What is Area Code 021?

Area code 021 is the telephone area code for Jakarta, the capital city of Indonesia. This area code is used for both landlines and mobile phones within the Jakarta metropolitan area, which includes the cities of Jakarta Utara (North Jakarta), Jakarta Pusat (Central Jakarta), Jakarta Selatan (South Jakarta), Jakarta Barat (West Jakarta), and Jakarta Timur (East Jakarta).

Why is 021 so significant?

  • High Population Density: Jakarta is one of the most populous cities in the world, and the 021 area code reflects its large population and high concentration of phone lines.
  • Economic Center: Jakarta is the economic and financial hub of Indonesia, meaning businesses and individuals need access to reliable phone services.
  • Cultural Significance: As the capital, Jakarta holds a significant place in Indonesian culture and society. Its area code has become synonymous with the city's identity and importance.

Beyond 021: Other Area Codes in Jakarta

While 021 is the most well-known area code for Jakarta, it is not the only one. As Jakarta expanded, additional area codes were introduced to accommodate the growing number of phone lines. These include:

  • 022: Used for the city of Tangerang, which is located adjacent to Jakarta.
  • 0251: Used for Bogor, another city located near Jakarta.

A Historical Note:

Before the implementation of area codes in Indonesia, phone numbers in Jakarta used a single digit prefix, such as 3 or 5. With the introduction of area codes in the 1990s, the 021 prefix became a standard identifier for Jakarta phone numbers.


The 021 area code remains an important symbol of Jakarta's status as the capital and economic powerhouse of Indonesia. It represents the city's vibrant population, bustling business sector, and significant cultural role.
