The correct engine code is 4A-GE, but some people shorten it to 4AG since the E is redundant (ie they're all fuel injected, so they all have an E).
There is also 4A-C, 4A-F, 4A-FE and several others, but they're all different engines. There is no such thing as a 4A-GC.

I think the "U" indicates special tighter emissions gear that some cars in the US were fitted with. I don't think there are any of these "U" GE's in Australia.

"U" is for Japanese emissions, so you'll only see it on JDM engines.

And the 4AC will never be a 4AG as it is a single cam as opposed to twincam ...

To simplify this a little:
4A = engine type
F = twin cam narrow-angle (economy)
G = twin cam wide-agle (performance)
E = EFI
U = Jap emissions
C = Californian emissions

u is JDM and USDM
japanese and californian emissions regulation needs the emissions control marking and thats the U on the end
almost the same engine

I have an original rwd 4age (Bluetop) so mine is a 4ageu, i believe there are a few other's getting around.
You just here a lot about them.

What do you mean?
B means twin carbs but its relates to single cam desing for example 2T-B, 3K-B, 8R-B etc.
G means twin cam but also twin carbs if there's no E like 2T-G, 18R-G, 8R-G etc.
4A(-!)GB fights against the way that Toyota publicizes their engine codes. If there's such a thing.

so if what your saying is right, the 4AC has californian emissions? i think not
C would more likely mean it was Carby set-up rather than Electronic Fuel Injection (E)

Yes, the 4A-C has Californian emissions. Engines with Californian emissions weren't sold exclusively in California; I guess that particular emissions package just happened to pass Australian emissions requirements, so they just recycled it over here!
The C code has nothing to do with carbies; I can name a dozen carby Toyota engines with no C code.

You can only bump into L in FWD era engines, in other words E,A and S series engines.
L = lengthways installed engine. L is only for eighties stuff like 1. geneneration Camrys, Tercels and 4wd Corollas.

BEFORE "-":
the letters indicate the engine family, for example in 18R-G
the engine family is R, in 2JZ-GTE the family is JZ.
The number(s) at the beginning is the number of the are for a certain
bottom end version (block, bore, stroke). The larger the number,
the newer the bottom end version. It may seem like the larger the
number, the larger the displacement but this is not always true.
AFTER "-":
G = twin cam (wide angle, 45 degrees or more between the intake and exhaust valves)
F = "economical" twin cam (narrow angle, around 22 degrees)
T = turbocharged
Z = supercharged
E = fuel injection
i = single point fuel injection
L = transverse mounted engine (seems to be an obsolete code)
B = twin carbs (only used on non-twin cam engines, obsolete code)
R = air injection
S = swirl intake ports (only a few made in mid '80s)
S = direct injection & swirl pot pistons (starting from '97/98)
U = emission package (Japan)
C = emission package (California)
LPG = LPG fuel
