To send a care package, fill a sturdy, right-sized box with shelf-stable items, pack heavy things on the bottom and seal anything that could leak, then address it clearly with a return address. Buy a USPS Ground Advantage or Priority Mail label online and drop the box at a Post Office or schedule a free USPS pickup. For a small, heavy box, a Priority Mail Flat Rate box often costs least, because one price covers any weight up to 70 pounds to any U.S. address.
The same steps work for a college student, a service member overseas, a friend recovering from surgery or a family member across the country. What changes is the address format, the paperwork and which items are allowed. This guide covers each case.
How Do You Send a Care Package, Step by Step?
- Pick the contents. Choose shelf-stable food, toiletries, practical supplies and one or two personal touches. Check the restrictions below before you add liquids, aerosols or anything alcohol-based.
- Choose the box. Use a corrugated box with a little room for padding. A free USPS Flat Rate box is a good option if your items are dense.
- Pack it. Heavy items go on the bottom, leak-prone items in sealed bags, and filler in every gap so nothing moves.
- Seal and label it. Tape every seam with 2-inch packing tape, cover any old labels or barcodes, and put a copy of the address inside the box.
- Weigh and measure it. The carrier prices by weight, size and distance, so an accurate weight and size gets you the right price the first time.
- Buy the label and ship it. Compare services, print the label (or use a printer-free code), then drop the box off or request a free USPS pickup.

What Should You Put in a Care Package?
Most non-hazardous items are mailable, so the limits are mostly common sense: will it survive several days in a truck, and is it allowed where it’s going? These categories travel well:
- Shelf-stable snacks: granola bars, nuts, crackers, jerky, dried fruit, individually wrapped treats.
- Toiletries: travel-size shampoo, lotion, lip balm, wet wipes and toothpaste, each bagged in case it leaks.
- Comfort items: warm socks, a small blanket, tea or cocoa packets.
- Entertainment: paperbacks, puzzle books, playing cards, a handwritten letter and printed photos.
- Practical supplies: phone chargers, stationery, laundry pods, batteries left in their original packaging.
Leave out or double-check a few things. USPS doesn’t accept beer, wine or liquor except in limited circumstances. It treats hand sanitizer and alcohol-based perfume as hazardous materials that can only travel by ground domestically, and it prohibits them in international and military mail. Liquids in general are fine if they’re non-hazardous and sealed so they can’t leak.
Homemade baked goods ship well in airtight tins. For anything that needs to stay cold, see our guide to shipping perishables and food.
Which Shipping Service Is Best for a Care Package?
For most care packages the choice is between USPS Ground Advantage, which is cheaper and slower, and Priority Mail, which is faster and offers Flat Rate boxes. UPS Ground makes sense for heavy or bulky boxes. The table compares them on delivery time and weight limits. Prices vary with weight and distance, so compare them for your actual box.
| Service | Delivery commitment | Max weight | Included coverage | Best for |
|---|---|---|---|---|
| USPS Ground Advantage | 2–5 days | 70 lbs | Up to $100 | Light, non-urgent boxes |
| USPS Priority Mail | 2–3 days | 70 lbs | Up to $100 | Faster delivery, Flat Rate boxes for dense contents |
| USPS Priority Mail Express | 1–3 days | 70 lbs | Up to $100 | Time-sensitive or perishable contents |
| UPS Ground | 1–5 business days | 150 lbs | Up to $100 declared value | Heavy or bulky boxes |

How Do You Pack a Care Package So Nothing Breaks or Leaks?
USPS asks for packaging that doesn’t bulge and is strong enough to protect the contents, with room for cushioning around fragile items. Reused boxes are fine if they’re still sturdy, but cover or black out every old label, logo and barcode first.
- Layer by weight. Cans, jars and books go on the bottom, lighter snacks in the middle, and soft items such as socks or a blanket on top as padding.
- Double-bag liquids. Put each bottle in its own zip bag, and tape flip-top caps shut.
- Wrap fragile items individually. Use bubble wrap or paper, and keep at least a couple of inches of cushioning between each item and the box wall.
- Fill every gap. If something rattles when you shake the box, add filler. Crumpled paper and shredded paper both work.
- Skip string and twine. USPS warns they can get caught in sorting equipment. Use tape.
Don’t use a box much bigger than the contents. USPS bills Priority Mail and Ground Advantage packages over one cubic foot by size when that’s higher than the actual weight, and UPS applies dimensional weight too. A snug box is both safer and cheaper. Our guide to USPS Flat Rate boxes shows what fits in each size.
How Do You Send a Care Package to Military Personnel?
Packages to APO, FPO and DPO addresses go through USPS to a military mail facility. Follow the USPS addressing rules exactly:
- Include the recipient’s full name, rank and unit, plus the APO/FPO/DPO designation and its 9-digit ZIP Code.
- Leave the city and country names out of the address.
- Address the box to a specific person. USPS no longer accepts mail addressed to “Any Service Member.”
- Put a second copy of the address inside the box, and always include a return address.
Most military packages need a customs form, and Click-N-Ship tells you which form you need. Describe contents specifically (for example “3 bags of beef jerky,” not “food”). USPS offers free Priority Mail APO/FPO Large Flat Rate boxes, free military shipping kits and country-by-country guidance on what you can send. DPO packages can’t exceed 27 inches long, 14 inches wide or 14 inches high. Private carriers handle military addresses differently, and our guide to whether UPS ships to APO addresses explains why USPS is usually the only option.
Can You Send Perishable Food in a Care Package?
Yes, but at your own risk. USPS accepts perishable items only when they’re packed to arrive before they spoil, and the Postal Service doesn’t guarantee they will. Baked goods, hard candy and vacuum-sealed jerky travel well. Fresh dairy, meat and anything that must stay cold need insulation, cold packs and a fast service such as Priority Mail Express.
Ship perishables early in the week so they don’t sit in a facility over a weekend, and warn the recipient when the box is coming. Our frozen and perishable food shipping guide covers insulated packaging, gel packs and dry ice.
How Do You Send an International Care Package?
A care package going abroad needs a customs declaration listing every item, its quantity and its value, and USPS requires more detailed descriptions than it used to. Create the form online when you buy the label. The recipient may owe import duty or tax, and the destination country’s rules decide what’s allowed. Many countries restrict meat, fresh produce and some snacks, so check before you pack any food.
USPS Priority Mail International covers most countries. UPS Worldwide services are faster and have more detailed tracking for higher-value boxes. Either way, plan for longer transit than a domestic shipment and send early for birthdays and holidays.
What Care Package Mistakes Should You Avoid?
- Using an oversized box. Empty space means crushed contents and, past one cubic foot, a dimensional-weight price.
- Packing meltables in summer. Chocolate and gummies can soften in a hot truck. Swap in hard candy or crackers in warm months.
- Incomplete addresses. Military mail needs rank, unit and the 9-digit ZIP, and college mailrooms need the student’s mailbox number.
- Paying retail by default. Buying a label online is usually cheaper than paying at the counter, and comparing services takes a minute.
- Not insuring valuables. USPS Ground Advantage and Priority Mail include up to $100 of coverage. ParcelPath offers Shipsurance for higher-value items.

Frequently Asked Questions
What is the cheapest way to send a care package?
For a light box, USPS Ground Advantage is usually cheapest, and USPS lists it at 2 to 5 days. For a small but heavy box, a Priority Mail Flat Rate box often wins, because one price covers any weight up to 70 pounds. Buying the label online and using a right-sized box keeps the price down.
How do you address a care package to a deployed service member?
Write the service member’s full name, rank and unit, then the APO, FPO or DPO designation and the 9-digit ZIP Code. Leave out city and country names. USPS no longer accepts mail addressed to “Any Service Member,” so every package must name a specific person, and it needs a return address.
Can you mail liquids in a care package?
Yes. Non-hazardous liquids such as shampoo, lotion or sauces can be mailed if they’re sealed and packed so they can’t leak; double-bagging each bottle is the safest approach. Flammable items are different: USPS limits hand sanitizer and alcohol-based perfume to domestic ground transport and prohibits them in international and military mail.
How long does it take to send a care package?
Within the U.S., USPS lists Ground Advantage at 2 to 5 days, Priority Mail at 2 to 3 days and Priority Mail Express at 1 to 3 days. Packages to APO/FPO/DPO addresses and international destinations take longer, so send them well ahead of birthdays and holidays.
Is a care package insured?
USPS Ground Advantage, Priority Mail and Priority Mail Express include up to $100 of insurance, and you can buy more coverage, up to $5,000. UPS includes up to $100 of declared value. If you ship through ParcelPath, you can add Shipsurance coverage for higher-value contents.
