Take China Merchants Bank as an example. Besides age, the most important condition for applying for a credit card is a stable job and income. The necessary application documents are copies of identity certificate and work certificate. If other financial documents can be provided, it will be more helpful to judge the credit limit.
Credit card applications are comprehensively evaluated by the system, during which there are many factors, such as age, job stability, income, personal credit and so on. It is very likely that the application materials failed to fully show your real situation, which led to the failure of the application. If the application fails, China Merchants Bank will generally send a text message to the applicant on the sixth day, and if the mobile phone number is abnormal, it will send a paper return notice.
If you really don't know the reason why the application was rejected, it is recommended to call customer service to communicate with bank customer service. After supplementing the materials, you can re-provide the information application after the application is rejected for 3 months.
