For enquiries, it is only possible at the social security office of the insured place.

For the query, you don't have to worry. In addition to logging in to the local social security network to query (sometimes the function is not perfect and stable), you can also query in the following ways:

(a) the local social security bureau

(2) Call the social security service number 12333.

Remember: the inquiry requires my ID card or social security number.

I suggest you apply to the local social security bureau for inquiry, and you can get satisfactory results.
