You are correct.
Section 222.82(c) Reasonable belief. (1) Requirement to form a reasonable belief. A user must develop and implement reasonable policies and procedures designed to enable the user to form a reasonable belief that a consumer report relates to the consumer about whom it has requested the report, when the user receives a notice of address discrepancy.
You have to do this regardless of whether or not you form a continuing relationship with the consumer. The section that requires you to provide the correct address information to the consumer reporting agency only applies if you form a continuing relationship and if you regularly report to the consumer reporting agency.
