How many times a year is social security certified, and in which months?

Social security certification is conducted once a year, from May to June 30th.

Social security certification is conducted once a year, generally from May 1 day to June 30 (except legal holidays). This is to ensure the identity and qualification of the insured in order to receive the basic pension on a monthly basis. If the insured retires to receive a pension, he needs to go to the local social security bureau to prove his survival every year and prove that he is still alive and eligible to continue to receive a pension. Therefore, social security certification is conducted once a year, usually from May/KLOC-0 to June 30th every year.
