To file a complaint against a USPS employee, use the “Email Us” form on usps.com, call 1-800-ASK-USPS (1-800-275-8777), or go to the local post office and ask to speak with the station manager. Which route fits depends on what happened. Routine service problems — a rude clerk, a carrier who mishandles packages, a missed delivery — go through those three channels. Mail theft, fraud, or identity theft tied to your mailbox goes to the U.S. Postal Inspection Service. Internal misconduct like bribery, embezzlement, or narcotics trafficking goes to the USPS Office of Inspector General.
What to Have Ready Before You File
A complaint moves faster when a supervisor can pin down exactly who and what you’re talking about. Vague reports stall.
Gather the date and approximate time of the incident, the address of the post office or delivery location, and a plain factual description of what happened. If a package is involved, have the tracking number in front of you. If you can identify the employee by name, badge, or employee ID, include it. When those aren’t available, note physical details and any distinguishing uniform features.
Write your account in chronological order before you submit it. Stick to what you observed. “The carrier threw my package over the fence” is useful; “the carrier doesn’t care about their job” isn’t. Keep copies of everything you send until the matter is resolved.
Filing Online
The main online channel is the USPS “Email Us” page. You select a topic under “What’s the reason for your inquiry?” from categories that include delivery issues and complaints about employees or facilities.1USAGov. How to File a U.S. Postal Service Complaint The form walks you through structured fields for your contact information, tracking number, facility location, and a text box for the description. Fill every applicable field. Incomplete submissions are more likely to get flagged or ignored.
Filing by Phone
Call 1-800-ASK-USPS (1-800-275-8777). The Customer Care Center is open Monday through Friday, 8 a.m. to 8:30 p.m. ET, and Saturday, 8 a.m. to 6 p.m. ET.2USPS. Contact Us When the automated system picks up, say “agent” or “complaint” to reach a live representative. Ask the agent to read your details back before finalizing the entry. A phone submission creates the same electronic record as the online form and reaches the same regional management team.
Filing in Person With the Station Manager
You can walk into your local post office and ask to speak with the station manager.1USAGov. How to File a U.S. Postal Service Complaint For routine delivery problems this is often the fastest path, because the manager oversees the carriers and clerks at that location and can investigate right away. Bring the same documentation you’d use online: dates, tracking numbers, and a written summary. Ask the manager to document your complaint formally rather than treating it as a casual conversation, so there’s a record if you need to escalate.
Reporting Mail Theft or Fraud
If your complaint involves stolen mail, mail fraud, or identity theft connected to your mailbox, the U.S. Postal Inspection Service is the right agency. This is the law enforcement arm of USPS, staffed by federal agents with the authority to investigate and prosecute mail crimes. The scope covers everything from a carrier stealing packages off a route to organized fraud schemes conducted through the mail.
Report online at uspis.gov/report or call 1-877-876-2455.3USPIS. Report The website organizes reporting forms by crime type. If you witness a crime in progress, call 911 first and file the Postal Inspection Service report afterward.
The penalties on the other end are serious. Under federal law, a postal worker who secretly takes, destroys, or intentionally delays letters, packages, or other mail can be fined and imprisoned for up to five years.4Office of the Law Revision Counsel. 18 USC 1703 – Delay or Destruction of Mail or Newspapers A separate statute covers employees who steal articles from the mail, with the same five-year maximum.5Office of the Law Revision Counsel. 18 USC 1709 – Theft of Mail Matter by Officer or Employee
Reporting Internal Misconduct to the Office of Inspector General
The USPS Office of Inspector General investigates misconduct that goes beyond ordinary service complaints: embezzlement, narcotics trafficking, bribery, workers’ compensation fraud, and other abuses of a postal employee’s position. These investigations operate under the Inspector General Act of 1978, which gives the OIG independent authority to investigate without going through local management.6Office of the Law Revision Counsel. Inspector General Act of 1978
File through the OIG’s online hotline form at hotlineform.uspsoig.gov and select “Report Fraud, Waste, and Abuse.”7Office of Inspector General OIG. File an Online Complaint You can also call 703-248-2100.8Office of Inspector General OIG. Contact Us Reporting here bypasses local postmasters and puts the matter in front of federal investigators.
You can ask that your identity be kept confidential, or file anonymously without providing your name at all. Two caveats: if your identity turns out to be essential to the investigation, the OIG may have to reveal it, and complaints sent by ordinary email rather than through the secure online form can’t be guaranteed confidentiality because of how email systems work.9Office of Inspector General OIG. Frequently Asked Questions
Escalating When the Local Response Doesn’t Fix It
If the local postmaster’s response doesn’t resolve the problem, the next step is USPS’s District Consumer Affairs office. These offices exist to handle service issues that local management couldn’t fix.10Postal Regulatory Commission. Consumer Assistance You can find the office for your area through the USPS Consumer Affairs locator at postalpro.usps.com.
If the internal process still leaves you unsatisfied, contact the Postal Regulatory Commission. The PRC is an independent federal agency that oversees USPS compliance with postal laws. When you submit a service inquiry, the PRC documents it and may forward it to USPS, which then has 45 days to investigate and respond to you directly.10Postal Regulatory Commission. Consumer Assistance
The PRC also has a formal complaint process for persistent or systemic problems, but that’s a legal proceeding that typically requires an attorney and isn’t the right tool for a single missed delivery. Where a pattern of misconduct affects many customers or a significant region, the Commission can investigate, appoint an independent investigator, order corrective action, and impose fines if it finds deliberate noncompliance.11eCFR. Part 3022 – Rules for Complaints
Refunds Are a Separate Track
A complaint about employee conduct and a claim for a refund are two different processes. If a postal worker’s actions cost you money on postage or a paid service, you can pursue a refund independently, and you shouldn’t wait for the complaint to resolve first. USPS offers refunds when postage or fees were incorrectly charged, when paid services weren’t provided, or when non-delivery was USPS’s fault, with proof of purchase such as a tracking number or receipt.12USPS. Request a USPS Refund – Domestic Deadlines vary by service, and Priority Mail Express carries a money-back guarantee tied to the delivery time on your receipt. For damaged items or missing contents, the claim deadline is 60 days from the mailing date.13USPS. File a USPS Claim – Domestic Missing these windows means losing the reimbursement.
What to Expect After You File
Once you submit a complaint through any USPS channel, the system generates a case number that serves as your permanent reference. If you filed online through a USPS.com account, updates appear under Claim History and you can opt in to email notifications.13USPS. File a USPS Claim – Domestic Keep the case number regardless of how you filed. You’ll need it for any follow-up call or escalation.
Management at the relevant facility reviews the complaint, checks internal logs, and typically interviews the employee involved. They may contact you to clarify details or explain what corrective steps they’re taking. Outcomes range from informal coaching to formal discipline like a letter of warning or suspension. For complaints routed through the PRC, USPS has 45 days to investigate and respond.10Postal Regulatory Commission. Consumer Assistance
One realistic expectation to set: USPS generally won’t tell you the specific discipline the employee received. Federal employee privacy rules limit what management can share with a complainant about internal personnel actions. What you should get is an acknowledgment that the complaint was investigated and a description of what USPS is doing to keep the problem from recurring.
