The recommendation code can be filled in or not. If there is one, fill it in. If not, don’t fill it in. The recommendation code must be given to you by China Construction Bank. You cannot fill it in casually. One recommendation code is for one customer. Generally, CCB needs to recognize that you are a very high-quality customer. For example, you have a large amount of deposits, fund management, etc. in CCB. I’ll give you a referral code, which ordinary customers don’t have.

You don’t need a recommendation code to apply for a card. I remember that you only need to fill it in if it is recommended by a bank staff member, and it is filled in by the staff and does not require the applicant to fill in the recommendation code. Some people also receive the recommendation code in personal online banking. You can look at the personal information in online banking. If you don't have it, you don't need to fill it out.

: The basic conditions for applying for a CCB credit card are: be between 18 and 70 years old and have full capacity for civil conduct; have a stable career and income, be able to repay principal and interest on time, and have good credit. This requirement is not high. If you work in a formal unit, your unit pays five social insurances and one housing fund continuously, and your personal credit record is good, it is possible to get a credit card. ?

You can apply online directly on the CCB official website. If you have a CCB online banking shield, you can choose to verify the online banking shield when applying, so you don't need to go to a branch for an interview later. New customers who have not verified the online banking shield must go for an interview. After passing the preliminary review, the bank will send you a text message asking you to go to the nearest CCB branch for an interview.

You only need to provide the original ID card during the interview, no other materials are required. In addition, you can also apply for a credit card through mobile banking and WeChat (China Construction Bank). If you can submit some proof of financial resources and hope to get a higher limit, it is recommended to prepare your ID card and proof of financial resources and go to a nearby CCB branch to apply. Pay attention to the text message after applying. The bank will send you a text message after the review progress and results are available.
