X12 124 — Vehicle Damage

The 124 documents damage observed on a vehicle during transport or at delivery: damage type, affected area, severity, liability.

Purpose

The 124 is used in finished vehicle logistics — flows from plants to dealerships: it carries the VIN, the responsible carrier, the damage nature (scratch, dent, broken glass), the area of the vehicle following AIAG (Automotive Industry Action Group) nomenclature, severity (severity code 1-5), and cost estimate.

It feeds OEM claims tools (Ford CVL, GM Logistics) and carrier tools (Jack Cooper, United Road). Acknowledged by 997; downstream financial claims flow through 859 (Freight Invoice) or 824 (Application Advice).

Envelope structure

The 124 travels within the three X12 envelope levels (ISA/IEA, GS/GE with functional group VD, and ST/SE). Didactic example in release 004010:

Common segments

  • HeaderST, B1 (Beginning Segment for Booking or Pick-up / Delivery), A = report action.
  • Vehicle referenceN9*VN (VIN), N9*OD (Destination Dealer Code).
  • DamageLX loop: N9*ZZ (AIAG area: 8 = front fender left, 6 = hood, ...), N9*ZZ (severity 1-5), MSG (free-text description).
  • ActorsN1*CA (Carrier) if origin is not the shipper.
  • SummarySE.

Common pitfalls

  • Exact 17-char VIN: a truncated or mistyped VIN misses the vehicle correlation at the OEM; always validate the VIN check digit (position 9) before sending.
  • AIAG area code: use the AIAG Damage Area Code Manual; home-grown codes break correlation with OEM dashboards and carrier scorecard statistics.
  • Severity vs cost: severity 1-5 is subjective (1=minor cosmetic, 5=major mechanical); a severity 2 may cost 50$ or 500$ — always pair with an AMT cost estimate.

Documentation

The code 124 and the name Vehicle Damage 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.
