Is it because the company didn't pay the insured account?

This situation is not necessarily that the company has not paid.

There may be many reasons for participating in insurance but not paying: first, it may be that the company did pay social security for its employees, but the information was delayed due to the connection between the banking system and the social security payment system. Generally speaking, the closing time of the bank is 3 working days, and the closing time of the social security system may cause some delay.

It may also be that when employees leave their jobs, the company fails to go through the formalities of social security registration and suspension, and fails to continue to pay social security fees for them, which will also lead to the social security account being in arrears or unpaid.
