Will the inter-provincial payment period of social security be automatically merged?

No. There may be differences in social security systems between different provinces, including payment standards and calculation methods, so the inter-provincial payment years of social security will not be automatically merged. If the insured person has a basic old-age insurance relationship in two or more places at the same time, when handling the transfer of the basic old-age insurance relationship, the social security agency at the transfer place will negotiate with me to determine to keep one of the basic old-age insurance relationship and personal account, and other relationships will be cleared at the same time, and the amount of personal account storage will be returned to me, and the corresponding individual payment period will not be counted repeatedly.
