The last company didn't give me a social security renewal card when I left my job, but the new company bought me a social security renewal card! What should I do to connect the card?

First of all, you have to open a certificate in the new company before you can bring your social security to the new company. Then go to the original company and take the social security card to the social security bureau where the original company is located, and let the social security bureau print the payment details for you, so that you can take the social security card fee to the new company for social security. (If you didn't pay the social security in the month from your old company to your new company, you need to pay it yourself! ) I hope I can help you!
