Serbian ID check
Check a JMBG, a PIB or a bank account number. If one fails, you see which part is wrong and why. Developers can generate valid numbers for testing.
Nothing leaves this page. Every check runs in your browser. What you type is never saved or sent anywhere, and it is gone when you close the tab.
JMBG
The unique master citizen number: 13 digits for the birth date, the registration area, sex and serial number, and a control digit.

PIB
The tax identification number of companies and entrepreneurs: 9 digits, a registration number and a control digit. A person's PIB is their JMBG.
Test data Made up here and valid by the rules. It could still match a real number by chance, so use it for testing only.
Bank account number
18 digits: the bank's code (3), the account (13) and a control number (2). The short form with dashes works too, such as 840-742221843-57.
