The personal account number is personal information that must be treated responsibly. It may be requested at the pension fund, at work and in some government institutions (hospitals, schools, kindergartens). Police officers cannot ask you for your SNILS - they ask for any identification document of your choice.
Anyone who asks you for your personal account number must fill out a personal data processing application. If this does not happen, there is reason to suspect fraud.
How do scammers find out someone else's SNILS?
Fraudsters always obtain data about individuals by fraudulent means. Let's name some methods:
Information leakage. Sometimes it happens that data is transmitted by unscrupulous employees of financial organizations, private pension funds, and government agencies.
By phone. The fraudster may call from an unknown number, introduce germany mobile database himself as a pension fund employee and request personal information. Not realizing the fraud, the victim gives his SNILS number.
In person. The attacker can go door-to-door on behalf of the Pension Fund and collect personal account numbers in this way.
When collecting signatures. A fraudster can collect signatures in public places - for example, for the preservation of an important historical building. They will collect SNILS numbers (or passports) from all the signatories, and then it will turn out that no one planned to demolish the building and the signatures were collected in order to obtain personal data.
Through fake websites. There are non-governmental sites where you can supposedly find out about the funded portion of your pension. And to register, you need to provide your SNILS, which will eventually be found out by the scammers.
Through fake recruitment agencies. They offer help with finding a job, but in reality they collect personal information and use it for fraud.
