Use the student's full name, campus mailbox number, residence hall, and the college mail center address, exactly as the college prints it. A letter sent to a dorm street address alone often stalls, since campus mail is sorted by mailbox number first, and a missing box number can send your letter into a holding pile.
Most colleges run their own mail center, which acts as a post office inside the campus. Outside mail arrives at that center, gets sorted by student mailbox, and is then placed in a box the student checks, or held for pickup with a slip in the box. The street address of the dorm building is often not the delivery address at all: it is just where the building sits. What the mail center needs is the student's name plus the mailbox identifier the college assigned.
Formats vary by school, and the variation is the trap. Some schools use a box number, some use a combination code, and some use the residence hall plus a room number. The only reliable source is the college's own mail services page or the address the student gives you from their student portal. Copy it character for character, including abbreviations like "MSC" or "CPO" that look odd but are part of the routing code.
| Address piece | What goes wrong without it |
|---|---|
| Student's full legal name | Nicknames can fail to match the mailbox roster |
| Campus mailbox or box number | Mail center cannot sort it to a box |
| Residence hall name | Helps staff route mail when the box number is unclear |
| College mail center address | Without it, outside carriers may deliver to the wrong campus building |
| City, state or province, postal code | Standard postal sorting still applies before campus sorting |
Off-campus students are simpler: they have an ordinary street address, and you mail to it like any other home address. The catch is how often students move. A lease that started in September may end in April, and a letter sent to last year's apartment in June will reach a stranger or bounce back. Ask the student to confirm the address close to the time you mail, especially near the end of a term.
Summer addresses deserve the same check. Many students spend summers at a family home, an internship city, or a sublet, and campus mail centers often forward mail only for a limited window after move-out, if at all. A letter mailed to a campus box in July may sit unclaimed until September, or be returned. When in doubt, ask where the student will actually be when the letter should arrive.
Timing matters more than most senders expect. A letter mailed the week before final exams arrives when the student is least able to enjoy it, and a letter mailed during reading week may sit in a box the student never opens until exams end. The sweet spots are the first weeks of term, when homesickness peaks and mail is a genuine lift, and the quiet middle weeks, when a letter gets read properly.
Birthdays are the obvious exception: mail early enough that the letter arrives on or just before the day, not a week after. Campus mail adds a day or two beyond ordinary delivery, since the college mail center is a second sorting step. Build that extra step into your timing, and do not trust a letter mailed on a Friday to reach a campus box before the weekend.
Keep it light, specific, and free of pressure. Students get plenty of mail that asks for something: forms, bills, deadlines. A letter that simply tells them what is happening at home, asks about one concrete thing they are doing, and says you are proud of them stands out precisely because it asks for nothing. Name a detail: the dog, the garden, a sibling's game. Generic encouragement reads as filler, and students can tell.
Resist the urge to fill the letter with advice about grades, money, or health unless the student asked for it. One line of advice lands fine; a page of it reads like a lecture from home, and the letter may be the last one the student opens eagerly. If you have real news, good or bad, put it plainly near the start rather than burying it, since students skim mail the way they skim everything else.
Yes, as long as the student is at a US or Canadian address. Describe the letter and the full campus address to your AI assistant, approve the exact quoted price, and it is printed and mailed in a double-window business envelope, with the recipient's address showing through one window. LetterAgent prints letters only, with no inserts, so if you want to send a gift card or a small item, that travels separately through your own envelope or a parcel service.
One practical note: the double-window envelope shows the addresses printed on the letter itself, so make sure the campus address block on the letter matches the college's format exactly. A mismatch between the letter's address block and the envelope's window can confuse campus mail staff, who sort partly by what they see through the window. Proofread the address block twice before approving the send.
