1. Dial the bank’s customer service number and ask a customer service representative to help you check the card number. If you transfer it manually, she will verify whether your personal information is the same as the information when applying for the card, which is usually your ID number and name.

2. If you bring your ID card, you can also go directly to the business hall of the bank card bank and go to the counter to handle the inquiry business.

Extended information

In April 2016, the People's Bank of China issued the "Notice of the People's Bank of China on Matters Concerning the Credit Card Business", which came into effect on January 1, 2017.

The "Notice" requires the implementation of upper and lower limit management on credit card overdraft interest rates. The upper limit of overdraft interest rates is 5/10,000 daily interest rates, and the lower limit of overdraft interest rates is 0.7 times the daily interest rate of 5/10,000ths.

Mainly based on the following considerations: First, the implementation of step-by-step and gradual reforms will help card issuers further accumulate pricing data and experience during the transition period, and guide them to improve the credit card interest rate pricing mechanism.

Second, the credit card risk control and pricing capabilities of each card issuer are uneven. The upper and lower interest rate guidance will help prevent individual card issuers from blindly cutting prices and engaging in price wars, resulting in unfair competition and high-risk customers. Excessive borrowing will increase credit risks and cause partial chaos in the market.

Third, while the information disclosure mechanism needs to be strengthened, setting an upper limit on overdraft interest rates will help prevent individual card issuers from unreasonably charging excessive interest and protect the legitimate rights and interests of cardholders.
