Unlawful Mailing and Suspicious Packages: Defense of Charges Under 39 U.S.C. § 3001

If you have ever been to the post office to mail a package, you may remember the person behind the counter asking if your package contained anything that was flammable, toxic, hazardous, or otherwise potentially dangerous. You probably said, “No,” without giving it much thought, and perhaps without even listening to the laundry list of prohibited items. You probably also did not realize that misrepresenting the contents of your package would have been a federal offense, punishable under 39 U.S.C. § 3001.

Titled “Nonmailable matter,” 39 U.S.C. § 3001 is a lengthy statute that punishes a broad range of offenses related to the improper depositing of mail with the United States Postal Service (USPS). Offenses range from depositing hazardous materials to mailing solicitations that appear to be invoices or official government documents. The statute has been amended and expanded several times since its original enactment in 1970, and portions of the statute are known by short titles including:

  • Deceptive Mail Prevention and Enforcement Act of 2000
  • Deceptive Mailings Prevention Act of 1990
  • Drug and Household Substance Mailing Act of 1990
  • Mail Order Consumer Protection Amendments of 1983

Most investigations under 39 U.S.C. § 3001 involve the USPS and its law enforcement and security arm, the U.S. Postal Inspection Service. However, other agencies, including the U.S. Department of Justice (DOJ) may also be involved in mailing and shipping-related investigations. Penalties can be either civil or criminal in nature, and individuals and organizations targeted under 39 U.S.C. § 3001 will often face charges under the federal mail fraud statute, 18 U.S.C. § 1341, and other federal criminal statutes as well. As a result, if you have received a letter from the U.S. Postal Inspection Service, its Criminal Investigations Service Center, or any other federal law enforcement authority, it is imperative that you seek the best, most experienced defense counsel immediately.

Potential Allegations Under 39 U.S.C. § 3001

39 U.S.C. § 3001 is extremely broad in scope and, along with the federal mail fraud statute, it imposes penalties for all forms of improper use of the USPS mailing service. This begins with preparing mailings that violate the law, continues through unlawfully depositing packages with USPS, and culminates with receiving improperly-mailed shipments and communications. Some of the most common types of allegations under 39 U.S.C. § 3001 include:

  • Government Look-Alike Mail – Under Section (h) of 39 U.S.C. § 3001 (portion of the Deceptive Mailings Prevention Act of 1990), it is unlawful to send any solicitation, “which reasonably could be interpreted or construed as implying any Federal Government connection, approval, or endorsement through the use of a seal, insignia, reference to the Postmaster General, citation to a Federal statute, name of a Federal agency, department, commission, or program, trade or brand name, or any other term or symbol.” The only exceptions are for mailings that actually have an official government endorsement, that contain an appropriate disclaimer, or that are sent at the request of the addressee.
  • Illegal Sweepstakes Information – Under Section (k) of 39 U.S.C. § 3001 (portion of the Deceptive Mail Prevention and Enforcement Act of 2000), it is unlawful to use the mail to send information related to an illegal sweepstakes, lottery, or contest. Sweepstakes, lotteries, and contests advertised through the mail are subject to strict rules, and any solicitations must include specific information and disclaimers while avoiding fraudulent claims or misleading statements.
  • Fraudulent Mail Order Schemes – Fraudulent mail order schemes are prohibited under the Mail Order Consumer Protection Amendments of 1983. Sending advertisements, bills, and other materials designed to fraudulently solicit payment for falsely-advertised products or services can trigger steep penalties. Common allegations related to alleged fraudulent mail order schemes involve healthcare services, medications, fitness products, cosmetics, anti-aging products, sexual wellness products, and other schemes targeting personal appearance or wellbeing.
  • Fraudulent and Misleading Solicitations – Various provisions of 39 U.S.C. § 3001 apply to use of the mail to send other types of fraudulent and misleading solicitations. Specific prohibitions range from sending advertisements that look like invoices (materials which are, “in the form of, and reasonably could be interpreted or construed as, a bill, invoice, or statement of account due; but . . . constitute[], in fact, a solicitation for the order by the addressee of goods or services, or both.”) to sending, “unsolicited advertisement[s] of matter which is designed, adapted, or intended for preventing conception.”
  • Hazardous Material – Under Section (n) of 39 U.S.C. § 3001, it is illegal to deposit any “hazardous material” with the USPS. “Hazardous material” is defined in 49 U.S.C. § 5103(a), and includes, “an explosive, radioactive material, infectious substance, flammable or combustible liquid, solid, or gas, toxic, oxidizing, or corrosive material, [or] compressed gas.”

FAQs: Why am I Being Investigated Under 39 U.S.C. § 3001?

Q: Why did I receive a letter from the U.S. Postal Inspection Service?

If you have received a letter from the U.S. Postal Inspection Service or its Criminal Investigations Service Center, you may be under investigation under 39 U.S.C. § 3001. To determine the allegations against you, you will need to parse key information from the letter, and it may be necessary to contact the U.S. Postal Inspection Service directly. Both of these are tasks that should be handled by the best federal defense counsel, as mistakes during a government investigation can have drastic consequences – including the potential for facing charges that could have otherwise been avoided.

As far as why the U.S. Postal Inspection Service or its Criminal Investigations Service Center is investigating you, there are a variety of potential triggers. Investigations under 39 U.S.C. § 3001 are often triggered by factors such as:

  • Electronic scans of letters and packages deposited with the USPS for mailing;
  • Physical inspection of letters and packages deposited with USPS;
  • Statements or testimony from alleged co-conspirators or other parties under investigation; or,
  • Complaints from consumers, patients, or other mail recipients.

Q: What should I do if I am being investigated under 39 U.S.C. § 3001?

If you are facing a federal investigation under 39 U.S.C. § 3001, including provisions of the Deceptive Mail Prevention and Enforcement Act, the Deceptive Mailings Prevention Act of 1990, the Drug and Household Substance Mailing Act of 1990, or the Mail Order Consumer Protection Amendments of 1983, the most important thing you can do is to seek experienced legal representation immediately. You need to take proactive measures to defend yourself, and you need to avoid costly mistakes that could jeopardize your defense. The best federal defense attorney will be able to communicate with U.S. Postal Inspection Service agents on your behalf and gather the information needed to protect you against dangerous federal charges.

Q: What are some potential defenses to allegations under 39 U.S.C. § 3001?

The defenses that are available in any particular case under 39 U.S.C. § 3001 will depend on the specific provisions of the statute and the specific factual allegations involved. Broadly speaking, however, some potential defenses to charges involving improper use of the USPS include:

  • Innocence – You did not actually send “nonmailable matter” in violation of 39 U.S.C. § 3001.
  • Lack of Evidence – Federal authorities do not have the evidence they need to meet their burden of proof in a civil or criminal case.
  • Constitutional Protections – Evidence against you was obtained in violation of your constitutional rights and is therefore inadmissible in any case against you.

Q: Who is most likely to be targeted in an investigation under 39 U.S.C. § 3001?

While some investigations under 39 U.S.C. § 3001 target scam artists who intentionally use fraudulent mailings to solicit money from unsuspecting consumers, many investigations under the statute target legitimate businesses. For example, a product-based business might be targeted for offering a giveaway that fails to comply with the Deceptive Mail Prevention and Enforcement Act of 2000, or a healthcare provider or other service provider might be targeted for sending mailings that violate technical provisions of the statute.
