What materials does the new unit need to renew social security?

Legal analysis: materials to be prepared for transferring to the new company for social security renewal: first, go to the social security agency where the new company is insured to see if the social security agency where the new company is located is willing to accept it. If so, it will issue you a letter of acceptance and other materials. Second, take your ID card to prove the dissolution of labor relations (such as the notice of dissolution of labor contract, you can ask for it from the former unit, and you must give it to the employee after leaving the company. If you don't give it, you can apply for arbitration). Third, take the letter of introduction and personal account file of employee's basic pension relationship transfer to your current employer, which will be handled by the personnel Commissioner of the current employer.
