According to the regulations of UnionPay, to apply for a credit card master card, three basic conditions must be met: age between 18 and 65 years old, stable repayment ability and good credit standing. You haven't reached the age requirement, so you can't apply for a credit card master card. If you need to apply for a supplementary credit card, you can ask your parents or immediate family members to apply for it on your behalf, as long as 16 is one year old. The supporting documents required for handling credit cards are:

1. identification: generally, it is an identity card, and the applicant needs to have full capacity for civil conduct;

2. Work certificate: it can be the original work certificate issued by the employer (please indicate the specific company name, department, position and income, and affix the official seal or personnel seal of the company), or it can be a copy of the work permit verified and marked by the sponsor;

3. Proof of financial resources: it can be a payroll record issued by a bank, an income tax withholding certificate, or a market value certificate of a house, a car, a deposit or an investment (such as a copy of the real estate license/car driving license/bank time deposit certificate) and other materials that can prove your economic level.

4. Other documents for reference include: personal account list of social insurance in the last 6 months, water, electricity and gas bills, credit card bills of other banks, etc.

You can also learn about credit card knowledge first, and then apply for a credit card when the above conditions are met. I hope you will consider it carefully!
