A tracking number, customs notice, or extra invoice may look official and still be part of a scam. Check the claim somewhere else first. Only then decide whether to click, pay, or share information.

For a U.S. order, sort out the problem before choosing a remedy. It may be a seller delay, a delivery problem, or payment fraud. The FTC mail-order rule can address a seller's shipping promise. A card issuer handles a credit-card billing error. A carrier or customs broker handles delivery-related work. Those processes can overlap, but they are not substitutes.

This is practical information, not legal advice. It is aimed at U.S. consumers. Other countries and marketplace policies may use different rules.

What actually controls the dispute

Begin with the event you can document, not the message's tone. A late parcel isn't automatically fraud, and an unexpected customs charge isn't automatically fake.

The FTC's Business Guide to the Mail, Internet, or Telephone Order Merchandise Rule discusses shipment representations made by sellers. It doesn't decide every carrier loss, customs assessment, or damaged-goods claim.

A tracking page can't settle the payment dispute. Your payment method still controls that step.

Red flags in a shipping message or invoice

Delays can be messy without being fraudulent. The sharper warning signs are pressure, secrecy, and payment requests that don't fit the order.

One sign may have an innocent explanation. Several together deserve a pause.

• An unsolicited text or email says the package will be returned unless you act within hours.
• The message sends you to a lookalike carrier or customs website.
• The tracking number can't be found on the carrier's own site, or the shipment details don't match your order.
• A caller claiming to be customs asks for your Social Security number, card details, gift cards, cryptocurrency, or a wire transfer.
• A seller adds vague port, storage, insurance, or release charges after payment without an itemized explanation.
• The seller changes bank details, refuses written records, or insists on using only a private messaging app.
• A second invoice appears for the same shipment, but no one can identify the carrier, broker, or underlying charge.

The USPS Scheme Alerts page describes smishing as deceptive text messaging intended to obtain personal or financial information. A delivery message needs independent verification, even when it names a real company.

Verify a shipment without clicking the message

Don't let a suspicious message verify itself. Use this sequence instead:

1. Pause. Don't click, call, reply, or pay through the message.
2. Go to the carrier's official site or app yourself. Type the address into your browser or use an app you already trust.
3. Enter the exact tracking number. Compare the carrier, origin, destination, dates, and status with the order.
4. Account for cross-border handoffs. An international parcel can move between carriers and receive a second tracking number. That mismatch alone doesn't prove fraud.
5. Contact the seller through the order page or marketplace. Ask which carrier or broker has the parcel and whether a charge is actually due.
6. Check customs separately. Find the agency, carrier, or broker's contact details on its official website, not in the notice.
7. Save the records. Keep the message, invoice, tracking page, order confirmation, and payment record before anything disappears.

Turns out, a valid tracking number proves only that a number exists in a system. It doesn't prove the right goods were shipped or that delivery happened.

Customs payment demands need extra care

Customs charges can be genuine. Import duty, tax, brokerage, and storage may depend on the goods, destination, delivery terms, and who agreed to act as importer.

An order marked "shipping paid" doesn't answer every import-cost question. Read the order terms and request an itemized explanation before paying.

The FTC's alert about scammers impersonating U.S. Customs and Border Protection says CBP won't call out of the blue with promises of money or threats. It also says CBP doesn't use gift cards, cryptocurrency, or wire transfers.

If someone claims to be CBP, don't use the number in caller ID, a voicemail, or the message. Find the agency's official website yourself and use its published contact details. A carrier or broker can confirm the shipment reference, the reason for a charge, and the proper payment channel.

Thing is, even a genuine fee doesn't require panic.

A missing parcel is not automatically a fraud case

Start with the order record. Keep the seller's shipment promise, the delivery terms, and the date payment was accepted.

For U.S. mail, internet, and telephone orders, the FTC says the 30-day rule applies when the seller made no shipment representation. If the seller stated a shipping time, it must have a reasonable basis for that statement.

That rule addresses the seller's shipment obligation. It doesn't guarantee a customs release or an arrival date set by a foreign carrier.

Write to the seller through a traceable channel. Include the order number, promised shipping date, and current tracking status. Ask for the result you want: a clear update, a replacement, or a refund if the order can't be completed.

The FTC guide describes notice and refund steps for covered orders that can't ship on time. Marketplace deadlines may be separate and shorter, so open the platform's dispute case promptly rather than relying on a vague promise.

A "delivered" scan doesn't end the inquiry. Ask the seller to open a carrier investigation, then check delivery details, building records, household members, and safe-place instructions before alleging fraud.

Your payment method changes the next move

The payment rail determines your next call and the deadline worth watching. Credit-card protections don't automatically transfer to debit cards, wires, or payment apps.

With a U.S. credit card, a charge for goods you never received may qualify as a billing error. The FTC's consumer guidance on billing errors says to dispute it in writing within 60 days of the date the first statement showing the error was sent to you. Use the billing-dispute address supplied by the issuer.

Under the CFPB's Regulation Z billing-error rule, the issuer generally must acknowledge a qualifying dispute within 30 days unless it has already resolved the problem. It must resolve the dispute within two billing cycles, and no more than 90 days, under the rule.

The FTC says you don't have to pay the disputed amount or related finance charges while the issuer investigates. Follow the issuer's instructions for undisputed charges, and keep copies of what you send.

A billing dispute starts a formal review. It doesn't guarantee a refund.

Build a clean record before the trail goes cold

Good evidence is often boring.

To be honest, the useful material is usually the order confirmation, product page, seller's shipping promise, marketplace terms, tracking screenshots, original and later invoices, customs notice, call log, payment record, and damage or packaging photos. Put it all in one place, even if some of it seems repetitive.

Save the full email and its headers when possible. A screenshot shows what appeared on screen, but the original message may reveal the sender, link, or attachment details. Record dates while they're fresh, and keep the original files unedited.

If you entered card or bank information on a suspicious page, call the institution using the number on your card or statement. Ask whether the account should be blocked or replaced. Change any password you reused on the shopping or shipping account.

Report the impersonation, not just the missing parcel

Report the fake identity and the delivery problem separately. Each organization may need different details.

For a suspicious USPS message, follow the reporting guidance on the USPS Scheme Alerts page. That page also points readers toward federal reporting options for scam messages.

For a fake CBP call or customs demand, use the instructions in the FTC alert about CBP impersonation. Stop negotiating with the caller.

Tell the seller, marketplace, carrier, and payment provider what happened. Include the transaction amount, shipment number, dates, and exact payment request. If the seller appears fraudulent, preserve the order page before reporting the account.

Common questions

Is an invalid tracking number proof of fraud?

No. The seller may have entered it incorrectly, or an international handoff may have produced a different number. Concern rises when the number comes with a lookalike site, an urgent payment demand, or a refusal to provide basic shipment details.

Are customs fees always a scam?

No. Duties, taxes, brokerage charges, and storage fees can be legitimate. Verify the charge through a carrier, broker, or government contact you found independently, and request an itemized explanation before paying.

Does a credit-card dispute guarantee a refund?

No. It gives the issuer a process for reviewing a qualifying billing error. The outcome can depend on the records, the type of charge, the merchant's response, and the applicable rules.

Should I wait for the seller before contacting my card issuer?

Don't let a seller's promise make you miss a dispute deadline. Contact the seller in writing, but check the issuer's deadline and instructions as soon as you suspect a qualifying billing error.

Your next five minutes

Before paying another fee, type the carrier's official address yourself, enter the tracking number, and save the suspicious message. If money or account information has already left your control, contact the bank, card issuer, or payment service now using verified contact details.
