Matches '1234 AB' but not 'NL-1234 AB'.
50        /$RE{zip}{Netherlands}{-prefix => 'yes'}/;
51                  # Matches 'NL-1234 AB' but not '1234 AB'.
52
53        /$RE{zip}{Germany}/;
54                  # Matches 'DE-12345' and 'D-12345'.
55        /$RE{zip}{Germany}{-country => 'iso'}/;
56                  # Matches 'DE-12345' but not 'D-12345'.
57        /$RE{zip}{Germany}{-country => 'cept'}/;
58                  # Matches 'D-12345' but not 'DE-12345'.
59        /$RE{zip}{Germany}{-country => 'GER'}/;
60                  # Matches 'GER-12345'.
61
62   "{-sep=PAT}"
63       Some countries have postal codes that consist of two parts. Typically
64       there is an official way of separating those parts; but in practise
65       people tend to use different separators. For instance, if the official
66       way to separate parts is to use a space, it happens that the space is
67       left off. The "-sep" option can be given a pattern as argument which
68       indicates what to use as a separator between the parts.
69
70       Examples:
71        /$RE{zip}{Netherlands}/;
72                  # Matches '1234 AB' but not '1234AB'.
73        /$RE{zip}{Netherlands}{-sep => '\s*'}/;
74                  # Matches '1234 AB' and '1234AB'.
75
76   $RE{zip}{Australia}{-lax}
77       Returns a pattern that recognizes Australian postal codes. Australian
78       postal codes consist of four digits; the first two digits, which range
79       from '10' to '97', indicate the state, although there are exceptions.
80       Territories use '02' or '08' as starting digits. '0909' is the only
81       postal code starting with '09' - this is the postal code for the
82       Northern Territory University). The (optional) country prefixes are AU
83       (ISO country code) and AUS (CEPT code).
84
85       It the past, it was claimed that for postal codes starting with a 0,
86       the leading 0 may be omitted, and up to (and including) version
87       2016060201, the leading 0 was optional. But there doesn't seem be solid
88       evidence the leading 0 is optional. So, we now require there always to
89       be four digit -- unless the "{-lax}" option is given, then a possibly
90       leading 0 is optional.
91
92       Regexp::Common 2.107 and before used $RE{zip}{Australian}. This is
93       still supported.
94
95       If "{-keep}" is used, the following variables will be set:
96
97       $1  The entire postal code.
98
99       $2  The country code prefix.
100
101       $3  The postal code without the country prefix.
102
103       As of version 2016060201, no $4 or $5 will be set.
104
105   "$RE {zip} {Austria}"
106       Returns a pattern which recognizes Austrian postal codes. Austrian
107       postal codes consists of 4 digits, but not all possibilities are used.
108       This pattern matches the postal codes in use. The (optional) country
109       prefixes are AT (ISO country code) and AUT (CEPT code).
110
111       If "{-keep}" is used, the following variables will be set:
112
113       $1  The entire postal code.

115       $2  The country code prefix.
116
117       $3  The postal code without the country code prefix.
118
119   $RE{zip}{Belgium}

121       codes consist of 4 digits, of which the first indicates the province.
122       The (optional) country prefixes are BE (ISO country code) and B (CEPT
123       code).
124
125       If "{-keep}" is used, the following variables will be set:

135       codes consist of four numbers; the first digit indicates the
136       distribution region, the second the distribution district. The
137       (optional) country prefix is DK, which is both the ISO country code and
138       the CEPT code.
139
140       If "{-keep}" is used, the following variables will be set:

147
148       Danish postal codes will not start with 39. Postal codes of the form

150       will not recognize them.
151
152   $RE{zip}{France}
153       Returns a pattern that recognizes French postal codes. French postal
154       codes consist of five numbers; the first two numbers, which range from
155       '01' to '98', indicate the department. The (optional) country prefixes
156       are FR (ISO country code) and F (CEPT code).  Regexp::Common 2.107 and
157       before used $RE{zip}{French}. This is still supported.
158
159       Monaco uses postal codes which are part of the numbering system used by
160       the French postal code system; their numbers start with 980. These
161       numbers are "not" recognized by this pattern.
162

174       postal area, the last three digits a postal district.  The (optional)
175       country prefixes are DE (ISO country code) and D (CEPT code).
176       Regexp::Common 2.107 and before used $RE{zip}{German}. This is still

189       Greenland, uses the Danish postal codes system. Postal codes starting
190       with 39 are reserved for Greenland, and all Greenlandic postal codes
191       start with 39. Except the postal code for Santa. He uses 2412.
192
193       The (optional) country prefix is GL, which is use both as the ISO
194       country code and the CEPT code. Earlier versions used DK as the prefix.

208       even for the province itself. The fourth digit indicates the route, and
209       the fifth a place on the route (0 for small places, alphabetically for
210       the rest).
211
212       Codes starting with 4789 are postal codes for San Marino; they are not
213       recognized by the pattern. Use "$RE {zip} {'San Marino'}" instead.
214
215       The country prefix is either IT (the ISO country code), or I (the CEPT
216       code).

355       5 digits, with an optional 4 digit extension. By default, extensions
356       are allowed, but not required. This can be influenced by the
357       "-extended" option. If its argument starts with a "y", extensions are
358       required; if the argument starts with a "n", extensions will not be
359       recognized. If an extension is used, a dash is used to separate the
