Young people aged 16-21 can get a free mytravelpass for £1 bus fares starting September 1st.
Single fares will be £1 and day tickets £3, with unlimited travel on participating buses.
Cabinet Secretary for Transport and North Wales Ken Skates said: "This scheme will make a real difference to young people across Wales, and will allow them to make journeys for work, education and leisure at a discounted price.
"I would encourage those who don’t yet have a mytravelpass to apply so they can take full advantage of the scheme when it begins in September."
Full details of the scheme are available on the mytravelpass website.
£15m is being provided over two financial years (2025-26 and 2026-27) to support £1 bus fares for 16 to 21-year-olds as part of the Budget deal with the Leader of the Welsh Liberal Democrats Jane Dodds.
The Welsh Government will invest a further £7m to extend the scheme to five to 15-year-olds, from 3rd November.
