ISO 3166-2:PK designates the code entry for Pakistan within ISO 3166-2, a component of the broader ISO 3166 standard developed and maintained by the International Organisation for Standardisation (ISO). This standard establishes alphanumeric codes representing principal administrative subdivisions—including provinces, states, and territories—of nations enumerated in ISO 3166-1.
At present, Pakistan-specific codes encompass one federal capital territory, four provincial jurisdictions, and two areas under Pakistani administration [VERIFY: Total count reflects current territorial configuration]. The Islamabad Capital Territory houses the national capital of Islamabad and possesses constitutional status equivalent to provincial entities.
Each designation comprises two constituent segments joined by a hyphen. The initial segment consists of PK, representing the ISO 3166-1 alpha-2 country code for Pakistan. The secondary segment typically employs two alphabetic characters.
