Well-formed

Three formats are accepted (PMK 112/2022 as amended by PMK 136/2023):

15 digits, the legacy format (02.973.675.8-100.600).
16 digits, either 0 followed by the legacy 15 digits, or a NIK for individual residents.
NITKU, 22 digits: the 16-digit NPWP plus a 6-digit business place number.

Functions

Go	TypeScript	Returns
`npwp.Valid(s)`	`npwp.isValid(s)`	Whether `s` is a well-formed NPWP or NITKU
`npwp.Parse(s)`	`npwp.parse(s)`	The fields below
`npwp.To16(s)`	`npwp.to16(s)`	The 16-digit form of any accepted format
`npwp.Format(s)`	`npwp.format(s)`	15 digits in the dotted layout, otherwise digits only
`npwp.Mask(s)`	`npwp.mask(s)`	Last 4 digits visible

Accepted separators: space, . and -.

Parsed fields

Field (JSON)	Present when	Notes
`npwp16`	Always
`npwp15`	Not a NIK	Legacy 15 digits
`nitku`	Input is a NITKU	22 digits
`businessPlace`	Input is a NITKU	Last 6 digits
`isNik`	Always	The 16 digits are a NIK
`taxOffice`	Not a NIK	3-digit tax office code (KPP)
`status`	Not a NIK	3-digit status (`000` = head office)

There is no official check digit for NPWP published by DJP, so NusaIndex checks structure only. New taxpayers since 2024 receive a 16-digit NPWP without a public structure.

Errors

length, charset, nik (16 digits that look like a NIK but are not a valid one), serial.
