In June 2018, the Executive Committee of the Bulgarian Football Union decided to increase the participating teams to 18 for the 2019–20 season; as a result, only two teams will be relegated to Third League.
FC Tsarsko Selo Sofia became champions of the second league and were promoted directly to the first division.
FC Dobrudzha Dobrich and PFC Nesebar were relegated.

Clubs in the domestic league can have more than one sponsorship per jersey which can feature on the front of the shirt, incorporated with the main sponsor or in place of it; or on the back, either below the squad number or on the collar area.
