If you want to apply for a higher credit card, in addition to the basic identity certificate, work certificate and income certificate, you must also provide weighty asset certificates, such as house ownership certificate, mortgage purchase certificate, car ownership certificate, bank deposit certificate or securities certificate. Secondly, the applicant's work unit, personal ability and application experience are also helpful to apply for a high credit card. Banks need to refer to many factors to determine the credit line when evaluating the applicant's personal comprehensive situation. Here are some suggestions to improve your overall score:

1. Whether there is a local fixed telephone (having a local fixed telephone indicates that the residence is stable, which will increase the bank's credit evaluation score for the applicant);

2. Whether or not to get married (the score of married is higher than that of unmarried);

3. Whether it is a local account (the score of local account is higher than that of foreign account);

4. Whether there is a house (having a house is higher than not having a house, and living by yourself is higher than living with parents);

5. Education (the higher the education, the higher the score);

6. The nature of the work unit (the more stable the work unit, the higher the popularity and the higher the score. For example, institutions, large state-owned enterprises, and Fortune 500 enterprises all scored relatively high, while unknown private enterprises and foreign enterprises scored relatively low);

7. Job Description (The higher the position, the higher the score. For example, civil servants and company managers score higher than ordinary employees).
