NATIONAL League main sponsor Vanarama will continue its partnership with non-League's top flight for a further three seasons.
The deal extends to 2024/25 the company's title sponsorship of the National League, which has existed for 11 years.
Earlier this year, National League clubs voted to continue the season, although National League South and North clubs did not.
Matchday revenue is significantly down due to the absence of spectators, meaning streaming has become the main source of income on Saturdays.
Clubs are struggling financially in lockdown, with Dover Athletic, King's Lynn, Weymouth and Chesterfield all furloughing players.

It follows a reported £110m commitment from BT Sport to remain official broadcaster of England's fifth division up to the end of the 2023/24 campaign.
Since taking over title sponsorship in 2014, Vanarama has actively raised the profile of the league through innovative campaigns such as MANarama which helped raise over £200,000 for Prostate Cancer UK.

During the Covid pandemic Vanarama set up a Covid-19 support helpline for National League clubs and local businesses applying for any of the Government financial schemes.
Chairman of the National League, Brian Barwick OBE, said: “We are delighted to continue our title sponsorship with Vanarama and thank them for their steadfast support during the past 12 months.

“This enhanced arrangement will take our partnership up to 11 years. That speaks volumes about the confidence we both have in each other.
“The National League has found a great organisation to work with and we are pleased Vanarama find the relationship to be equally rewarding.
“We all look forward to four more years growing our unique partnership”.
The deal is significant for Weymouth as all National League clubs earn revenue from the governing body.
“We’re delighted to continue our relationship with The National League,” Vanarama CEO Andy Alderson added.
“We have a great affinity for this level of football as it really helped us accelerate the growth of our commercial van leasing business back in 2014.
"Now in 2021 having just launched our new brand campaign we’re breathing a new lease of life into our sector.
“As we undergo huge growth across our personal car leasing business, we wanted to show our commitment to do the same for grassroots football.
“The clubs and communities at this level have gone through very hard times, we hope that our investment will offer some stability and hope as we all work through the covid pandemic together.”
