Can the social security card be used after it has not been activated for more than one year?

Can't use it. If the new social security card is not activated within 6 months after receiving the card, its use will be restricted. The social security card holder shall activate the social security card within 6 months after receiving the card, during which the medical insurance card can still be used normally. After activating the social security card, the original medical insurance card will automatically become invalid. If it is not activated within the time limit, the use of the original medical insurance card will be restricted.
