Wuhan social security card and medical insurance card are the same card?

Well, it's the same card, and the account numbers are all your ID numbers.

I didn't check it at the ATM.

However, you can call 12333, which is a unified consultation hotline for medical insurance and social security.

Working days and working hours are answered by workers, which is very professional.

Calling this number is the basic call charge (the number in Wuhan is the local call charge in Wuhan)
