Departments sending official University mail are responsible for proper preparation of all letters, flats (large flat envelopes), and parcels to addresses off campus. Our mailing machine will seal top flap envelopes if the flaps are open.

Each department must separate mail by KFS account then band into four categories:
1. Interdepartmental Mail.
2. Outgoing U.S. Mail
a. Letters
b. Flats
3. International Mail (Canada, Mexico separate)
4. Special Handling/Services

Addressing
Mail is processed for all University Departments and registered organizations with assigned KFS account numbers which must appear on all outgoing mail for charge back purposes.

When addressing envelopes, please remember that the upper right hand corner of the envelope or parcel is reserved for postage only. Please do not place any classification or address information in this corner. Each piece of outgoing mail, letter, flats and parcels, must carry the following information:

Domestic Mail:
* UCONN ONLY-COMPLETE RETURN ADDRESS
Place KFS account number above return address.

• DESTINATION ADDRESS
  • Name of Recipient
  • Information/Attention Line
  • Street Address or Delivery Line
  • City, State, and Zip +4
• RETURN ADDRESS

Foreign Mail:
* RETURN ADDRESS (Same as above)

• DESTINATION ADDRESS

Various restrictions apply and customs forms may be required. Please call UMS for assistance at 486-2024.

You will receive the best service possible on all categories of mail if you:

• Capitalize everything in the address
• Use common abbreviations
• Eliminate all punctuation
• Use 2 letter STATE abbreviations
• Use Zip + 4 Codes

Make sure the place where you want the mail delivered appears on the line
immediately above the City, State and Zip Code line; i.e., 123 W MAIN STREET,
SUITE 400 or PO BOX 125, BUT NOT BOTH ON THE SAME LINE.

Labels for use on parcels, packages or large envelopes must be addressed
according to RECOMMENDED FORMAT. Improperly prepared labels will be returned to
you for correction and/or completion.

Enclosures

Correspondence:
Mail of any kind for transport by the U.S. Postal Service should be enclosed in an appropriate envelope or parcel and sealed.

Non-mailables:
The following are samples of non-mailables in envelopes:

paper clips glass chips key chains pens/pencils	metal pieces pins coins
and items less than 3 1/2″ x 5″

These will not only jam or damage the mailing machines, but can also cause serious injury to Mail Service employees.
