Preparing and Addressing Outgoing Domestic Mail
The USPS requires that all outgoing NIH official mail bearing a NIH (G-series) Permit Imprint number, Business Reply Mail (BRM) permit number or a Government postage meter stamp, must have a complete NIH return address and bear the required penalty statement "Official Business Penalty for Private Use, $300".
The return address tells the USPS where the sender wants the mail returned, if it is undeliverable. If a return address is not included, the mail is sent to the dead letter section of the Post Office where it will eventually be destroyed.
A complete return address should be included on all correspondence. The following format for the return address is recommended:
Mailer's Name (Optional)
Mailer's Organization (Institute, Center, Division, Branch, etc.)
Mailer's Street Address (bldg, street name, rm., MSC)
Mailer's City, State, and Nine-digit Zip Code
PENALTY FOR PRIVATE USE, $300
Sample Return Address
Dr. John Doe
National Institutes of Health/NIAAA
22 Success Pl Rm 9030 MSC 0080
Bethesda MD 20892-0080
PENALTY FOR PRIVATE USE, $300
Section VI of this mail guide contains a sample of a properly addressed envelope, a listing of USPS directional and secondary address indicators, a list of state abbreviations and a list of the most commonly used street abbreviations.
It is best to capitalize the address and eliminate all punctuation as this will speed machine processing by the USPS. The USPS list of common address and state abbreviations on pages 29-30 of this guide should be used. Always place the address or post office box on the line above the city and state and always place the ZIP+4 Code on the last line.
