If you meet the requirements for credit card processing, Bank of Ningbo will not refuse to apply for a card for you. There may be some other reasons, you can call customer service to ask. Usually, the reason why you fail to apply for a credit card is that your comprehensive score is not up to standard, which means that you do not meet the requirements of the bank to apply for a credit card, so you will be rejected. The supporting documents required for handling credit cards are:

1. Applicant's identification (required)

A copy of the identity card of a domestic resident; Compatriots from Hong Kong, Macao and Taiwan-Hong Kong and Macao residents' passports to and from the mainland, Taiwan Province compatriots' passports to and from the mainland and copies of residence endorsements or multiple round-trip endorsements; Alien-a copy of the passport and residence permit or employment certificate of the country to which the foreigner belongs;

2. Work certificate (at least one of which must be provided)

Such as: the original official work certificate issued by the work unit, the original work card or business card with comprehensive information, the name of the unit, the name of the applicant and the social security/medical insurance/provident fund certification materials for the last three months.

3. Financial income voucher (optional, which is helpful to increase the quota)

Such as: original or photocopy of payroll records issued by the bank, income certificate issued by the unit, income tax withholding certificate, self-owned real estate license/house purchase contract/bank mortgage repayment schedule, self-owned car driving license, Huaxia Bank deposit certificate and other materials.

If you provide too few application materials, you will also fail to apply for a credit card. I suggest you find out your reasons now. If not, ask the bank directly, or it may be a mistake on the part of the bank.
