Do I need to change my social security card when I change my work unit?

Legal analysis: Whether changing jobs requires changing social security mainly depends on the specific situation of job changes.

If you just change a company but still work in the local area, you don't need to change your social security card. Because you were originally insured in the local area, you just changed a unit, but the insured place has not changed, so naturally you don't need to change your social security card.

However, if you work in another city, the social security relationship has changed and you need to move to the location of your new unit, and your social security card needs to be replaced. After all, social security belongs to regional overall planning. If you change jobs in a city, the insured institutions are different, and the social security card naturally needs to be replaced.

It should also be noted that many people may pay social security in many places because of job changes. To receive a pension in the future, the place to receive it shall be determined according to the principle of "household registration first, long-term calculation later".

Legal basis: Article 58 of People's Republic of China (PRC) Social Insurance Law. The employing unit shall handle social insurance registration for employees within 30 days from the date of employment. If the social insurance has not been registered, the social insurance agency shall verify the social insurance premium it should pay. Employees-free individual industrial and commercial households who voluntarily participate in social insurance, part-time employees who do not participate in social insurance in the employing unit and other flexible employees shall apply to the social insurance agency for social insurance registration. The state establishes a national unified personal social security number. Personal social security number is a citizen's identity number.
