Detailed Aspects to Consider
While the USPS Flat Rate Small Box is convenient, it is important to understand key aspects for optimal shipping experiences:
Sizing and Restrictions
- Physical Limits: Your contents must fully fit inside the box. If the box cannot be closed flat, it’s not eligible.
- Prohibited Items: Certain items, such as hazardous materials or perishables, are not allowed.
- International Shipping: While flat rate boxes can be used for international shipping, rates differ.
Best Uses
The Flat Rate Small Box is ideal for:

- Books, CDs, or DVDs
- Small clothing items
- Supplements or cosmetics (check restrictions)
When Flat Rate Is Cost-Effective
- Heavy, Small Items: The heavier the item (up to 70 lbs) and the farther it’s going, the more you save. For lightweight, nearby shipments, check if regular Priority Mail is cheaper.
- Long-Distance Shipping: USPS Flat Rate shines for cross-country or Alaska and Hawaii destinations.
Shipping Cost and Money-Saving Tips
Keeping your shipping affordable is a major advantage of the Flat Rate Small Box, but a little knowledge goes a long way:
1. 2024 Flat Rate Pricing

- No surcharges for distance or zones. Alaska, Hawaii, and military addresses cost the same as mainland shipments.
2. Rate Comparison
- Always compare Flat Rate pricing to regular Priority Mail, especially for lightweight shipments. Use USPS’s online postage calculator.
- For very light packages traveling nearby, standard Priority Mail may be less expensive.
3. Free Packing Materials
- Get your Flat Rate Small Boxes for free from the Post Office or order online (limit quantities per household).
4. Save on Postage with Online Tools
- Buying and printing shipping labels online sometimes provides small discounts versus in-person purchase.
5. Combine with Other USPS Services
