Credit card issuers with an interest-free period of 56 days include all credit card products issued by Guangfa Bank, Shanghai Bank, Guangzhou Bank, Bank of Ningbo, Industrial and Commercial Bank of China, Agricultural Bank, Bank of Communications and Bank of East Asia. If you hold a credit card issued by the above-mentioned bank and want to enjoy a 56-day interest-free period, then the time you use the credit card should be the safest after the current bill is generated, that is, the day after the credit card bill is generated. Otherwise, you cannot enjoy the 56-day interest-free period.

In addition, the interest-free period of credit cards in other banks is mostly 50 days, such as China Construction Bank, Bank of China, China Merchants Bank, Minsheng Bank, Ping An Bank and China CITIC Bank.

In addition, you can get an interest-free period of more than 56 when you apply for a grace period for repayment. With the longest interest-free period, the next step is to apply for a grace period for repayment, which is the tolerance period. You can call the credit card customer service hotline to apply. It should be noted that some banks do not need to take the initiative to apply for a grace period for credit card repayment. If the cardholder fails to repay on the last repayment date, he can automatically enjoy the grace period.
