I differentiate between a COPO package and a Central Office approval.
A COPO package required a special combination of features and included delete and add instructions for the plant and was assigned a COPO #.
A COPO approval was 'build it without stripes or in this color or with this RPO' type of thing. No COPO # was assigned.
I believe I've seen Central Office approval mentioned in GM documentation. COPO packages are not.
The COPO's have a COPO # on the build sheet because they were a package. Never seen a special paint car with a COPO # on the build sheet, just the special paint instructions.

Comments Jim?
