What's the impact of having two social security cards?

It doesn't matter if a person has two social security cards.

Because the social security account is unique, the money paid is accumulated in the cancellation of personal accounts. At the same time, no matter how many medical insurance cards you have, if you need to reimburse medical behavior, you can only use one medical insurance identity. It is recommended to use the local medical insurance card in your daily residence, because the medical insurance is limited by geography and used in different places, and the reimbursement rate will be lower. The above information is for reference only. If necessary, it is recommended to consult the local social security department.

Two social security cards can be merged. If two social security accounts are in the same area, you only need to merge the social security accounts, save the social security accounts with the latest information, and merge the other social security account into the new account. If two social security accounts are not handled in the same area, you need to bring your ID card and two social security cards to the local social security bureau to apply for merging social security accounts.

After the social security card is lost or stolen, corresponding measures should be taken to reduce potential risks and inconvenience. First of all, immediately report the loss to the relevant institutions and report the loss of the social security card to prevent others from using it fraudulently. Secondly, go through the formalities in time and get a new social security card. At the same time, pay close attention to the changes in personal social security accounts to ensure that they are not infringed by criminals. In addition, report the case to the public security organ in time, provide relevant evidence and assist the police to trace the suspect. The loss or theft of social security cards may lead to the disclosure of identity information and damage to social security rights and interests.

To sum up, it is very important to take timely measures to protect personal information security and safeguard their own rights and interests.
