X12 129 — Vehicle Damage
Specific damage report on a vehicle in transport: damage type, body-position (panel-by-panel), severity, estimated repair cost.
Purpose
Follows the 121 when a DA event is signalled. The 129 details the exact damage nature: hood, door-left, bumper-rear, etc. Each damage rates the vehicle zone (1-360 degrees per convention). Used for the insurance settlement between car hauler and manufacturer.
Envelope structure
The 129 travels inside the three X12 envelope levels (ISA/IEA,
GS/GE with functional group VD, and ST/SE).

Common pitfalls
- No photo: photo-less claims are rejected by 80% of insurers.
- Generic cost: AMT*TC = total, but many manufacturers want the breakdown (paint, part, labor).
- Non-standard zone: use SAE J1939 or AIAG standard for panel positions, not free text.
