One ID card and two social security cards.

1. On the premise that both ID cards belong to the insured, the insured can go to the local public security bureau with the ID card and household registration book to prove that the two ID cards are the same person and choose to keep one of them as the current ID card.

2. The insured person holds the ID card, the household registration book and the certificate of the local public security bureau, and applies to the social security bureau of the insured place to correct the social security file inconsistent with the current ID card.

3. If the insured person's two ID cards have the same pension insurance period, and the two insured accounts are merged, one of them needs to surrender.

4. If the insured person's two ID cards are insured and paid in different time periods, you can apply to transfer one of the old-age insurance to the old-age insurance account of the current insured place for merger, and the merged old-age insurance will not affect the accumulated payment period of the insured person.

Migration mode: Take ID card and social security card to the service hall of the social security bureau where you moved out, and take the payment certificate to the social security bureau where you are currently insured to merge social security accounts.
