NAME

Geo::UK::Postcode - Object and class methods for working with British postcodes.

SYNOPSIS

    # See Geo::UK::Postcode::Regex for parsing/matching postcodes

    use Geo::UK::Postcode;

    my $pc = Geo::UK::Postcode->new("wc1h9eb");

    $pc->raw;             # wc1h9eb - as entered
    $pc->as_string;       # WC1H 9EB - output in correct format
    "$pc";                # stringifies, same output as '->as_string'
    $pc->fixed_format;    # 8 characters, the incode always last three

    $pc->area;            # WC
    $pc->district;        # 1
    $pc->subdistrict;     # H
    $pc->sector;          # 9
    $pc->unit;            # EB

    $pc->outcode;         # WC1H
    $pc->incode;          # 9EB

    $pc->strict;          # true if matches strict regex
    $pc->valid;           # true if matches strict regex and has a valid outcode
    $pc->partial;         # true if postcode is for a district or sector only

    $pc->non_geographical;    # true if outcode is known to be
                              # non-geographical

    $pc->bfpo;                # true if postcode is for a BFPO address

    my @posttowns = $pc->posttowns;    # list of one or more 'post towns'
                                       # associated with this postcode

    # Sort Postcode objects:
    use Geo::UK::Postcode qw/ pc_sort /;

    my @sorted_pcs = sort pc_sort @unsorted_pcs;

DESCRIPTION

An object to represent a British postcode.

For matching and parsing postcodes in a non-OO manner without the Moo dependency (for form validation, for example), see Geo::UK::Postcode::Regex or Geo::UK::Postcode::Regex::Simple.

For geo-location (finding latitude and longitude) see "GEO-LOCATING POSTCODES".

ATTRIBUTES

raw

The exact string that the object was constructed from, without formatting.

METHODS

raw

as_string

    $pc->as_string;

    # or:

    "$pc";

Stringification of postcode object, returns postcode with a single space between outcode and incode.

fixed_format

    my $fixed_format = $postcode->fixed_format;

Returns the full postcode in a fixed length (8 character) format, with extra padding spaces inserted as necessary.

area, district, subdistrict, sector, unit

Return the corresponding part of the postcode, undef if not present.

outcode

The first half of the postcode, before the space - comprises of the area and district.

incode

The second half of the postcode, after the space - comprises of the sector and unit. Returns an empty string if not present.

outward, inward

Aliases for outcode and incode.

valid

    if ($pc->valid) {
        ...
    }

Returns true if postcode has valid outcode and matches strict regex.

partial

    if ($pc->partial) {
      ...
    }

Returns true if postcode is not a full postcode, either a postcode district ( e . g . AB10 ) or postcode sector (e.g. AB10 1).

strict

    if ($pc->strict) {
      ...
    }

Returns true if postcode matches strict regex, meaning all characters are valid ( although postcode might not exist ) .

non_geographical

    if ($pc->non_geographical) {
      ...
    }

Returns true if the outcode is known to be non-geographical. Note that geographical outcodes may have non-geographical postcodes within them.

(Non-geographical postcodes are used for PO Boxes, or organisations receiving large amounts of post).

bfpo

    if ($pc->bfpo) {
        ...
    }

Returns true if postcode is mapped to a BFPO number (British Forces Post Office).

posttowns

    my (@posttowns) = $postcode->posttowns;

Returns list of one or more 'post towns' that this postcode is assigned to.

Post towns are rarely used today, and are no longer required in a postal address but are included with the postcode data, so provided here.

EXPORTABLE

pc_sort

    my @sorted_pcs = sort pc_sort @unsorted_pcs;

Exportable sort function, sorts postcode objects in a useful manner. The sort is in the following order: area, district, subdistrict, sector, unit (ascending alphabetical or numerical order as appropriate).

GEO-LOCATING POSTCODES

Postcodes can be geolocated by obtaining the Ordnance Survey 'Code-Point' data (or the free 'Code-Point Open' data).

For full details of using this class with Code-Point data, see: Geo::UK::Postcode::Manual::Geolocation.
