   First-Class Mail
   Package Services

  1. Mail Piece Preparation
    The sender is usually responsible for all mail piece preparation – packaging, addressing, sorting, etc. We can seal envelopes up to 6½ x 9½ inches if the envelopes are flapped over each other. For more information, please see the Mail Piece Design and Addressing Web pages.

  2. Mailing Preparation
    Please separate your mail by class of service: First-Class/Priority Mail, Parcel Post, Media Mail or Library Mail. Bundle or box up similar types and sizes of mail together: post cards, letters, flats or packages. We can loan you letter trays, flat tubs or package sacks.

  3. Mailing Instructions Form
    Please attach a completed white Domestic Mail form to each bundle, box, etc. filing in:

    • Department name and finance or commercial account number.
    • Sender's name and telephone extension (if we need to contact someone).
    • Check a classification.
    • Check any optional services desired. If you are using any optional services, please complete and attach their forms to the Domestic Mail form or to the proper place on each mail piece.
  4. Mailing Deadlines
    It is our goal that outgoing mail received by 3:30 p.m. is given to the Postal Service the same day. The mailing deadlines for the holidays and breaks are listed on Our Hours page and are published in Off the Beam, our newsletter to faculty and staff.

   Presorted First-Class Mail
   Standard Mail
   Presorted Bound Printed Matter

Mailings of these types have unique mail piece and mailing preparation requirements. Because of this, we highly recommend that you involve us as close to the beginning of your planning for these mailings as possible. For more information about these mailings, contact 674-2865.
