of Level 5 divisions. This is a result of the uneven number of teams in the various oblasts of the country. For example, While the Burgas Oblast can sustain four Level 5 OFGs that are funneled into one Level 4 OFG, clubs from Smolyan and Lovech are enough to form only one division at one level so these oblasts have no Level 5 OFGs. Still, some of the "provinces" such as Blagoevgrad have five Level 4 divisions, but no Level 5 oblast groups. Regions The list includes a categorisation of teams by region of the country. The most reliable geographical categorisation of football clubs in Bulgaria has been the division of the clubs into four regions - those of V Group: North-West, North-East, South-East, and South-West, since it has been the sole constant division since the creation of the football pyramid in 1953. The regions' borders are the administrative borders of the state's "provinces" (oblasts) that constitute the regions. For the North-West region the included oblasts are: Vidin Province, Montana Province, Vratsa Province, Lovech Province, Pleven Province, Gabrovo Province, and Veliko Tarnovo Province. Veliko Tarnovo is the administrative center of the North-West zone for V Group. For the North-East region the included oblasts are: Razgrad Province, Ruse Province, Targovishte Province, Silistra Province, Shumen Province, Dobrich Province, and Varna Province. Varna is the administrative center of the North-East zone for V Group. For the South-East region the included oblasts are: Burgas Province, Yambol Province, Sliven Province, Stara Zagora Province, Haskovo Province, Kardzhali Province, Smolyan Province, and Plovdiv Province. Plovdiv is the administrative center of the South-East zone for V Group. For the South-West region the included oblasts are: Pazardzhik Province, Blagoevgrad Province, Kyustendil Province, Pernik Province, Sofia Province and Sofia - city. Sofia is the administrative center of the South-West zone for V Group. All Teams References Bulgaria Football clubs clubs
