If unusual conditions, such as excessive street parking, make it impractical or difficult to serve boxes at the curb, customers may install boxes at the edge of the sidewalk closest to their homes. These boxes can then be served from the sidewalk by the carrier. The local post office makes this determination after all other delivery options, including central point delivery, have been explored. General Delivery General delivery is used primarily at post offices without carrier delivery or those serving transients and other customers who do not have a permanent mailing address. The mail can be picked up by the addressee on request at a retail window.
Proper identification is required.
In offices with carrier delivery, customers ineligible for carrier delivery may also receive their mail through general delivery. Contact your local postmaster for more information. Complete Form 3575, Change of Address Order , and deposit it with your local post office. Whenever possible, notify your post office at least 1 month before you move to ensure uninterrupted service. Be sure to notify your correspondents also.
