How to Address Interoffice Mail

To ensure that intramural mail is handled as expeditiously as possible, please follow these instructions:

• Use the correct mail codes (also known as the United States Postal Services (USPS) Zip+ Four Number) 
  • If the building does not appear on the mail code list, it does not receive intramural mail 
  • Departments without a mail code must obtain one from Penn Mail Services

• Proper addressing should include the following: 
  • Cross out preceding addressing
  • Name of addressee
  • Department name/Room or Suite number
  • Building name 
• Departments relocating to an existing or new building—requires three weeks notice to Penn Mail Services 
  • Penn Mail Services administers all mail codes which are associated with buildings and cannot move when a department moves
  • Departments must submit a change of address form to Penn Mail Services and the proper mail code will be assigned
