I have a 2006 Z06. On the glovebox door is the Service Parts ID label with 43 RPO Code numbers listed. I can decode most of them from the information found in the 2006 Service Manual. However, the following codes are not listed in the manual. Does anyone know what these codes stand for? The codes are E2C, IL3, R6P, R9N, R9Z, SLL, 1SZ AND 19U. Appreciate any assistance you can provide.

19U is your paint code - LeMans Blue Metallic

I'll take a stab. Remember, sometimes the codes are year and or model specifc, so these could be off, plus some are not too descriptive, but it's a start:

RPO codes from GM:

E2C= Expedite to customer - sold order

R9Z - Control - Sales Item #100 *Processing Option*

SLL - Sales Processing

19U - PRIMARY COLOR, EXTERIOR (Black)

R6P - CONTROL , SALES ITEM #15 (special paint?)

IL3 : TRIM INTERIOR DESIGN, (Level 3)

R9N - Control sales item (???)

1SZ - Discount option package

[edited to add - here is an example of not matching up -- for many years, 19U indicated black. Apparently not on the C6:]

* 10U Arctic White
* 19U LeMans Blue Metallic
* 41U Black
* 45U Velocity Yellow Tintcoat
* 67U Machine Silver Metallic
* 74U Victory Red
* 80U Monterey Red Metallic
* 83U Atomic Orange Metallic Tintcoat

Edited again to add following -- looks like 19U is black, but not for C6 Corvette:
