What do you mean by the first admission time?

The first enrollment time is the date when employees register their personal information with the social security department for the first time.

The date of social security registration is not the date of insurance participation, but the date of work participation refers to the date when the employee first joined the work, which is subject to the employee's entry date. Generally, relevant date records can be found in employee files. The date of enrollment refers to the date when employees apply for social security insurance for the first time, which is generally the date when employees apply for personal information registration in departmental social security for the first time. The earlier the social security participation time, the more benefits you enjoy. General old-age insurance must be paid for at least 15 years, and pension can only be received after retirement.

The information that the new insured should carry is as follows:

1, the form provided by the insured unit, in duplicate, with copies of relevant materials and official seals;

2, a copy of ID card, limited to the city's urban personnel;

3 copies of the first page and personal page of the household registration book. If the four insurances are handled together with medical care, please provide a copy according to the above requirements. If it is impossible to provide copies of the first page and personal page of the household registration book due to special circumstances, it shall be indicated in the supplementary form. The unit has verified the relevant information of the payer category and the newly added personnel. If there is any problem, the unit shall be responsible for it and affix its official seal.

To sum up: the date of social security participation refers to the date when employees apply for social security participation for the first time, which is generally the date when employees apply for personal information registration in departmental social security for the first time.
