What should I do if the postal code of Linyi Smart Society Pension Certification is wrong?

Bring the original ID card to the social security department to explain the situation and re-apply.

If the postal code of the social security card is incorrect, you can go to the social security bureau to change the card again, but the postal code of the general social security card is incorrect, which will not affect the use of your social security card. Residents can also use their social security cards to go to the main hospitals in this area for medical treatment.
