X12 466 — Rate Request

The 466 transmits a rail rate quote request from a shipper / 3PL to a railroad for a defined movement.

Purpose

The 466 documents the request for an applicable tariff to a specific movement: origin, destination, STCC commodity, equipment type, expected volume, period. It supports pre-booking quote comparison.

It typically triggers a 463 response. Acknowledged by 997. A request for multiple corridors or commodities flows via several distinct 466s for traceability.

Envelope structure

The 466 travels within the three X12 envelope levels (ISA/IEA, GS/GE with functional group GW, and ST/SE). Didactic example in release 004010:

Common segments

  • Header — ST, BGN.
  • Shipper / Railroad — N1*SH, N1*RR.
  • Route — N4 (origin), N4 (destination).
  • Detail — LX loop: NTE (STCC commodity), REF*ZZ (equipment AAR), QTY (cars or tons), DTM*002 (movement date).
  • Summary — SE.

Common pitfalls

  • Multi-rail interchange: a BNSF→UP move requires mention of the interchange junction (St. Louis, Memphis); otherwise the rate is not computable.
  • Full 7-digit STCC: use the full 7-digit STCC; a 5-digit STCC triggers a generic, non-commercial 463 response.
  • Volume signal: carrying actual QTY allows the railroad to offer a volume rate; a 466 without QTY gets the undiscounted tariff.

Documentation

The code 466 and the name Rate Request are public and listed on x12.org/products/transaction-sets. The complete structure of loops, qualifiers and code lists is distributed by DISA via the proprietary Implementation Guides (TR3). ediverse.io covers only public concepts, the envelope and didactic examples.
