An Post has said post offices will remain open and postal services will operate as normal in the coming weeks.
The postal service will continue to deliver letters and parcels, but delivery times may vary as it tries to facilitate flexible working times for staff.
Collection services will also operate as normal.
An Post has been working closely with the HSE expert team, and it advises that there is no evidence of a risk of contracting the virus that causes Covid-19 by handling money, mails or parcels.
The company said special arrangements for post office customers unable to collect their pension payments are now in place. A nominated temporary agent may collect the payment on their behalf, on production of necessary ID and documentation
"At this difficult time for everyone, our objective is to ensure the health & safety of staff, the continuity of business for An Post's customers and to assist the national effort wherever possible" said An Post CEO, David McRedmond.
