I want to apply for a credit card of ICBC. I have a mortgage of 165438+ 10,000 in ICBC, as well as a business friend card of ICBC. Last time I went to the outlet, I said that my service star was not enough, and only 3 stars was the best. 1, ID card; 2. Work certificate or income certificate; 3. Work phone, home phone and my mobile phone; 4. Tax payment certificate or real estate vehicle under his own name; 5. Other bank credit cards, etc. The above information is not necessary. It is important to see the bank's requirements and proof of work or income.
