Residents, businesses and groups are being encouraged to give their views on plans to create a single council for West Suffolk.
St Edmundsbury Borough and Forest Heath District Councils are looking at creating the new authority in time for local elections in May 2019.
Bosses say a single council would be more financially resilient and have a greater national influence.
People are invited to have their say on the plans to help shape a final business case, which will be presented to both councils in September.
Cllr James Waters, leader of Forest Heath, said: “We want to hear the views of our communities and businesses to help us inform the debate we will be having in September and shape the business plan.”

People can also email their views to email@example.com
A proportionally representative phone poll is also due to be carried out in the next month.
