Why is it wrong that my social security number is 10 and the school says it must be more than 8 digits? I went to the social security bureau to check these ten digits, that's right. Solve it.

I paid it before, and the social security number still has seven digits. If the local social security number is adjusted, there will be corresponding adjustment policies. For example, in Guangzhou, the original number was 8. Add 10 in front of it to make ten. If there are seven people, add 100 to make ten people.
