What do you mean by multiple social security agencies?

Social security affairs are handled by many different institutions, not by one institution.

Multiple social security agencies mean that your social security affairs are handled by multiple different agencies, not by one agency. This happens when you work or live in different areas, or change social security institutions at different time periods. I have worked in different cities, and each city has its own social security agency, so your social security affairs are handled by these different agencies. Each organization is responsible for managing and processing your social security payment, reimbursement and welfare application within its jurisdiction. When dealing with social security-related affairs, it is necessary to contact and coordinate with these different social security institutions. You need to provide relevant personal information and certificates, and go through the corresponding procedures according to the regulations and procedures of various institutions. If there are more than one social security service number, you can go to the nearest social security service agency in the town or the social security agency in each district, and carry the original ID card to go through the formalities of merging individual social security numbers. You also need to cancel the terminated personal social security card number at the local tax department.
