Wrexham are hoping to secure funding to develop a 5,500-seat grandstand at the Kop end of their Racecourse Stadium.
The Wrexham Gateway project, which would see capacity increased to over 15,000, was announced in 2019.
Plans also include improving media, broadcast and projector facilities, parking and landscaping for a convention center and hotel.
Wrexham’s bid for a “stadium for the north” includes a mix of public and private funding.
The plans, backed by the club, Wrexham County Borough Council, the Welsh government and Glyndwr University will be considered for UK government funding this summer.
Wrexham is owned by Hollywood actors Ryan Reynolds and Rob McElhenney, who hopes to regain full ownership of Racecouse for the club.
Former Wrexham players Mickey Thomas and Malcolm Allen helped launch Wrexham’s campaign.
“Funding is vital if North Wales is to achieve its ambition of having facilities capable of hosting international sport,” said Thomas.
The campaign will run until mid-June and will provide information and communication that raises awareness of Wrexham Gateway’s application for funding.
Wrexham are currently pursuing promotion from the National League, having taken the lead in the division with a win over rivals Stockport.
