There are two kinds of credit cards issued by ICBC: the standard version and the popular version, which is why ICBC has become the bank with the largest credit card circulation in China. The credit card limit of the popular version is 0-2000, and those exceeding 2000 belong to ICBC standard cards. Therefore, your card belongs to the popular version after application, and the credit card limit of the popular version is automatically adjusted, and the accumulated consumption reaches 500 within three months from the date of card opening. After adjusting the quota, the cumulative consumption quota in 500 yuan reached 1000 three months later, and it was automatically adjusted to 500 three months later, and then to 2000. However, it will not be adjusted automatically after 2000, because it has reached the upper limit of public credit cards. However, if you want to adjust the credit limit, you can only bring your own income certificate or other documents that can prove your financial source, such as real estate license and driving license, including driving license. The more certificates you provide, the better. If not, you can apply for proof of income, but the amount is not too much. It is the so-called popular version to upgrade the standard version. ...

Generally speaking, the credit card limit adjustment is automatically adjusted by the system. You can adjust it every six months according to your consumption records. It can be temporarily adjusted by manual customer service. The better your credit rating is, the faster the adjustment will be. You can only wait for the bank to automatically adjust it for you.

Finally, if you want to return your card, you should generally call the credit card free service hotline first. Many credit cards require that there is no debt and the deposit balance does not exceed 100 yuan. If your card meets the requirements, you can apply for cancellation through the credit card free service hotline. After success, you will usually go to the counter to sell the card after 45 days, and any counter in the country can do it.
