The guarantee center began trial operation in February 2000165438, and officially opened one year later. At present, the business that the guarantee center has carried out includes: providing joint and several guarantee responsibilities for borrowers who apply for commercial housing, affordable housing, housing reform housing, housing, fund-raising housing and second-hand housing loans (provident fund loans, commercial discount loans, commercial loans and portfolio loans) in Beijing. During the guarantee period, the guarantee center shall be jointly and severally liable for the borrower's debt repayment. During the loan period, if the borrower fails to repay the loan on time due to unexpected events, he may apply for loan relief.

In order to further promote the development of guarantee centers and credit information centers, it has been decided by relevant departments that from April 2005, guarantee centers and credit information centers will be co-located according to the principle of complementary advantages and resource sharing. After the joint office, the original responsibilities and business scope of the credit center will remain unchanged. Through the pre-lending credit evaluation of provident fund borrowers, the credit center effectively prevented and reduced the pre-lending financial risks, making the risk control of the guarantee center more standardized and scientific.
