People aged 18 and above can consider applying for a credit card, as this is the minimum application requirement for many card-issuing banks. Of course, applying for a credit card doesn't just depend on your age, there are also a number of specific requirements you need to meet.

First of all, applicants need to be over 18 years old, which is the basic threshold. Secondly, having a stable career and source of income is key. Ideally, the applicant should be an urban or rural resident of the place of permanent residence and have a formal position in the workplace, so that the bank can evaluate your repayment ability.

During the application process, a completed and signed credit card application form is essential. It is also important to prepare corresponding supporting materials, which usually include copies of ID cards, employment certificates issued by your workplace, and income certificates, which can prove your legal identity and financial status.

If you are applying for a local credit card with a non-local household registration or an overseas person, or if you are an active military officer applying in your own name, some banks may require additional supporting documents, such as temporary household registration certificate or a credit card issued by the local public security department or Work certificate issued by the relevant department to ensure the compliance of the application.

Finally, each card-issuing bank may have its own unique application conditions, so during specific operations, be sure to understand it in detail and prepare all relevant materials to increase the success rate of your application. In general, as long as you meet the above requirements, you are fully capable of applying for a credit card at the age of 18, but please make sure you have good credit management skills to maintain a good credit record.
