A mail carrier gets the right mail to the right door, safely and on time, and treats customers well while doing it. You do not need a degree. You need reliability, a clean driving record, good physical stamina, and the ability to pass the USPS hiring process. This roadmap takes you from learning how the job works, to getting hired as a City Carrier Assistant (CCA) or Rural Carrier Associate (RCA), to becoming a regular carrier who runs a route efficiently and may move into other postal roles. Every resource here is free, and most of the learning happens by doing, so the drills below matter mos

Stage 1 of 3 · about 4 weeks
Understand what carriers do each day, meet the basic requirements, and build the habits that get you through the hiring process.
Know the job and the requirements
If you know the job's real demands before you apply, you can prepare for them and avoid surprises. USPS requires applicants to be 18 or older (16 for some jobs, but carriers are generally 18), a US citizen or lawful permanent resident, and to pass a background check, drug screen and, for driving positions, a driving record review. Men born after 1959 must be registered with Selective Service.
Physical stamina and safe lifting
Carriers walk several miles, climb steps, and carry satchels and parcels in heat, cold, rain and snow. USPS requires you to be able to lift up to 70 pounds and carry up to 35 pounds. Building stamina early prevents injuries, which are the biggest threat to a carrier's career.
Reading addresses and understanding delivery basics
Most delivery errors come from misreading an address. You must understand street numbers, odd and even sides, apartment and suite numbers, ZIP+4 codes, and standard abbreviations, because these decide where each piece goes.
Safe driving and defensive habits
Many carriers drive a postal vehicle, often a right-hand-drive one, making frequent stops. Crashes and a poor driving record can end your application, so you need strong defensive driving habits first.
