Services will be transferred to the nearest alternative Post Office
An Post has released a list of 159 Post Offices that will close in the coming months, including which will affect Carlow customers.
The closures are part of a deal reached between An Post and the Irish Postmasters' Union which sees 159 postmasters retire and their offices close.
A voluntary retirement package was offered earlier this month to postmasters.
Post Offices in Crettyard and Rathtoe have been named as part of the closures list, according to An Post.
Services will be transferred to the nearest alternative Post Office.
Customers in Crettyard will have to go to Castlecomer which is 7.1km away but there are also Post Offices in Bilboa, Ballylinan and Carlow that are within 15km away.
Customers in Rathtoe will have to travel 5.2km to Tullow but there are also services in Staplestown Rd, Fenagh, Carlow, Myshall and Rathvilly which are all within 15km.
The changes will affect post offices all over the country.
They say that all of the offices which are due to close are within 15km of at least one other post office.
An Post also said that all are in locations with populations of less than 500 people.
Closing Post Offices will be consolidated with neighbouring offices, ensuring their viability, the company has said.
An Post says: "All remaining Post Offices will benefit from enhanced services and products, new opening hours and an investment package aimed at improving services for customers, driving customer footfall and attracting a wider demographic to ensure that the post office is not just wanted by communities but is indeed relevant and actually used by all."
Debbie Byrne, managing director of An Post Retail, said, An Post was "committed to ensuring the sustainability and viability of the Post Office network and would move now to offer more new and innovative services to customers through the reconfigured network."
"An Post is very grateful for the contribution of the Postmasters over so many years. We will work with the communities that they have served to ensure that their needs continue to be met by An Post for the future," she added.
"The An Post team has done painstaking work combining business and demographic data with extensive local knowledge to produce a network plan which actively supports the future of rural Ireland."
"We are committed to ensuring a vibrant network for all our customers through investment and the expansion of e-commerce, financial and government services to drive usage and relevancy of the post office in today’s changing environment".
