1. Free USPS Shipping Boxes
Many USPS shipping boxes are provided free for use with specific services. These include:

- Priority Mail Express Boxes: For expedited, overnight shipping.
- Regional Rate Boxes: Prices based on distance and box size, great for heavier items shipped locally.
- Global Mailing Boxes: Specifically for international flat-rate services.
You can pick up these boxes at your local post office or order them online for home delivery.
2. Using Your Own Boxes
- You can also use your own packaging for USPS shipments.
- Boxes must be sturdy, undamaged, and appropriately sized for contents.
- For Priority Mail and Priority Mail Express, you may only use free USPS-branded boxes with those services.
3. Specialty Boxes
USPS offers specialty boxes, such as:
- Boxes for books and media (Media Mail)
- Boxes tailored for APO/FPO addresses (military mail)
- Tubes for rolled documents or posters
USPS Shipping Services and How They Affect Prices
USPS shipping prices depend on a few major factors:
- Service selected (speed, tracking, insurance)
- Box type (regular, Flat Rate, Regional Rate)
- Package size and weight
- Destination (domestic or international)
Here are the most common USPS shipping services:
1. Priority Mail
Priority Mail is the go-to service for fast, affordable shipping anywhere in the US—usually 1-3 business days. Prices are determined by weight and zone (distance), unless you use Flat Rate boxes.
Priority Mail Flat Rate
- Medium Flat Rate Box: Great for books, electronics, or clothing.
- Large Flat Rate Box: Suited for even larger, heavier items.
- Flat Rate Envelope: Perfect for documents or small items.
Key Benefit: If it fits, it ships—for one rate! No weighing or calculating distance for domestic shipping.
2. Priority Mail Express
This is USPS’s fastest service, with overnight delivery to most US addresses—ideal for urgent shipments.
- Includes a money-back guarantee, tracking, and up to $100 insurance.
- Uses both Flat Rate envelopes and boxes, or your own packaging.
3. First-Class Mail & First-Class Package Service
- Best for lightweight packages (under 16 ounces).
- Ideal for cards, letters, and small packages.
4. Retail Ground / Parcel Select
- Economical for larger, heavier, or non-urgent packages.
- Longer delivery window.
5. USPS Media Mail
- Special rate for books, CDs, DVDs, and other educational media.
- Slowest but cheapest for qualifying materials.
6. International Shipping
- Services like Priority Mail International and Priority Mail Express International.
- Offers Flat Rate boxes for international destinations, with size and weight restrictions.
How USPS Shipping Prices Are Calculated
USPS pricing can seem complex, but here’s what you need to know:
1. Weight and Size Matter
- For most services, USPS calculates price by actual weight or “dimensional weight” (for large, lightweight boxes).
- The heavier and larger the item, the more it costs—unless you use a Flat Rate box.
2. Distance (Zones)
- USPS divides the US into “zones.”
- The farther your package travels from the origin, the higher the label’s zone number and cost (except for Flat Rate services).
3. Service Speed
- Express and Priority options cost more than slower services like Retail Ground.
4. Extra Services
Add-ons like insurance, signature confirmation, and expedited delivery can affect total price.
