Kirkham Post Office is to get extended opening hours following a revamp.
The facility on Market Square will shut from November 8 to 23 to allow the upgrading work to take place.
When it relaunches, the post office will be Monday to Saturday from 9am to 5.30pm, with a service point in the store open seven days a week.
Kirkham Post Office will continue to have five serving positions - two screened and two open plan and a counter positions and a service point.
Post Office regional network manager, Adrian Wales, said: “We understand how important having a Post Office is to residents in the area and we are confident that this new modern Post Office service will meet the needs of the local community and secure services for the future.
He added: “The modernisation is part of a major investment programme to convert the Post Office network to new-style branches and this investment, the largest in the history of the Post Office, marks a commitment to no more branch closure programmes.”
The nearest alternative post offices are in Freckleton and Wesham.
