How to find and stop parcel shipping fraud

Refreshed on October 22, 2026

Summary

Parcel shipping fraud covers any shipment that moves on your carrier account, or carries your products, without your authorization. This article explains the main forms it takes, from stolen account credentials and label resale to employee misuse, label-based product diversion, slow-build schemes, and counterfeit labels, along with the warning signs of each and the controls that close the gaps.

Key takeaways

• Your parcel account works like a payment method, because carriers bill whatever account number appears on a label.
• The most damaging schemes stay small and steady, so the charges blend into normal volume for months.
• Strong access controls narrow the openings, and a line-level invoice audit catches what gets through.

Most companies protect bank logins and payment cards carefully yet treat their parcel account number as routine shipping information. That number appears on every invoice, lives in shipping software at every location, and goes out to vendors who bill shipments back to you. Parcel shipping fraud works in the space between how widely that number circulates and how closely anyone checks the charges against it, and each scheme below uses that space in a different way.

What is parcel shipping fraud?

Parcel shipping fraud is any shipment billed to your carrier account, or any movement of your products through a carrier network, that you did not authorize. Most schemes pursue one of two goals: free shipping paid for by your account, or theft of the goods inside your cartons. The table below summarizes the main types and the first signs each one tends to leave.

Common types of parcel shipping fraud

How do criminals get access to your parcel account?

Criminals usually get access to a parcel account by tricking or exploiting the people who already have it. Phishing emails, texts, and calls that impersonate a carrier ask for account numbers, passwords, or copies of invoices, and UPS states that it does not request any of those in an unsolicited message. A single forwarded invoice is enough to start, since every invoice carries your account number.

Access also outlasts the people who need it. Former employees, departed administrators, and vendors from past projects may still hold working logins or know your account numbers, which is why carriers tell account holders to remove users who no longer need access. Third-party billing arrangements add another opening, because every supplier that bills inbound shipments to your account must know the number to do it.

How does account takeover turn into label resale?

Once criminals control a parcel account, the fastest way to profit is to sell shipping labels billed to it. A 2024 federal case in Washington, D.C. shows how far that can go. Conspirators obtained login credentials for one company's UPS account and used it to ship their own products at no cost. They then advertised labels online, each creating thousands of labels on the compromised account, and the company lost more than $900,000 before access was cut off. The group then moved to a second company's account and resumed selling.

Label resale is hard to spot from inside the company being billed, because the buyers are strangers shipping ordinary packages. Each charge looks like a legitimate shipment on your account, and the volume grows as the seller finds more customers.

How do employees misuse company shipping accounts?

Employee misuse of a shipping account ranges from small personal shipments to organized theft. The simplest form is someone with access who ships personal packages or items for a side business, and the risk grows with every location and user that can create labels. A large network of branch or franchise locations makes those shipments especially easy to miss, because each location's activity is a small share of your total volume.

The more serious form uses your shipping process to move your own inventory. In an indictment reported in 2026, federal prosecutors alleged that warehouse employees at a Nike distribution center in Memphis placed unauthorized UPS labels on selected shoe cartons, sending at least $2 million in product to outside addresses for resale between July 2021 and June 2024. Those labels were billed to outside accounts, so the loss appeared in inventory counts, where shipping invoices would never reveal it. Cases like this show how parcel shipping fraud can damage your supply chain as well as your shipping costs.

What is slow-build parcel fraud?

Slow-build parcel fraud adds packages to a compromised account gradually, so no single invoice shows a jump. Fraudsters have learned that a sudden increase in volume draws attention, so they keep each week's activity small and let it grow over time.

One version we have tracked bills packages to an account with manifested cities that do not match the cities where the packages enter the carrier network. Because those shipments do not line up with the account holder's own manifest data, they tend to arrive on invoices as Missing PLD (Package Level Detail) or Not Previously Billed charges. Across three accounts, this pattern added more than $400,000 in charges before anyone traced it.

Why are counterfeit shipping labels a risk for your business?

Counterfeit and deeply discounted labels are the retail end of parcel fraud. Some come from unauthorized label systems, and some are generated on stolen accounts like the one in the Washington, D.C. case. FedEx warns that unusual shipping prices can be a sign of counterfeit labels and that it may remove suspected shipments from its network, and UPS describes the same practice.

For your business, the risk is a shipment that never arrives. If anyone on your team, or a vendor shipping on your behalf, buys labels from an unofficial reseller, those packages can be pulled from the network along with the product inside them. Labels should come only from carrier channels or your contracted shipping platforms.

How do you stop parcel shipping fraud?

Stopping parcel shipping fraud starts with treating your carrier account like a payment credential. These controls close the most common openings:

• Limit who holds account numbers and logins, and turn on two-step verification wherever your carrier offers it.
• Review authorized users regularly, and remove former employees, departed administrators, and past vendors.
• Restrict third-party and inbound charges to approved partners. UPS lets account holders deny all inbound charges and then list the parties permitted to bill them.
• Give separate account numbers to locations and partners that ship on your behalf, so unusual activity traces back to its source.

• Report unrecognized charges to your carrier's fraud team as soon as they appear, because carrier terms limit how long you have to dispute them, and request new account numbers if yours are compromised.

Controls reduce the openings, and they cannot catch a scheme already running on a valid account. Catching that takes a line-level audit of every invoice, which also builds the record a refund claim needs.

FAQs

How long can parcel shipping fraud go unnoticed?

Parcel shipping fraud can go unnoticed for months when it runs on a valid account, because each invoice looks normal on its own. In the Washington, D.C. label resale case, conspirators used one company's account from no later than 2020 until July 2021.

Who pays for fraudulent shipments billed to your account?

The account holder is billed for fraudulent shipments first, and recovering those charges depends on the carrier's dispute rules. Under UPS's 2025 terms, you have 30 days to dispute unauthorized charges, and fraud-related refunds are capped at $10,000 a year across related accounts, with some exceptions, so early detection and clear records decide how much you get back.

How do you report parcel shipping fraud to a carrier?

You report parcel shipping fraud by contacting the carrier's fraud team with the invoice numbers, account numbers, and tracking numbers for the charges you do not recognize. FedEx asks business customers to gather those details before calling its fraud line, and UPS takes fraud reports through your account manager or its fraud contact.
