An SCF is a central mail processing facility with those three digits. The SCF sorts mail to all post offices with those first three digits in their ZIP Codes. The mail is sorted according to the final two digits of the ZIP Code and sent to the corresponding post offices in the early morning. Sectional centers do not deliver mail and are not open to the public though the building may include a post office open to the public, and most of their employees work night shift. Mail picked up at post offices is sent to their own SCF in the afternoon, where the mail is sorted overnight.
