Whitland Post Office closed temporarily in August 2022, following the resignation of the postmaster.
Whitland will now be added to the service from Tuesday, October 4.
The new Mobile service will operate from King Edward Street car park in Whitland, SA34 0AA, twice a week, on Tuesdays from 9.45 to 11.15 am, and Thursdays between 9.15 and 10.45 am.
The travelling Post Office is aboard a specifically designed vehicle. It is a tried and tested way of maintaining service to communities.
A spokesperson for the Post Office said that they were pleased to reinstate the service as a Temporary Mobile service whilst they continue to seek a ‘permanent solution’.
Post Office Network Provision Lead, Fiona Shanahan, said: “We are delighted to soon be able to restore service to Whitland as we know how important a Post Office is to a community.
“We thank the Postmaster for Kilgetty for adding this service.”
