The Post Office has selected a franchise operator for three of its branches in the region.
RF Retail will run the branches in Goodhart Road in Bransholme, Hull; Quay Road in Bridlington; and Victoria Street in Grimsby.
Six Post Office branches and six banking hubs are currently run by the company.
Last month, the Post Office announced it would offload the remaining 108 branches it directly owned and move to a fully franchised network.
