Free USPS Shipping Supplies: What You Can Get

USPS offers genuinely free shipping supplies — boxes, envelopes, labels, even packing tape in some cases — delivered to your door at no charge. This is one of the best-kept secrets of ecommerce shipping. For sellers using USPS Priority Mail, free supplies can save hundreds of dollars a year.

What's Free (and Shipped to Your Door)

• Priority Mail boxes (Flat Rate and regular Priority Mail) — Small, Medium, Large, Extra-Large
• Priority Mail envelopes (padded, cardboard, and plain)
• Priority Mail Express boxes (fast service)
• Priority Mail International boxes (free for international Priority Mail)
• USPS-branded shipping labels and customs forms
• Priority Mail stickers and tape (sometimes included)

How to Order

1. Go to usps.com/shop → 'Free shipping supplies'
2. Browse by category (Priority Mail boxes, envelopes, etc.)
3. Select quantity — USPS ships up to 50 boxes at a time for no charge
4. Enter your address
5. Submit — USPS ships the supplies within 7-14 days

What's Not Free

• Ground Advantage packaging (you buy standard boxes yourself)
• Generic corrugated boxes (not specifically for Priority Mail)
• Custom-printed or branded packaging
• Bubble wrap and packing peanuts (buy separately)

Best Free Supplies for E-commerce

• Priority Mail Small Flat Rate Box (8 5/8 × 5 3/8 × 1 5/8) — $10.40 flat rate, fits small items
• Priority Mail Medium Flat Rate Box (11 × 8.5 × 5.5) — $17.90 flat rate, mid-size
• Priority Mail Large Flat Rate Box (12 × 12 × 5.5) — $23.90 flat rate, bulky items
• Priority Mail Flat Rate Envelope — $10.40, padded options available
• Priority Mail Regional Rate Boxes — zone-based pricing, often cheaper than Flat Rate for zones 1-4

Practical Tips

• Order multiple sizes to cover various item types
• Reorder before running low — boxes take 7-14 days to arrive
• Free boxes can ONLY be used for Priority Mail — don't use them for Ground Advantage (carriers will reject or surcharge)
• Brand-imprint your own label on the outside for a polished look
• Recycle old USPS boxes when you receive them — keep 1-2 of each size in inventory

Bottom Line

Free Priority Mail supplies from USPS are real, reliable, and widely underutilized by small sellers. If you ship via Priority Mail at any volume, get in the habit of ordering 20-50 boxes at a time every 2-3 months. Free shipping supplies are one of the few genuinely free-forever perks in ecommerce.
