play configurations that are required 
to be displayed are lost, damaged or de-
stroyed during transportation, the car-
rier shall replace all the missing or 
damaged identification numbers as

case, the numbers may be entered by 
hand on the appropriate placard, or-
ange panel or white square-on-point

cated in the white display area speci-
fied in § 172.332. This section does not 
preclude required compliance with the 
placarding requirements of subpart F 
of this subchapter.
