The Identification Number for Social Security (INSS) in Belgium

The INSS is used to identify a person within the Belgian social security system. You can find this number in the top right corner of the SIS card. An SIS card (Social Information System) is issued to every socially insured person who is a member of a Belgian health insurance fund. The chip card contains a person’s identification data.

其实就是国民身份号码。身份证上就有。

哦, 明白了,
还有 TAX NUMBER是哪个, 在工资单上看到 几个 都不确定 有个reference 号是嘛 ?

Tax number应该是自雇者才有的税号吧?
