For New Students

Welcome all first-year and transfer students! The Campus Mail Services operation is located in the Joe Rosenfield '25 Center. Mail Services is located on the first floor. This memo addresses the following topics: how to determine your mailbox number, how to access your mailbox combination code, and what mailing address to share with others while you are a student at Grinnell College.

Mailbox Numbers

Grinnell College enrolled students are each assigned a mailbox in the campus mailroom. The mailbox holds incoming mail and inter-campus communications. Letters, magazines and small packages will be placed in your mailbox and available to you at your convenience. Large parcels will be stored in the mailroom and available at the service window during regular business hours. The lobby of the new mailroom was designed so that you could access your campus mailbox at your convenience throughout the day and evening, seven days a week.

The mailbox number assigned to you is available on the Online Campus Directory located at: The Online Campus Directory displays campus contact information for all students, faculty and staff at Grinnell College and is updated regularly.

Mailbox Combinations

Student mailboxes are accessed via combination codes. You can now access your mailbox combination code by logging into PioneerWeb from any networked computer on campus or from an off-campus computer with Internet access. PioneerWeb is the campus intranet and course management system and requires a log in username and password. By storing this information in PioneerWeb, your code is secure and available to you at any time of the day or night. Of course, mailroom staff are available to assist you with locating or opening your campus mailbox when you arrive later this month. PioneerWeb is located at:

Mailing Guidelines

Processing Your Mail Quickly and Efficiently

When mail is addressed, bundled and documented accurately, it goes through the mail system more quickly. Some simple guidelines and tips to help you get your mail processed quickly and efficiently are listed below.

  • Package Labels can be filled out and printed with this form.
  • Postcards, letters, large envelopes (flats) and small packages can be sent using First-Class Mail. First-Class Mail prices are based on both the shape and weight of the item being mailed. For items weighing more than 13 ounces, use Priority Mail. Visit for more information about First-Class Mail.
  • If a letter is rigid, contains keys, coins, pens or other rigid contents, additional postage will apply (in addition to a standard First-Class Mail stamp).
  • Sort and/or Separate -Separate International mailings and Inter-Campus mailings from other types of mail.
  • Sealed Envelopes - The mail machine in Mail Services can seal #10 envelopes for you. Nest the envelopes so that the flaps are together; they may face upward or downward - just be sure the flaps nest together.
  • Presealed Envelopes - Envelopes with presealed or peel-off seal flaps need to be sealed by the department before reaching the mailroom.
  • Using Department Accounts - When using a department account to fund a mailing, please complete and enclose a Meter Mail Request form. Meter Mail Request forms are available from Mail Services at ext. 3421.
  • International Mail - Envelopes with a "girth" and packages sent to international addresses must be accompanied by a Customs Slip. Packages that weigh less than 4 lbs. require a green Customs Slip; packages weighing 4 lbs. or more require a white Customs Slip. Mail Services can send a Custom Slip to you, by request.
  • Large Mailings - Please call Mail Services a few days before sending a large mailing (1000 pieces or more) to the mailroom. This gives the staff time to schedule additional student employees in the operation. If the items are being handled by Copy Connection and delivered directly to Mail Services, please call Mail Services at ext. 3421 to let them know that a mailing will arrive in the next day/week from Copy Connection.
  • End-of-day Delivery to Grinnell Post Office - The campus courier picks up items in Mail Services for delivery to the Grinnell Post Office around 3:00 p.m. most weekdays. Exceptions include holidays, closings, etc. It is important that letters and packages requiring meter postage be in the mailroom no later than 2:00 p.m. for processing and loading.
Mailing Perishables to Students

The U.S. Postal Service enforces general rules for sending perishables through the mail. These include:

  • Mailable perishable matter may be sent through the mail only if it can reach its destination in good condition in the normal transit time between the mailing and address points.
  • Mailable perishable foods that do not rapidly decay or generate obnoxious odors in the mail may be sent at the mailer's risk.
  • Any container used to mail perishable matter must be constructed to protect and securely contain the contents.

Campus Mail Services strongly discourages sending perishables (i.e., food) to students by any carrier (UPS, U.S. Postal Service, FedEx, etc). The college is not responsible for perishable items sent to students.

Students are notified when packages arrive for them in Mail Services, but they may delay pick up for days or even weeks.

If it is absolutely necessary to mail a perishable item, please notify the student that the item will be delivered to their campus mailbox address. Most packages do not fit inside student mailboxes, so it is necessary that the student pick up the package at the Mail Services Window during business hours. Packages arriving on a Friday may not be accessible until business hours the following Monday or later if a national holiday falls on that day or during that period.

Forwarding Mail

Magazines and newspapers will be forwarded for up to 60 days provided they are classified as Periodical Class Mail. Parcel Post may be forwarded, by request, to a new address; Postage Due fees will apply (individuals leaving the College may request the forwarding of Postal Post mail by sending a written authorization to the Mail Services manager). Magazines and newspapers falling outside the regulated dates and/or classifications and Third-Class Mail will be recycled or discarded. In compliance with United States Postal Service regulations, Grinnell College Mail Services will forward First-Class Mail and Priority Mail for up to one year after departure for students, faculty and staff on extended leaves or no longer enrolled or employed at the College, including recent graduates. Students, staff and faculty permanently leaving the College are asked to provide a forwarding address to Mail Services (Tel: 269-3421) or to the Office of Development and Alumni Relations (Tel: 269-1846).
