The second generation social security card has not expired. Can I replace the third generation social security card?

There is no mandatory requirement. Hebei and other places clearly stated that even if the third-generation social security card is not replaced, the second-generation social security card can still be used for a long time. However, it is suggested that if the third-generation social security card has been issued in your area, you can consider replacing it, and it is free for the second-generation social security card to replace the third-generation social security card for the first time. The third-generation social security card is relatively more advanced, convenient and safe.
