Frequently Asked Questions

Quick answers to common questions about freight forwarder detection.

A freight forwarder is a business that receives packages on behalf of overseas buyers and reships them internationally — often to countries where the original seller doesn't ship. While freight forwarding itself is legal, it creates serious problems for sellers: you lose control of your product, warranty obligations become impossible to enforce, and you may unknowingly violate distribution agreements. Many forwarders operate out of commercial mailbox services or suite-style addresses that look like regular residential or business locations, making them difficult to spot without a dedicated detection tool.
Shipping to freight forwarders exposes your business to significant financial risk. Once a product leaves your hands through a forwarder, you have no way to honor returns, replacements, or warranties — yet you're still legally responsible. Chargebacks from forwarded orders are nearly impossible to dispute because the tracking shows successful delivery. Products are often resold in unauthorized markets at prices that undercut your authorized distributors, damaging your brand and channel relationships. For high-value items, even a single forwarded shipment can erase the profit from dozens of legitimate sales.
Our database currently contains hundreds of known freight forwarder and mailbox service addresses across 12 U.S. states, compiled from our own research. While no detection system can guarantee 100% coverage — new forwarders open and close regularly — matching against a curated list of known locations catches the most common repeat offenders. Each result includes a confidence score so you can make informed decisions about borderline cases, and we recommend flagging any address that scores above your risk threshold for manual review.
Free and Pro tier users: this service is provided "as is" without warranty. We do not assume liability for business losses resulting from flagged or unflagged addresses. Enterprise customers receive custom terms and dedicated support with explicit liability terms negotiated during onboarding. For businesses shipping high-value items, we recommend using our service as one signal among many in your fraud prevention workflow, not as a sole decision-making source.
