When applying for a credit card, the email address you fill in is very important. Make sure it is commonly used and valid. The email format should follow the standard of "username@email domain name.COM". For example, if your email is a qq email, just replace your qq number with your username, such as "1234" becomes "1234@qq.com".

If you use the email address of Sohu, Sina and other websites, be sure to register a dedicated email address on the website first, because these emails will be used during the credit card application process. Make sure your registered email address is activated and available.

Credit card applications usually include individuals with full civil capacity (18 years and above) and stable financial resources. Sometimes legal persons can also apply. Unit applicants need to be enterprises or self-employed individuals with independent legal personality and can apply for the main card and supplementary card. Individual applicants need to have a fixed job and source of income, and may be required to provide guarantees, such as personal, unit or financial guarantees.

Usually, applicants need to fill in a detailed credit card application form, including personal information, financial status, guarantor information, etc., and attach copies of relevant documents and certificates. Applicants need to sign a contract, agree to the card issuer's investigation of personal information and ensure the authenticity of the information, and accept the card issuer's privacy policy.
