I have researched this. As long as you apply for a CCB credit card online, no matter where you are from, the CCB application number will always start with 999. If you fill out a written application form to apply for a card at the counter of China Construction Bank, the number of the application form will start with the branch number of China Construction Bank. For example, it starts with 310 in Shanghai, and 340 here in Anhui, including in Wuhu. Starting with 340.

The progress of online credit card applications is also very fast. As long as you fill out the application form online and submit it, you can check the application progress immediately. However, the written application form submitted by the branch is a bit slower. It can only be checked after the branch has entered it into the application progress system. Generally, it will not be available until 2 weeks after the application.
