Route Inspections
Start strong as a new City Carrier Assistant, then learn how USPS route inspections work — and how to protect your route and your time.
Your first course covers two things in the order a new carrier lives them: getting started on the job, and then route inspections — how USPS evaluates your route, and how to protect your route and your time.
🚀 Getting Started as a New Carrier (CCA)
Here's what to expect in your first days, in the order it usually happens:
1. Your First Day on the Job
Report early, in uniform, ready to learn. You'll meet your supervisor, review your assignment, and get a quick introduction to the station's workflow.
2. Orientation and Safety Training
You'll receive safety briefings, essential forms, and an overview of USPS protocols. Pay close attention — safety is a top priority in every operation.
3. Getting Set Up at Your Station
You'll be assigned a case, issued a scanner and keys, and often shadow a veteran carrier. This is when you start learning the route and begin hands-on training.
4. Route Familiarization with Your OJI
Expect to walk or drive the route with an On-the-Job Instructor (OJI). Learn the "line of travel," dismount points, relay boxes, and safety concerns along the route. Take your time and ask questions — speed comes with experience; accuracy and safety come first.
Your day-to-day basics each have their own course: Daily Procedures, Habits & Routines, Timekeeping & Rings, Casing Mail, MDD Scanner Use, and Basic Rights & USPS Policies. For a printable first-weeks overview, see the CCA Onboarding Guide in Resources.
🧭 What Is a Route Inspection?
A route inspection is a formal USPS process used to evaluate the time, workload, and structure of a letter carrier's assignment.
The process typically includes multiple phases: office time review, street observations, and a final evaluation. Data gathered is used to adjust route times, assignments, and even route structures.
📅 The Inspection Process
- Notification: You should receive advance notice via Form 1838c or a stand-up talk.
- Data Collection: Includes DOIS data, office time, and PS Form 3999 (street observation).
- Observation Day: You'll be accompanied by a supervisor or manager while delivering your route.
- Adjustments: Based on the data, your route may be lengthened, shortened, or remain the same.
📄 Key Forms Involved
PS Form 3999
This is the official street observation form used to time you on your route. It captures actual times for each delivery segment.
PS Form 1838c
This form documents daily workload data, including mail volume, parcels, and time spent in-office and on street.
PS Form 3996
The form you use to request overtime or auxiliary assistance. Should be completed daily if you anticipate needing more time.
✅ Tips to Protect Yourself
- Fill out a 3996 every day if needed — it protects your route and documents your time.
- Be honest, not rushed: Don't speed up or change your behavior on observation day.
- Record your times: Keep a log using a Letter Carrier Workload Log or Daily Diary.
- Get a copy: Ask for your 3999 times after inspection day.
- Talk to your steward: They can help you file a grievance if needed.
