How to check the mobile phone number you have used? It's actually quite simple.

1, just bring your ID card to the business hall of the local operator.

2. You can also check online, log in to your online business hall, go to Personal Information Management → Personal Information → One-Card Multi-Machine Query, and find all the mobile phone numbers that were previously handled with your ID card.

If you don't have the mobile phone number of your ID number before, you won't be able to find it. After all, real-name authentication hasn't started in the previous year.
