The abbreviation OFC is commonly used in Bulgarian sports contexts to denote Obshtinski Futbolen Klub (Municipal Football Club). Combined with Karnobat, the name could plausibly refer to a municipal football club based in the town of Karnobat, a settlement in Burgas Province, southeastern Bulgaria.
