After you buy a digital certificate, you should be given a password, and then you will be activated at that time. As long as it can be activated, it means that the information inside is complete, and you can go home and log in to Beijing's online social insurance service platform-company users can log in. Install the driver of digital certificate before logging in, and then you can do related operations.

To social security, the jargon is called "increasing staff." There are two kinds of people to add, one is called new participation and the other is called transfer. The new insurance means that you have never been insured in this co-ordination area (the emphasis here is on this co-ordination area, for example, this person used to be insured in Henan and now comes to Beijing, or he has never been insured. Generally speaking, he has never been in the same co-ordination area, because he can't find a co-ordination area now. Transfer is what you said. Some colleagues were in other units before, and you can do it now.

When transferring, you don't need to go to the social security hall, go to the online platform, log in, enter the business declaration on the left, select ordinary staff to add, then enter the ID number and name of the person to be added, click Query, and his current information will appear on the right. If it is transferred out, you can check all five risks, then enter the base number and click Submit.

If you are a new insured, you should enter the relevant information, then print the personal information form, post photos, copy your ID card, and then go to the social security hall to review him and make a social security card.

The above is my brief introduction. I suggest you go to the social security hall and look at the bulletin board. Generally, there will be relevant training, free and clear.

The above is my answer, I hope it will help you.
