Understanding the Indonesian Identity Number (IDN)

What is IDN?

The Indonesian Identity Number (Nomor Induk Kependudukan, or NIK) is a unique identification number assigned to citizens and residents of Indonesia. It serves as a vital tool for administrative purposes, linking individuals to governmental services such as healthcare, taxation, and social security.

Structure of IDN

The IDN consists of a 16-digit numerical code structured as follows:

• Digits 1-6: Date of birth (YYMMDD)
• Digits 7-12: Serial number (unique for individuals born on the same date)
• Digits 13-15: Code identifying the province of birth
• Digit 16: Checksum digit for validation

This format ensures that no two individuals share the same IDN, thus enhancing the efficiency of identification systems across the nation.
