Launched on 1 July, the All York ticket will be valid on all services.
The authority said it was also working to replace paper-based tickets with a single electronic smart ticket.
The launch of the 'All York' ticket builds on the council's commitment to 'Get York Moving' and to improve the city's public transport services.
Cllr Dave Merrett, Cabinet Member for Planning, Sustainability and Transport, said: "One of the commitments of 'Get York Moving' was to introduce a single ticket that could be used on all operators' bus services, and this is now just about to become a reality.
"So, this event is a first milestone, following many months of negotiations, on the road towards a simpler, more user friendly bus service for York. It will be the first time a single ticket can be used on all local services, and will give all working age residents a new alternative to the car for many more local trips".
The 'All York' ticket can be purchased on any bus in the city and will go on sale from Sunday 1 July.
Two products will be launched on this date:
- All York Day (£5 - adult day ticket)
- All York Family (£10 - a day ticket valid for up to five people, maximum two adults)
The 'All York adult day ticket is to be launched at an introductory price of £4.50 which represents excellent value and is significantly cheaper than buying return tickets with two different bus operators.
York bus operators include:
- East Yorkshire Motor Services
- Eddie Brown Tours
- First York
- Harrogate Coach Travel
- Stephensons of Easingwold
