The law requires that the Postal Service respond to requests within 20 working days from the date the Postal Service receives the request. If the request is referred to a records custodian by a FOIA RSC, the referring FOIA RSC will supply the records custodian with the request’s due date. Within 10 business days of receiving a referral of a request from a FOIA RSC, the records custodian must confirm by email that his or her office is processing the request and provide the name of the person(s) within his or her department that are handling the request.
