How to Address a Letter to Fort Jackson Basic Training
Fort Jackson trains more soldiers in Basic Combat Training than any other Army installation, which also means its mailroom sorts an enormous volume of family mail every week. Getting the unit line right is what keeps your letter moving instead of sitting in a pile. The parts of the address that are the same for everyone at Fort Jackson are filled in below; you only need the details specific to your soldier.
The address format
Everything in brackets comes from your recruit. The city, state, and ZIP are the same for everyone training here.
Build the Fort Jackson address
Fill in what your recruit told you and copy the finished address. Free, and nothing you type here is sent anywhere.
Pre-filled with the usual starting rank for this branch. Change it if theirs is different.

What families get wrong at Fort Jackson
The street address is not the same for everyone
Fort Jackson assigns buildings by battalion, so the street line changes depending on where your soldier is training. This is the one field a guide cannot fill in for you. Use the address exactly as it appears in the letter or phone call your soldier sent home, not an address you found for a different battalion.
Mail usually starts after the first week
Soldiers spend their first days in Reception Battalion before moving to their training company, and the address they give you during Reception is often not where they will actually be. If you have not received an address yet, waiting a few days is better than guessing.
Expect the unit line to change mid-cycle
Platoon and company assignments can shift during the training cycle. If mail suddenly stops getting through, ask your soldier to confirm their current unit line rather than assuming the letter was lost.
Would rather not mail it yourself?
Write your message and we will put it on paper, address it to Fort Jackson in the format above, and mail it for you. Pen on paper. Never a printed font. Letters from $5, cards from $9, no account needed.
Send Mail to Fort JacksonCommon questions
What does the battalion number in a Fort Jackson address mean?
A designation like 3-13 IN BN means 3rd Battalion, 13th Infantry Regiment. Write it the way your soldier wrote it to you. The hyphenated form is what the mailroom expects to see.
Can I send a letter to Fort Jackson before I know the platoon?
It is better to wait. Without a complete unit line, mail at an installation this size is likely to be delayed or returned. Most families have a full address within the first week or two.
Should I put a return address on the envelope?
Always. Unit assignments can change during training, and without a return address a misdirected letter is simply gone instead of coming back to you. This is the single most recommended habit in basic training mail guidance, and it is why a return address is required rather than optional on anything we send.
Can I send a package or put something inside the envelope?
Most basic training installations restrict packages, especially early in the cycle, and many prohibit enclosures like food, electronics, or anything bulky. Letters and flat photos are the safest thing to send. Check your installation's current guidance before mailing anything else.
How long does mail take to arrive?
Transit time depends on where you are mailing from, plus a few days on the installation for the mailroom to sort and distribute to the training unit. Mail is not usually handed out daily, so a letter that seems slow is very often just waiting for the next mail call.
What happens if the unit information changes during training?
It happens regularly. If mail stops getting through, ask for a current address rather than assuming anything was lost. A return address means older letters find their way back to you rather than disappearing.
