Yes, if a foreigner’s passport number changes—for example, due to passport renewal or replacement—they must report this change to the local Social Security Administration to keep their records up to date.

In Hainan, the Social Security Administration offices handle these updates to ensure that social insurance and related benefits remain valid and properly linked to the individual.
