And it's only getting busier in the build up to Christmas.
Midlands mail centres are currently processing two million letters a day.
Over the Christmas period, An Post's Portlaoise hub sorts up on 600,000 small parcels every week.
While Athlone Mail Centre receives 400,000 a week.
The postal service expects that to increase further over the week ahead, as we inch closer to Christmas.
Trina Murray from Moate Post Office says they're already handling large volumes:
