What address should I use to mail applications, payments, or other correspondence that will be delivered by the United States Postal Service or by other delivery services?

The USPTO mailing addresses and mail stop designations are provided in each issue of the Official Gazette Notices, under Special Mailstops for Patent Mail . Special mail stops designations should be used for certain correspondence to allow forwarding of particular types of mail to the appropriate areas as quickly as possible.

Other USPTO mailing addresses can be found at Information Contacts Phone Directory > Other Addresses.
