1. Materials must be prepared in advance, including: business license, organization code certificate, tax registration certificate, bank account opening permit, and legal representative ID card.

2. Register the company's social insurance online in official website, the municipal social insurance fund management center, and print the pre-registration documents generated by social security official website. Some districts need an appointment number to go to the social security center after online registration.

3. Prepare three originals and photocopies of enterprise business license, three originals and photocopies of organization code certificate, three originals and photocopies of tax registration certificate, three originals and photocopies of bank account opening license, three photocopies of legal representative's ID card, company official seal and legal person seal.

In addition, in some areas, in order to allow enterprises to pay social security fees by bank transfer instead of cash, enterprises will be required to go to the bank to apply for a bank social security fee withholding agreement/letter of intent before opening a social security account, and the original and copy of this document must be prepared together when opening an account.

4. Take the printed pre-registration documents and the materials mentioned in the third point and go to the designated social security center (usually the social security center in the area where the company's registered address is located) for social security registration. After the social security registration is completed, the social security center will issue the social security registration certificate. And purchase and activate the enterprise social security digital certificate as required.

Some banks require corporate customers to obtain the social security registration certificate before going to the bank to handle the formal bank transfer agreement. Therefore, customers (general service providers don't involve the customer's bank, otherwise they will charge more for the service) need to go to the bank to sign the agreement with the social security registration certificate, the form returned by the social security center, the official seal and the legal person seal.
