How can a person have two social security numbers?

Legal analysis: 1, a citizen has two social security numbers, which may be because multiple payments are not from the same company and have not been transferred. The social security account number is identified by the ID card. If the ID card is not duplicated, the social security account number cannot be duplicated.

However, because social security is not connected to the internet, social security is paid by regions. Each region will set up a social security account. If a person pays social security in many places, then before retiring in the future, he will transfer the social security in various places to his retirement place, so that retirement benefits can be calculated together.

2. One ID number corresponds to one person, and only one social security computer number can be processed. If you are employed in different units, the unit enrollment information number under the social security computer number will be different.

If the payment status shows that citizens are still paying and have not stopped insurance, they need to transfer social security to the same place. No matter whether citizens are insured and pay social security in their registered residence or non-registered residence, they can eventually move the social security accounts insured in various places back to the social security accounts in their registered residence for merger, without affecting the accumulated payment period.

Legal basis: Article 12 of the Interim Measures for the Administration of Social Insurance Registration in People's Republic of China (PRC). When the payer is dissolved, bankrupt, revoked or merged, it shall apply to the original social insurance registration institution for cancellation of social insurance registration in time.
