2. Preparing and Packaging Your Box
Proper packaging protects contents from damage and complies with USPS requirements.
Selecting Packaging Materials
- Box Selection: Use a sturdy, corrugated cardboard box slightly larger than your items. Retail options include USPS Priority Mail Flat-Rate boxes (free) or your own box.
- Cushioning: Wrap fragile items with bubble wrap, packing peanuts, foam inserts, or crumpled paper. Ensure at least two inches of padding on all sides.
- Sealing: Use strong packing tape (preferably 2-inch wide). Seal all seams with the H-pattern method: tape down the center seam and both edge seams on top and bottom.
Weight and Dimension Considerations
- Accurately weigh your package using a postal scale or a reliable home scale. Underestimating weight can result in postage due or surcharges.
- Measure length, width, and height. Dimensional (DIM) weight pricing may apply to large, lightweight packages: DIM weight = (Length × Width × Height) ÷ 166 (inches).
3. Labeling and Documentation
Clear labeling ensures efficient sorting and accurate delivery.
Address Standards
- Write or print the recipient’s address in the center of the largest side. Use all capital letters and avoid punctuation where possible:
JOHN DOE 123 MAIN ST APT 4B ANYTOWN NY 12345-6789 - Include a return address in the top-left corner in case of undeliverable mail.
Customs Forms for International Shipments
- PS Form 2976 (CN22): For items up to $400 in value; attaches directly to the outside of the package.
- PS Form 2976-B (CP72): For items over $400; requires printing via online postage services.
- Provide detailed descriptions, quantities, and values for each item.
4. Purchasing Postage
Three primary methods exist for buying and printing postage.
1. At the Post Office
- Bring your packaged and labeled box to a local USPS counter.
- A postal clerk will weigh, measure, calculate postage, and accept payment.

5. Drop-Off and Pickup Options
Once your package is prepared and labeled, choose how to hand it over to USPS.

7. Common Pitfalls and Expert Tips
Even a simple mistake can delay your shipment or incur extra fees. Keep these tips in mind:
- Avoid Prohibited and Restricted Items: Check USPS’s list of prohibited materials (e.g., hazardous chemicals, certain batteries, firearms without proper paperwork).
- Secure Loose Parts: For items with small parts (toys, electronics), package components together to prevent loss or damage.
- Use Flat-Rate Boxes Wisely: For heavy items under 70 lbs, Flat-Rate Priority Mail boxes offer predictable costs regardless of weight.
- Verify ZIP Codes: An incorrect ZIP code can reroute or return your package. Use USPS’s ZIP Lookup tool online.
- Consider Delivery Speed vs. Cost: If timing is flexible, a slower service can save significantly.
- Consolidate Shipments: When sending multiple boxes to the same destination, batch them to reduce trips to the post office.
- Monitor Weather and Holidays: Peak season and severe weather can impact transit times; plan accordingly.
