DESCRIPTION

This module can be used to validate Indonesian taxpayer registration number, Nomor Pokok Wajib Pajak (NPWP).

NPWP is composed of 15 digits as follow:

ST.sss.sss.C-OOO.BBB

S is a serial number from 0-9 (so far haven't seen 7 and up, but it's probably possible).

T denotes taxpayer type code (0 = government treasury [bendahara pemerintah], 1-3 = company/organization [badan], 4/6 = invidual entrepreneur [pengusaha perorangan], 5 = civil servants [pegawai negeri, PNS], 7-9 = individual employee [pegawai perorangan]).

sss.sss is a 6-digit serial code for the taxpayer, probably starts from 1. It is distributed in blocks by the central tax office (kantor pusat dirjen pajak, DJP) to the local tax offices (kantor pelayanan pajak, KPP) throughout the country for allocation to taypayers.

C is a check digit. It is apparently using Luhn (modulus 10) algorithm on the first 9 digits on the NPWP.

OOO is a 3-digit local tax office code (kode KPP).

BBB is a 3-digit branch code. 000 means the taxpayer is the sole branch (or, for individuals, the head of the family). 001, 002, and so on denote each branch.

METHODS

new $str

Create a new Business::ID::NPWP object.

validate()

Return true if NPWP is valid, or false if otherwise. In the case of NPWP being invalid, you can call the errstr() method to get a description of the error.

errstr()

Return validation error of NPWP, or undef if no error is found. See validate().

normalize()

Return formatted NPWP, or undef if NPWP is invalid.

pretty()

Alias for normalize().

taxpayer_code()

Return 2-digit taxpayer code component of NPWP, or undef if NPWP is invalid.

kode_wajib_pajak()

Alias for taxpayer_code().

kode_wp()

Alias for taxpayer_code().

serial()

Return 6-digit serial component of NPWP, or undef if NPWP is invalid.

check_digit()

Return check digit component of NPWP, or undef if NPWP is invalid.

local_tax_office_code()

Return 3-digit local tax office code component of NPWP, or undef if NPWP is invalid.

kode_kpp()

Alias for local_tax_office_code().

branch_code()

Return 3-digit branch code component of NPWP, or undef if NPWP is invalid.

kode_cabang()

Alias for branch_code().

FUNCTIONS

validate_npwp($string)

Return true if NPWP is valid, or false if otherwise. If you want to know the error details, you need to use the OO version (see the errstr method).

Exported by default.
