The social security number of a unit, also known as the social insurance registration number, is a unique identification number given to a unit participating in social insurance when it registers with the social insurance institution in its place of registration. This number is mainly used for the management and collection of social insurance, to ensure that the information of each unit is accurate.
The number of digits of the employer's social security number may vary in different regions and periods. Generally speaking, the number of digits of the unit's social security number may be 8 or 10 digits, depending on the specific regulations and practices of the local social insurance authority.
1.8-digit Social Security Number:In some areas, the social security number of the unit is an 8-digit number. This numbering method is relatively concise, easy to remember and operate. An 8-digit social security number usually consists of the following parts:
The first two digits indicate the province or municipality directly under the central government**, such as 11 in Beijing, 31 in Shanghai, etc.
The middle two digits indicate the urban area or district**, which is specific to the city or district level.
The last four digits are the local sequence number of the unit, which is used to distinguish between different units.
2.10-digit Social Security Number:In other regions, your employer's social security number may be a 10-digit number. This numbering method is more detailed and includes the following sections:
The first three digits represent provinces or municipalities directly under the central government**, such as 110 for Beijing, 310 for Shanghai, etc.
The middle three digits represent the urban area or district**, which is specific to the city or district level.
The last four digits are the local sequence number of the unit, which is used to distinguish between different units.
In practice, how to obtain and confirm the number of digits of the unit's social security number:
1.Newly established units:When registering for social insurance, the social insurance institution will assign a social security number to the new employer and provide the employer with relevant supporting materials. At this time, the unit can determine the number of digits of the social security number according to the number on the supporting materials.
2.Existing units:If the employer has already participated in social insurance, you can confirm the digits of the social security number in the following ways:
Look at your employer's social insurance registration certificate, which usually has the social security number on it.
Contact your local social insurance agency to find out more about your employer's social security number.
Find out from the department responsible for social insurance within the unit or a colleague.
It should be noted that the specific digits and composition of the unit's social security number may vary from region to region, and you can consult the local social insurance institution for specific regulations.
The number of digits of your employer's social security number may be 8 or 10 digits, depending on local social security regulations. When handling relevant business, it is recommended to understand the local regulations in advance to ensure the accuracy of the information.
