What makes a package suspicious USPS?

In today’s world, where security concerns are more prevalent than ever, it is crucial to stay vigilant and be aware of potential threats. One area where this vigilance is essential is in identifying suspicious packages. Whether in transit or received at your doorstep, recognizing the signs of a suspicious package can play a vital role in ensuring the safety of yourself and those around you. In this blog post, we will explore the characteristics that make a package suspicious, the actions to take if you encounter one, and the importance of reporting these packages to the appropriate authorities.

Physical Characteristics of a Suspicious Package

One of the first indicators that a package may be suspicious is its physical appearance. Certain characteristics can raise red flags and warrant further investigation. Here are some key physical signs of a suspicious package:

1. Badly typed or written labels

Packages with labels that are poorly written, misspelled, or have illegible handwriting can be cause for suspicion. Professional counterfeiters or individuals with malicious intent may lack the attention to detail needed for proper labeling.

2. Unusual or excessive postage

Another physical characteristic to look out for is unusual or excessive postage. Suspicious packages often have an excessive number of stamps or postage, possibly indicating an attempt to avoid detection or divert attention from the package’s contents.

3. Lack of return address

A package without a return address raises suspicion as it suggests the sender’s desire to remain anonymous. While there may be legitimate reasons for omitting a return address, such as a surprise gift, it is essential to exercise caution when receiving packages without this information.

4. Strange or unfamiliar sender information

Packages from unknown or unfamiliar senders can also be a cause for concern. If the package does not include any recognizable sender information or if the listed sender seems suspicious, it is important to exercise caution and take appropriate steps to ensure your safety.

Unusual Content of a Suspicious Package

While physical characteristics can provide initial clues, the content of a package can further validate suspicions. Here are some unusual contents to be aware of:

1. Unknown powder or suspicious substances

Packages containing unidentified powders, liquids, or suspicious substances should be considered highly suspicious. These substances may pose health risks or be potential ingredients for harmful devices.

2. Offensive or threatening messages

Suspicious packages may include offensive or threatening messages, either written on the package or within its contents. Such messages indicate a potential threat or malicious intent and should not be taken lightly.

3. Suspicious objects or bulges in the package

Physical anomalies within the package, such as irregular bulges or the presence of wires, can be indicators of hazardous devices or other dangerous contents. If you notice any such objects, it is crucial to handle the package with extreme caution and report it immediately.

Origin and Transmittal of Suspicious Packages

Understanding where a suspicious package originates from and how it is transmitted can provide valuable insights into its legitimacy. Here are some key points to consider:

1. Packages mailed from a foreign country

Packages originating from foreign countries can be considered suspicious, especially if they are unexpected or have no apparent connection to the recipient. It is essential to exercise caution and carefully evaluate packages that fall into this category.

2. Packages with inconsistent or misleading return addresses

Packages with return addresses that are inconsistent with their claimed origin or have misleading information should raise concerns. This inconsistency may be a deliberate attempt to obscure the package’s true origins or destination.

3. Packages from unknown or suspicious senders

Any package received from an unknown or suspicious sender should be treated with caution. It is crucial to question the legitimacy of such packages and take appropriate steps to ensure your safety.

Actions to Take When Encountering a Suspicious Package

Encountering a suspicious package requires immediate action to protect yourself and others. Here are the steps to follow when faced with a potentially suspicious package:

1. Suspicion escalation protocol within USPS

If you are a USPS employee and suspect a package to be suspicious, you should follow the established protocol within the organization. This protocol ensures the safety of USPS personnel and provides guidelines to handle potential threats effectively.

2. Contacting law enforcement and relevant authorities

Regardless of whether you are a USPS employee or an individual receiving a package, it is crucial to contact local law enforcement and report the suspicious package. They have the knowledge and resources to handle such situations and ensure the safety of all involved.

3. Evacuation or isolation procedures

Depending on the assessment of the package’s threat level, local authorities may decide to evacuate or isolate the area. It is essential to follow their instructions diligently to minimize the risk to yourself and others.

Importance of Reporting Suspicious Packages

Reporting suspicious packages is not only a responsible action but also plays a significant role in maintaining security. Here’s why reporting is vital:

1. Preventing potential threats or harm

By reporting suspicious packages, you contribute to preventing potential threats and harm to yourself, your community, and the country as a whole. Early detection and intervention can save lives and prevent further acts of violence or terrorism.

2. Gathering intelligence and identifying patterns

Authorities rely on reported incidents to gather intelligence and identify patterns in suspicious activities. Your reports contribute to a larger database that helps law enforcement agencies identify trends and prevent future threats.

3. Enhancing national security efforts

Reporting suspicious packages is an essential part of maintaining national security. By actively participating in this process, you become an integral part of the broader effort to protect your country and its citizens.


Identifying suspicious packages is a vital aspect of maintaining personal and public safety. By paying attention to the physical characteristics and content of packages, as well as understanding their origin and transmittal, we can help prevent potential threats. Reporting any suspicions to the appropriate authorities not only ensures your safety but also enhances national security efforts. Remember, vigilance and reporting are crucial in today’s world, where even the smallest actions can make a significant impact. Stay safe, be vigilant, and play your part in protecting yourself and your community.
