The reason why paying medical insurance shows abnormal registration information may be because it is the first time for you to pay medical insurance, and you must go to the local social security bureau to register information for the first time before you can pay online. If it is not the first time to apply for insurance, you need to consult the competent tax authorities to see if the insurance registration information has been successfully delivered. If it is not delivered successfully, you need to contact the local community and the medical insurance department to deliver it again.
