Understanding the U.S. Postal Inspection Service and Its Role
The U.S. Postal Inspection Service (USPIS) is the law enforcement agency for the United States Postal Service. Established in 1772, it stands as one of the oldest federal law enforcement agencies in the nation. The USPIS employs approximately 2,300 people, including postal inspectors, forensic specialists, and administrative staff who work across the country.

The primary mission of the Postal Inspection Service is to protect the postal system and the public from mail-related crimes. This includes investigating mail theft, mail fraud, identity theft that involves the mail system, and other criminal activities that use postal services. The agency also works to ensure the safety of postal employees and facilities.
When you contact the Postal Inspection Service, you are reaching out to trained law enforcement professionals. These inspectors have the authority to investigate federal crimes involving the mail. They work with local police departments, the FBI, and other federal agencies to solve cases and protect mail users throughout the country.
Understanding what the Postal Inspection Service does helps you know when to contact them. This agency is not the same as your local post office or customer service for the USPS. While post offices handle regular mail delivery and customer questions, the Postal Inspection Service investigates crimes. Knowing this difference is important when you need to report a problem.
Practical Takeaway: The Postal Inspection Service is a federal law enforcement agency focused on mail-related crimes. If you suspect criminal activity involving the mail, this is the appropriate agency to contact rather than your local post office.
Types of Mail-Related Issues You Can Report
The Postal Inspection Service investigates a wide range of mail-related crimes. Mail fraud is one of the most common complaints they receive. Mail fraud occurs when someone uses the postal system to carry out a scheme to defraud people. This might include fake lottery winnings, fraudulent investment offers, fake shipping notifications, or scams promising money or services that never arrive.

Mail theft is another significant category of crime investigated by postal inspectors. This includes stolen mail from mailboxes, mail delivery vehicles, or postal facilities. Identity theft that involves stolen mail is also within their jurisdiction. When someone steals mail to obtain personal information for fraudulent purposes, this becomes a federal crime investigated by USPIS.
Threatening mail or harassment through the postal system falls under their investigative scope. If you receive threatening letters, obscene materials through the mail, or repeated unwanted mailings that constitute harassment, the Postal Inspection Service can investigate. They have authority to look into situations where mail is being used to intimidate, threaten, or harass individuals.
Other reportable issues include packages that never arrive at their destination, counterfeit stamps or postage, and mail containing drugs or other illegal items. If mail containing your medication, valuables, or important documents goes missing, USPIS can investigate. They also handle cases involving mailbox vandalism and theft of postal equipment.
Phishing scams and fake delivery notifications that direct people to malicious websites represent newer types of crimes the agency addresses. When scammers use postal service names or logos to trick people, this violates federal law. Lottery scams, romance scams, and work-from-home fraud schemes that operate through mail or use mail as part of the scheme are also investigable.
Practical Takeaway: Document what happened, including dates, descriptions of mail received or missing, and any communications from the suspicious sender. This information will be important when you contact the Postal Inspection Service.
How to Contact the Postal Inspection Service
There are several ways to reach the U.S. Postal Inspection Service depending on your needs and the urgency of your situation. The primary method for reporting crimes is through their online form at postalinspectors.uspis.gov. This website contains a form where you can report mail-related crimes. The online reporting system allows you to provide details about your situation and submit supporting information.

To use the online form, you will need to describe what happened, when it happened, and any relevant details. The form may ask for your contact information so they can reach you if they need more information. You can include descriptions of suspicious mail, information about who sent it, and what occurred. Having dates and times makes your report more useful to investigators.
You can also contact your local Postal Inspection Service office directly. To find the office nearest you, search for "Postal Inspection Service" plus your state or city on a search engine, or visit the USPIS website. Each state has at least one office, and larger cities may have multiple locations. Postal inspectors work during business hours, typically Monday through Friday.
When calling a local office, explain that you want to report a mail-related crime. Have your information ready, including dates, descriptions, and any documentation. The person who answers may direct you to the appropriate inspector or provide information about how your report will be handled. Calling ahead can sometimes ensure you reach the right person more quickly.
For emergencies involving imminent danger, contact local law enforcement or call 911. However, if the situation involves mail fraud or mail theft that is not an immediate safety concern, the online form or local office contact is appropriate. Some postal inspectors work with local police departments, so local law enforcement may also be able to direct you to the right federal agency.
Practical Takeaway: The online reporting form at postalinspectors.uspis.gov is available 24/7 and requires no special login. For faster response, also locate your local Postal Inspection Service office and save the number for future reference.
Information to Gather Before Contacting Postal Inspectors
Before you contact the Postal Inspection Service, gathering specific information makes your report more effective. Start by collecting all suspicious or relevant mail. Do not touch the mail with bare hands if it is suspected of containing drugs or dangerous materials, but do keep it in a safe place. Take photos of envelopes, postmarks, and the contents if safe to do so.

Write down dates carefully. When did you first notice the problem? When did you mail something, if relevant? When did you receive the suspicious item? What dates appear on postmarks or letters? Postal inspectors track patterns, so knowing the timeline helps them investigate. If multiple pieces of mail are involved, note each date separately.
Document the sender information visible on the mail. This includes return addresses, email addresses that appear on letters, website addresses mentioned in mail, phone numbers provided, and company names. Even if you suspect this information is false, include it exactly as it appears on the mail. Write down any person's name that appears in the mail or communication.
If money was involved, note how much and what method was used. Did you send cash, a check, money order, or make an online payment? If you wired money, include the company name and confirmation number if available. If you provided credit card information, note when you did so and watch your accounts for unauthorized charges.
Collect any tracking information, barcodes, or reference numbers from mail or packages. These numbers help postal inspectors trace items through the system. If you have emails, text messages, or other written communications related to the suspicious mail, save copies of these as well. Screenshots showing dates and times are useful.
Practical Takeaway: Create a simple document with three sections: Dates (when things happened), Sender Info (return address, names, phone numbers), and Evidence (what you received or lost). This organized approach makes reporting faster and clearer.
What Happens After You File a Report
After you submit information to the Postal Inspection Service, the agency reviews your report to determine if it involves a federal mail crime. Not all complaints fall within their jurisdiction. For example, if you received unwanted mail from a legitimate business offering products you do not want, this may not be criminal. However, if you received mail falsely promising lottery winnings or requesting payment for something you did not order, this likely is mail fraud.

The USPIS uses data analytics to identify patterns. Your individual report may seem small, but when combined with reports from others about the same sender or scheme, it creates a pattern that postal inspectors can investigate. Many successful investigations begin with multiple people reporting the same suspicious activity. If you received mail from a specific organization and others did too, your reports together build a case.
If your situation involves identity theft or financial fraud, postal inspectors may coordinate with
