How can the Tangshan endowment insurance certification system app not be certified?

It may be that the system is being upgraded, which makes it impossible to authenticate. You can wait for a while before reapplying for certification. Online certification usually has two ways: face recognition and reading authentication, which may be unrecognizable because the elderly can't speak clearly or face recognition is unclear. If you can't authenticate on your mobile phone, you can log off. As long as users carry valid identity documents and social security cards, they can be authenticated at the nearest social security institutions, street community service points and social security autonomous integrated machines. Under special circumstances, you can also make an appointment with the nearest social security staff for on-site service to help with certification.
