Since these seem to be frequently asked I figured I'd make this "master cart" to decode sticks haha. Feel free to comment if I missed anything or if things are incorrect and I'll edit this post so it's always fresh and up to date! Post your pictures of codes if you have any questions... Always neat to see different things.
I know there is a lot of info but PLEASE scroll through till you find your brand and READ. Mostly if not everything is answered 
Keep in mind if you don't see the curve on the stick, you cannot tell what it is by just the code. You'll have to compare for yourself or ask us here!
Bauer Pro Stock Codes
- Usually look like this:
0102-12 (Player ID-Revision Number)
82 (Flex)
G3 (Flex Profile/Actual stick)
- There are many codes and variations which is why you sometimes see the same starting letter but different numbers (usually this is a blade change/colour change/grip change. Usually a CIS/NCAA/Jr. stick)
- * SE's are more durable usually European models used usually by College and Jr teams with lower budgets. SE sticks are essentially Vapor XXXX sticks.
- Most codes that vary are due to blade changes.

Reebok/CCM Pro Stock Codes
- Usually look like this:

T (Shaft)
E006948 (Player ID)
V01 (Version of stick within the line) - Ex: TACK STICK - V01 (SMTack) - V02 (SVTack)
SC (Flex Profile) - Sometimes followed by a lowercase l or u, this calls out light or ultra light shaft weight)
- Anything that says H11, H14, H15 and so on is the curve identification number - stock patterns
CCM offers different flex profiles in their Tack line as well which will play different. Pictures are shown below but for example you can get an SVTack AND an SMTack.
For the RBZ line CCM has gone about putting SB (Speedburner) and SF (Superfast) behind the RBZ on the top of the stick. You will see RBZSB and RBZSF. Pictures below as well.
In most cases from 2015 on (unless listed RI on the Ribcore line) you will have exactly what LINE the stick is painted as. BUT you might not know if it's a Speedburner or a Superfast etc. you will know that it is an RBZ.
