Mail is the single most reliable way to reach your Soldier during Basic Combat Training — more reliable than phone calls, which are limited and scheduled by their drill sergeants. Here's how to get it right.
Wait for Your Soldier's Actual Address
Your Soldier won't have a mailing address until they're assigned to a specific company after Reception (Zero Week), which usually takes 4–10 days. They'll get that address to you by phone call, letter, or postcard, along with the exact format their unit wants. Don't guess or send mail to a battalion address before you have their specific company and platoon — it likely won't reach them.
Typical Address Format
- Rank Last Name, First Name
- [Platoon Letter] Co, [Battalion & Regiment]
- [Unit street address]
- Fort Jackson, SC 29207
The exact wording varies by battalion. Always use the format your Soldier gives you. See our Fort Jackson battalion directory for unit addresses if you need to double-check one.
How Long Mail Takes
Fort Jackson receives more than 10,000 pieces of mail every day, and each battalion hand-sorts over 1,000 pieces of it daily. That extra sorting step, on top of standard shipping, means mail can take up to 10 business days to reach your Soldier once it arrives on post. Send early, especially around holidays.
What You Can Send
- Letters, cards, and photos (tasteful, no alcohol, tobacco, or inappropriate content)
- Religious reading material
- Unscented hygiene items and sunscreen
- Unflavored lip balm with SPF
- Pens, paper, stamps, and pre-addressed stamped envelopes
- Blister pads (like Moleskin)
- Plain menthol cough drops
- Prepaid Visa gift cards
- Disposable razors
What NOT to Send
Prohibited items are confiscated, so it's worth double-checking before you mail anything. Do not send: electronics (cameras, MP3/CD/DVD players), tobacco or vaping products, food or snacks of any kind, cosmetics, alcohol, hand sanitizer, weapons of any type, over-the-counter medications, civilian books or magazines, aerosols, stuffed animals, jewelry (other than a wedding band), or opened/partially used items. Rules vary somewhat by unit, so only send what your Soldier has specifically requested and confirmed is allowed.
A Few Things Worth Knowing
- Mail is never withheld as punishment — it's a federal crime to withhold a Soldier's mail.
- Drill sergeants don't read mail before your Soldier gets it, but Soldiers must open packages and large envelopes in front of them to check for prohibited items.
- Your Soldier is busy and may not write back often — that's normal. Keep sending mail anyway; it's a real morale boost even without a reply.
- Include a few self-addressed, stamped envelopes in your first package so writing back is easier for your Soldier.
What to Write About
You don't need news — ordinary life is exactly what your Soldier misses. Talk about pets, meals, what's happening at home, encouragement, and how proud you are. Avoid stressful family news if you can hold it until they're home; there's often little your Soldier can do from Fort Jackson, and it can be a hard distraction during training.
