Frequently asked questions about eKTP Validator API

What is the standard format and length of the NIK input?

The National Identification Number (NIK) must consist of exactly **16 digits**. It is a unique, lifelong identifier issued to Indonesian residents, structured based on regional codes (province, regency/city, sub-district), date of birth, and a sequential registration number.

How are gender and birth dates encoded within the 16-digit NIK?

The 16 digits of a NIK are structured as follows: * **Digits 1–2:** Province code * **Digits 3–4:** Regency/City code * **Digits 5–6:** Sub-district code * **Digits 7–12:** Date of birth in the format `DDMMYY`. Note that for females, 40 is added to the day value (e.g., `57` instead of `17`). * **Digits 13–16:** Sequential registration number starting from `0001` (managed to differentiate residents with identical birth dates and domiciles).
