All Post Offices statewide will be open Christmas Eve.
However, many will shorten retail lobby hours to allow employees to spend more time with their families.
The Brazil Post Office will close early on Christmas Eve and New Year's Eve. It will open at 8 a.m. but close at 2 p.m.
The office will resume normal business hours following the holidays.
"We will make our last collection for mail deposited in blue collection boxes on Dec. 24," Brazil Post Office Postmaster Dianna Egold said.
Egold said commercial customers should check with their bulk mail acceptance unit for Dec. 24 hours of operation.
Regular mail delivery for Christmas and New Year's Eve will be unaffected by the change in hours.
However, Egold said the Brazil Post Office will be closed Christmas Day, but Express Mail will be delivered. Regular mail delivery will resum Dec. 26.
