How to Find Your Missionary's MTC Mailing Address

Before you can send a single note or treat, you need your missionary's complete MTC mailing address. It sounds simple, but it trips up more first-time senders than anything else — usually because of one missing detail.

Where the address comes from

A few days before your missionary enters the Provo MTC, they receive an email with their full MTC mailing address, including their assigned mailbox number. That email is the official source and has everything you need. If they don't forward it, the simplest path is to ask them directly — once on site, they can read you the address straight from their materials.

Why the mailbox number is non-negotiable

Here's the detail that matters most: every missionary is assigned a mailbox number, and your package or letter needs it. The MTC handles a huge volume of mail, and the mailbox number is how the mailroom routes your delivery to the right person. Leave it off and your package can be delayed, misrouted, or returned. Double-check it before every send.

How to format the address

Follow the address email exactly. In general, an MTC address includes:

• Your missionary's full name and title (Elder or Sister), spelled as the Church has it on file

• Their mailbox or unit number, kept on the name line so it stays attached to them

• The MTC street address in Provo, Utah, and the city, state, and ZIP

Copy it line for line, including any unit codes. Don't paraphrase, shorten, or add nicknames that might confuse sorting.

What to do if you don't have it yet

If your missionary just got their call or the email hasn't arrived, don't panic. Wait for the pre-entry email (it typically lands a few days before they report), or ask your missionary once they're on site. In the meantime, write your notes and gather your shelf-stable treats so you can send the moment the address arrives. A complete address is worth the short wait — don't send to a partial address and hope.

Before any send goes out, confirm your missionary is still at the MTC. English-speaking missionaries are usually there about three weeks, while language missionaries stay longer, so make sure your package will arrive before they leave.

Once you've got the address

With a complete address in hand, you can mail a package via USPS or UPS, use a same-day service like Rushly to deliver the same business day, or send a free letter through Rushly's letter option. Save the address somewhere safe — store it in your phone and share it with the wider family so siblings and grandparents can write too.

The most common slip-ups to proofread against: leaving off the mailbox number, using a nickname, mistyping a digit, or sending to a stale address from a previous missionary. A quick check against the official email catches nearly all of them. And remember — a handwritten note is the single most-loved thing missionaries receive, so even a quick letter to that brand-new address means the world.
