Why can't Leshan handheld social security be found?

There is no national network for social security, so you need to refer to the inquiry system of the provinces and cities where your insured institution is located, and use your ID number and password for inquiry. At present, there is no software that can directly query the insurance information of all provinces.

So I suggest you go directly to the local social security agency or call 12333 during office hours.
