# What airport is CGK?

**CGK is: Soekarno-Hatta International Airport**

Jakarta, Indonesia

## Why the code is CGK

CenGKareng, the district it sits in — nothing to do with Jakarta, Soekarno or Hatta.

The airport authority or a contemporaneous record states this directly.

## The airport

- **IATA code:** CGK
- **ICAO code:** WIII
- **Airport:** Soekarno-Hatta International Airport
- **City:** Jakarta, Indonesia
- **Code origin:** Documented

One of the least guessable major codes: neither the city name nor the airport name appears in it. Jakarta as a city carries JKT. The airport is named for Indonesia's first president and vice-president, and sits in Cengkareng, Tangerang.

## The other code, WIII

Every airport has two codes. The three-letter IATA code, CGK, is the one on your boarding pass and your luggage tag, and it is assigned for commercial use. The four-letter ICAO code, WIII, is the one pilots and controllers use, and it is assigned geographically: the first letter or two identify the region, so every airport in the same part of the world shares a prefix. That is why WIII looks nothing like CGK.
