The Privacy Act allows agencies to disclose information from a system of records if they establish a routine use describing the disclosure (see #3. above). Under the Privacy Act, routine uses are defined as disclosures that are compatible with the purpose for which the information was collected — in other words, disclosures that are appropriate and necessary for the efficient conduct of government business. Routine uses for each system of records are established by publishing them in a Federal Register notice that describes the system. They must also be disclosed in a notice given to an individual when information is collected directly from the individual. The Privacy Act also allows disclosures required by the Freedom of Information Act (FOIA) (see #2 above). USPS regulations implementing the Privacy Act and FOIA are contained in 39 CFR Parts 261-268.
