Concerns about the proposed new Eircode postcode system will be discussed later today.
Officials from the Department of Communications and Capita Business Support Services Ireland - the company responsible for rolling out the system - will appear before the Committee on Transport and Communications.
The new system will be implemented across the country from next year.
Deputy John O’Mahony, the Chairman of the Committee, says today's meeting will give all sides an opportunity to respond to any criticisms.
He said: "The role of the committee is to hear all sides of this debate so that there will be a clear view as to whether this postcode system will be successful and meet the needs of the Irish people.
"I think that needs to be done in advance of it being rolled out which is next year, and if it is then, that people will be educated to the advantages of the system."
