The main reasons are incorrect or incomplete addressing, choosing the wrong mail class for your delivery timeline, not properly packaging fragile items, allowing inadequate transit time, and lack of tracking to monitor progress.
Look at each service's typical delivery timeframe and prices to pick what fits your timeline and budget. Priority Mail Express is fastest at 1-2 days. Priority Mail takes 1-3 days. First Class is 1-3 days for lighter packages while Media Mail is 2-8 days.
Always include full street address, recipient name, and phone number in case clarification on delivery location is needed. Avoid abbreviations or "care of" addresses that could confuse automated sorting systems.
Yes, tracking provides visibility into your package's route and estimated delivery date. It also gives recourse if a package does get lost or delayed beyond expectations.
Packages can be delivered on Sundays for an additional fee. USPS does not deliver mail on federal holidays.
Look at USPS estimated transit times and add 1-2 extra buffer days for first class packages. Allow more time for international delivery or locations prone to weather events that could delay regional sorting and delivery.
Use new, undamaged boxes designed for shipping. Sturdy cardboard with reinforced corners works best. Make sure to use enough cushioning inside to protect fragile contents from shocks or drops.
If your package is late compared to the expected delivery date or tracking shows it's delayed in transit, contact USPS to open an investigation. If deemed lost, you can file a claim for the value of the contents.
