Ordinarily, it is the responsibility of the records custodian (or designee) to respond to an initial request under the FOIA in accordance with the procedures in 4-4. However, in some cases, a FOIA requester service center responds to a request in accordance with the procedures in 4-4. For the purpose of 4-4, “records custodian” means any Postal Service employee who responds to a request under the FOIA. A FOIA requester service center must promptly forward a misdirected request to the appropriate records custodian for response, and notify the requester of the referral.
