Foshan has no annual social security review.

In this case, you can continue to buy social security in Guangzhou, and you need to go through the following procedures:

1: Print the payment voucher at Foshan Social Security Center with your ID card and social security card.

2. Submit the payment voucher to the social security center in Guangzhou, and apply for the transfer of social security payment relationship.

3. In fact, Guangdong has long implemented the province-wide pooling of old-age insurance, and the insured with Guangdong household registration can re-pay the insurance premium in any city in the province without handling the social security transfer. Your social security account in Foshan is still there, and so are your previous payment records. Social security contributions are calculated cumulatively, with gaps in the middle. You can choose to supplement or not to supplement the insurance (unless the local policy specifically stipulates that it must be supplemented or not).
