When applying for a credit card (debit card), the user does not have a company phone number, and can directly fill in 000-00000 or fill in other fixed phone numbers. Please note that this fixed telephone number must be dialed and answered by someone. For banks, the company telephone is mainly used to inquire whether users have stable jobs. Without this phone, the user's income is unstable, which may affect the approval result of credit card (debit card).

In addition, users must seriously answer the bank's questions when filling in other fixed-line telephones and encountering bank audits.
