How to File a Missing Mail Search Request with USPS

Step 1: Mail all the Information

The next page can take a few times to get loaded. Once it completes loading, you can start by providing the tracking number of your package. After entering the tracking number, if USPS apprehends it, then USPS will auto-fill the date of your mail and the type of service. If that doesn’t happen, you can find that data on Pirate Ship, as well.

USPS operates all of the claims of insurance internally. If you’ve purchased some labels on Pirate Ship, and you ask for insurance, their answer would be “No”.It asks if you have bought added insurance through USPS because this is available only if you purchased the labels directly through them.

Hence, USPS doesn’t go along with the third-party insurances that are done using Shipsurance because these kinds of built-in insurances are available only on Priority Mail shipments.

Calculating Your Package's Cubic Tier

For Boxes and Rigid Packages:

  3. Multiply length x width x height
  4. Divide the result by 1728 (cubic inches in a cubic foot)
  5. The result is your package's cubic feet measurement

Example: For a box measuring 12.3" x 9.5" x 3":

  1. Round down to 12.25" x 9.5" x 3"
  2. 12.25 x 9.5 x 3 = 349.125
  3. 349.125 / 1728 = 0.202 cubic feet
  4. This package falls into the 0.3 cubic feet pricing tier

Note: Maximum size for any single dimension is 18 inches

For Envelopes and Soft Packs:
  1. Measure the length and width of the empty envelope

    • Tier 0.3: 27.01" to 31"
