What is the construction credit card number?

When applying for a credit card online, a string of red numbers will be displayed after submitting the application. This is the application number. After the subsequent online application is approved, CCB will send a face-to-face SMS to inform this code. If you ask about the registered letter code of the mailing card, CCB will send the card about 3-5 days after the credit card is approved, and a short message will be sent to you when sending it. This message will inform you of the code of the registered letter. You can call the postal customer service hotline 1 1 185 to check the delivery situation. If you don't keep these two codes, you can call the customer service hotline of CCB Credit Card 400.
