Legal analysis: To be a guarantor of other people's bank loans, you generally need the original ID card, photocopy, household registration book, monthly income certificate and running bill of the guarantor.

Legal basis: Article 17 of the Regulations on Household Registration in People's Republic of China (PRC) stipulates that if the contents of household registration need to be changed or corrected, the head of household or himself shall report to the household registration authority; If it is verified through examination, the household registration authority shall change or correct it.

When the household registration authority deems it necessary, it may require the applicant to issue a certificate of change or correction.
