More than 40 post offices have been earmarked for closure in Herefordshire and Worcestershire.
If the plans go ahead 29 would shut completely and 13 others be replaced by "outreach services" such as a mobile post office visiting at set times.
Post Office Ltd named the branches as it launched a six-week public consultation period affecting the two counties and the West Midlands.
The public have until 7 October to give their views on the proposed closures.
The cuts are part of national plans to reduce the UK-wide network, which the Post Office said is making huge losses.
It wants to reduce the number of branches by up to 2,500, from its current level of more than 14,000.
Post Office Ltd said under the proposals announced on Wednesday, more than 99% of the area's population would see no change to their nearest branch, or would remain within one mile of an alternative branch.
