Wrong ZIP, wrong NMFC, wrong class, or a residential address flagged as commercial — any one of them and the carrier reprices, with the gap coming out of your margin. Free, no signup.
ZIP lookup
// one ZIP often maps to several acceptable city names; the wrong one reads as an address mismatch
▸ ZIP LOOKUP
Enter a 5-digit US ZIP.
NMFC code search
// search by commodity; a wrong code is the single most common cause of a rebill
▸ NMFC SEARCH
Type a commodity or a code.
Results are a reference. The same commodity can fall under different sub-codes depending on packaging or dimensions, and the carrier’s classification governs. We never invent a code that does not exist.
Density → freight class
// inches and pounds; for a pallet, use the palletized dimensions
▸ DENSITY / CLASS
Enter dimensions and weight.
Density is only a starting point. Actual class also depends on commodity, fragility, value density and each carrier’s own rules; where an NMFC code applies, the code’s class governs.
Residential or commercial
// an unflagged residential delivery comes back as a residential surcharge
▸ ADDRESS CLASSIFICATION
Enter a full US address.
AI: describe it, get the code
// plain description works best when it includes packaging and condition

★ The model only picks from codes that actually exist in the NMFC database. It never invents one — an empty result is preferred over a fabricated code.
Confidence is the model’s own estimate, not a guarantee. The carrier’s classification governs — when in doubt, send us the candidates and we will look together.
// These run on the same address and code databases our own freight operation uses — not demo data built for this page.
Same classification library, same address logic — running thousands of times a day inside the system. The tools stay free and open. Ready to ship? Register and use the full flow.
