A troubling new phishing scam has emerged that targets unsuspecting victims with USPS alerts about “incomplete address information” that prevents package delivery. This expansive guide will uncover everything you need to know about how this scam works, common tricks to watch for, and how to keep yourself protected.
Overview of the Scam
This scam begins when a target receives an email, text message, or phone call pretending to originate from the United States Postal Service. The message claims that a package addressed to you has arrived at a warehouse, but cannot be delivered due to missing or incorrect address information.
You are urged to click on a link or call the provided number immediately to confirm your personal details so USPS can update their records and deliver your awaiting package. However, the link and number actually connect to a sophisticated fake USPS website and call center operated by scammers to steal your entered information.
Once scammers have your name, address, date of birth, social security number or other data, they use it to commit financial fraud in your name, steal your identity, or sell the information on the black market. This scam has already resulted in many reported cases of funds being stolen, accounts compromised, and severe identity theft issues.
How the Scam Works
This scam strategically manipulates victims through highly deceptive tactics. Here is an outline of how scammers carry out each stage of this scam:
Crafting Fraudulent Messages
The first step scammers take is creating fake USPS alerts informing recipients about an “incomplete address” issue preventing delivery. These messages closely impersonate real USPS communications related to seized items, unverified addresses, missing unit numbers, and other address problems.
The messages feature USPS branding and language. Email subjects state things like “Update Your Address,” “Incomplete Shipping Address,” or “Important Delivery Error.” Calls play a prerecorded voice citing the same address issue.
Including Fake Tracking Numbers
Some fraudulent messages include a fake but realistic-looking USPS tracking number that victims can enter on the USPS website, where it will appear as a real package in transit.
Seeing the tracking number generate results falsely convinces victims the alert is legitimate and they can trust clicking the provided link for resolution. However, the tracking numbers do not represent actual shipments.
Providing Urgent Call-to-Action
All fake notifications inform recipients they must click on a link or call a provided number urgently to confirm their personal details so their stuck package can be released for delivery.
The messages emphasize acting immediately, as delays could result in returned shipments, fines, or legal consequences. This pressures victims to comply without contemplating the validity.
Directing Victims to Fake USPS Sites and Numbers
The fraudulent messages provide clickable links and phone numbers that at first glance appear to route to the real USPS. However, the link goes to a fake copycat USPS website and the phone number connects to a scam USPS call center.
Both the fraudulent site and call center closely imitate the look, language, and experience of legitimate USPS interactions. But they are controlled by scammers to harvest personal information instead.
Collecting and Stealing Personal Details
Once directed to the phony USPS site or call center, victims are prompted to enter various personal details to “confirm their address.” Information collected includes full name, home address, date of birth, social security number, driver’s license details, phone number, and more.
Providing any of this data gives scammers the ability to steal identities, open illicit credit lines, access existing accounts, file false tax returns, and sell the details on the black market.
Spreading Malware and Spyware
In addition to harvesting directly entered data, some fake USPS sites also contain embedded malware that gets installed on a victim’s device if clicked.
This allows scammers to monitor activities on the device, record keystrokes to steal passwords, access files and cameras, take screenshots, and infect additional connected devices on the network.
Exploiting Stolen Identities
With the sensitive details acquired, scammers then engage in identity theft and financial fraud in victims’ names:
Opening fraudulent credit cards and bank accounts
Filing phony tax returns to collect refunds
Accruing charges on existing accounts
Taking out payday loans and maxing out credit lines
Stealing retirement account funds
Victims can face devastated credit scores, drained bank balances, and a painful mess to prove their innocence as scammers wreck their identity.
Pursuing Secondary Scams and Fraud
Once scammed once, victims get added to “sucker lists” used by scammers to target individuals likely to fall for additional scams. Some examples include:
Calls pretending to be USPS security asking for money or details to help stop ongoing identity theft that doesn’t actually exist.
Scammers impersonate bank or credit card fraud investigation agents asking victims to verify transactions or move funds to safe accounts, allowing them to steal it.
Offers to fully restore victims’ stolen identities or reimburse stolen funds for an advanced fee they pocket without rendering services.
These secondary scams lead to even more stolen money and traumatic stress for victims already dealing with the aftermath of initial fraud.
What to Do If You’re a Victim
If you entered any personal information, contact numbers, or account details into a deceptive USPS site or call center, take these steps immediately:
Contact banks and card issuers to halt charges on accounts while monitoring for any suspicious transactions.
Place 90-day fraud alerts on all credit files to make opening new fraudulent lines of credit harder.
Change account passwords, and security questions, and enable two-factor authentication everywhere possible.
File reports about the scam with the real USPS through their postal inspector website and with the FTC to aid investigations.
Ignore any supposed offers of help recovering lost money or fixing your credit in exchange for payment – this always indicates more scams. Only work directly with real institutions on identity and credit restoration.
If you suspect your device is infected with malware, you should run a scan with Malwarebytes Anti-Malware.
How to Spot This Scam
Though this scam can appear quite convincing on the surface, you can detect it through these warning signs:
Urgent pleas regarding potential legal action or fines if you do not act quickly. Real USPS rarely resorts to these scare tactics.
Requests to re-enter or “confirm” personal information USPS would never contact you for.
Fake USPS sites that upon close inspection have subtle differences from the real USPS site, like incorrect logos, different formatting, misspelled words, etc.
Scam sites lacking HTTPS protocol and without padlock security icons in the URL field.
Emails/calls linking to mismatched domains outside of the official usps.com addresses.
Follow-up contacts from supposed USPS agents requesting additional payments or details to help you.
How to Avoid This Scam
You can protect yourself from the “USPS Incomplete Address” scam using these key precautions:
Never provide sensitive personal or financial data over unverified calls, emails, text messages, or websites.
Independently confirm with USPS via official contact channels if any packages actually await you prior to taking action.
Analyze all links closely before clicking by hovering over them first to preview destinations.
Ensure sites have “HTTPS” protocol, valid security certificates, and request login before asking for info.
Update antivirus software and firewalls to detect and block fraudulent sites trying to spread malware.
Sign up for USPS scam email alerts to stay on top of the latest phishing techniques targeting customers.
Never pay any money or fees to someone claiming they can recover stolen funds or restore your credit or identity.

For additional information regarding the fake USPS “Incomplete Address” scam, read through these FAQs:
How are scammers able to spoof USPS phone numbers on caller IDs?
Scammers leverage technical tricks to manipulate caller IDs to display numbers that appear to match legitimate USPS customer service lines, even when they do not actually originate from those locations. Always find official numbers yourself rather than calling back missed calls alone.
What techniques do scammers use in phone calls?
Calls will feature prerecorded voices or messages urgently citing the need to confirm your address. Scammers leverage authority and intimidation over the phone to try to coerce you into complying. Repeated calls from separate numbers may happen if you do not initially engage.
What is a telltale sign of a scam website?
Fake sites almost always request personal details upfront before allowing account access. On real sites, you can login to your private account first before entering any info. Phishing sites skip this crucial identity verification step.
Can malware infect Macs or mobile devices too?
Yes, malicious scripts can infect any device or operating system if directed to fraudulent sites harboring malware, not just Windows PCs. Always be vigilant when clicking URLs and keep all your software patched and antivirus programs updated.
If my data was stolen, how long until it is used for fraud?
Stolen information can be sold on black markets immediately but may also be kept for months or even years before use. Scammers let time pass for victims to lower their guard before deploying the details. You need to monitor closely across all accounts consistently once scammed.
Are these scammers typically located overseas?
Yes, most of these sorts of phishing operations and scam call centers originate overseas, often from regions in Africa, Asia, and Eastern Europe. They can use proxy tools to mask their real locations and identities. This makes the scammers harder to trace and prosecute.
In Conclusion
This USPS scam leverages familiarity with legitimate package tracking and address verification processes to lower defenses and trick customers into providing valuable personal data. However, being informed on the common tricks and tactics these scammers use makes it much simpler to detect fraudulent USPS communications. Scrutinize notifications thoroughly, and never provide information without verifying legitimacy first through independent contact. Practicing caution protects you from having your identity and finances stolen through this scam.
10 Rules to Avoid Online Scams
Here are 10 practical safety rules to help you avoid malware, online shopping scams, crypto scams, and other online fraud. Each tip includes a quick “if you already got hit” action.
Stop and verify before you click, log in, download, or pay.
Most scams win by creating urgency. Verify using a trusted method: type the website address yourself, use the official app, or call a known number (not the one in the message).
If you already clicked: close the page, do not enter passwords, and run a malware scan.
Keep your operating system, browser, and apps updated.
Updates patch security holes used by malware and malicious ads. Turn on automatic updates where possible.
If you saw a scary “update now” pop-up: close it and update only through your device settings or the official app store.
Use layered protection: antivirus plus an ad blocker.
Antivirus helps block malware. An ad blocker reduces scam redirects, phishing pages, and malvertising.
If your browser is acting weird: remove unknown extensions, reset the browser, then run a full scan.
Install apps, software, and extensions only from official sources.
Avoid cracked software, “keygens,” and random downloads. During installs, choose Custom/Advanced and decline bundled offers you do not recognize.
If you already installed something suspicious: uninstall it, restart, and scan again.
Treat links and attachments as untrusted by default.
Phishing often impersonates delivery services, banks, and popular brands. If it is unexpected, do not open attachments or log in through the message.
If you entered credentials: change the password immediately and enable 2FA.
Shop safely: research the store, then pay with protection.
Be cautious with brand-new stores, “closing sale” stories, and prices that make no sense. Prefer credit cards or PayPal for dispute options. Avoid wire transfers, gift cards, and crypto payments.
If you already paid: contact your card issuer or PayPal quickly to dispute the transaction.
Crypto rule: never pay a “fee” to withdraw or recover money.
Common patterns include fake profits, then “tax,” “gas,” or “verification” fees. Another is a “recovery agent” who demands upfront crypto.
If you already sent crypto: stop paying, save evidence (wallet addresses, TXIDs, chats), and report the scam to the platform used.
Secure your accounts with unique passwords and 2FA (start with email).
Use a password manager and unique passwords for every account. Enable 2FA using an authenticator app when possible.
If you suspect an account takeover: change passwords, sign out of all devices, and review recent logins and recovery settings.
Back up important files and keep one backup offline.
Backups protect you from ransomware and device failure. Keep at least one backup on an external drive that is not always connected.
If you suspect infection: do not connect backup drives until the system is clean.
If you think you are a victim: stop losses, document evidence, and escalate fast.
Move quickly. Speed matters for disputes, account recovery, and limiting damage.
Stop payments and contact: do not send more money or respond to the scammer.
Call your bank or card issuer: block transactions, replace the card if needed, and start a dispute or chargeback.
Secure your email first: change the email password, enable 2FA, and remove unfamiliar recovery options.
Secure other accounts: change passwords, enable 2FA, and log out of all sessions.
Scan your device: remove suspicious apps or extensions, then run a full malware scan.
Save evidence: screenshots, emails, order pages, tracking pages, wallet addresses, TXIDs, and chat logs.
Report it: to the payment provider, marketplace, social platform, exchange, or wallet service involved.
These rules are intentionally simple. Most online losses happen when decisions are rushed. Slow down, verify independently, and use payment methods and account controls that give you recourse.
