WoW character

Hay guys I tried to update my WoW Character profile as per the instructions below

Enter one character per line.

Format: US/EU|Realm|Faction|Name

Example: US|Madoran|Alliance|Baylen

My Characters are mostly on oceanic servers and I entered OC|frostmourne|horde|hoocha

I dont think OC is correct for oceanic so if anyone knows the correct abbreviation for oceanic for this area please advise.

Cheers

US/EU is for which Armory your character profile is found under. There is no Oceanic armory, you fall under US.

cheers
