Sellers underpaying postage is not theft

Question asked:

“Sellers cheaping out on postage to retain more income is a tale as old as time. But definitely theft.”
Not theft
Confidence: High Checked on August 31, 2026

Summary

Sellers who use insufficient or counterfeit postage are violating postal regulations and may be committing fraud, but the act is not legally defined as theft. The USPS can collect the missing postage and impose penalties, but it is treated as a postage‑due issue rather than criminal theft.

  • Underpaid Postage--What Would You Do?

    Just received a 1-pound net weight item from a FBM seller and noticed it was First Class Mail. When I weighed it at home it registered 1 pound 2 ounces. What is troubling (fraudulent), is the label shows a weight of 4 ounces. The seller only has less than 10 feedbacks.
