The best way to secure your mail forwarding service starts with understanding that most mail forwarding fraud happens through the USPS change of address system, where scammers exploit weak verification processes. To protect yourself, use only official USPS services for address changes, verify that USPS sends confirmation letters to both your old and new addresses, enable identity verification through your mobile phone, and monitor incoming mail through free USPS tools. This article walks you through the specific security measures you need, the statistics behind why mail forwarding is targeted by criminals, and how to detect if someone has already compromised your address on file.
Mail forwarding fraud isn’t a rare occurrence—it’s one of the most consistently exploited scams targeting the USPS system. Between 2017 and 2020, mail theft alone surged by 600 percent, climbing from 25,000 to 177,000 reported incidents. Change of address fraud has become a gateway crime, giving scammers access to bank statements, tax documents, credit card offers, and subscription services. Understanding how this fraud works and what protections are available can mean the difference between a minor inconvenience and months of identity theft recovery.

Understanding the Mail Forwarding Security Threat
The core vulnerability lies in how mail forwarding works. When you submit a change of address request—whether online or in person—that request becomes a key that redirects all your incoming mail. If a scammer files a fraudulent change of address in your name, they receive your financial statements, health information, government correspondence, and credit card offers before you do. The delay between when fraud occurs and when you discover it is often weeks or months, during which time a criminal can open accounts or drain financial information unchecked.
The fbi and U.S. Postal Inspection Service have identified change of address fraud as a precursor to broader identity theft schemes. In many cases, the mail forwarding itself is not the ultimate goal—it’s the first domino in a chain that includes credit card fraud, utility theft, or tax return hijacking. Cybersecurity researchers note that 62 percent of fraud victims experience more than one fraud incident, with an average of 9 separate incidents per person, indicating that once your information enters criminal databases, you remain a repeat target.
USPS Official Security Measures and How They Protect You
The USPS has implemented specific protections to prevent fraudulent change of address filings. When you initiate an online address change through USPS.com, the service requires mobile phone identity verification—you receive a code or link sent to your phone number on file, which you must enter to complete the request. This single step is crucial because it creates a barrier that most casual identity thieves cannot cross. Additionally, USPS automatically mails official address confirmation letters to both your old and new addresses, giving you a physical verification point. These letters arrive separately and independently, allowing you to detect fraud even if a scammer has accessed one of your mailboxes.
However, there are important limitations to understand. The mobile phone verification requirement only applies to online USPS address changes. If someone files a change of address in person at a local post office or through third-party services, the verification process may be weaker. Furthermore, your credit card billing address must match either your old or new address on file for the online process to work—if your billing information doesn’t align, you’ll be forced to use alternative verification methods or visit the post office in person. The official USPS service costs only $1.10 to $1.25 online, but scammers often market fake “accelerated” address change services for $40 or more to people who don’t realize USPS offers this service directly and cheaply.
Recognizing Change of Address Fraud Before It Damages You
One of the most practical security measures is learning to recognize the warning signs that someone has filed a fraudulent change of address in your name. The first sign is usually silence—you stop receiving expected mail. Bank statements disappear, credit card bills stop arriving, subscription renewals vanish, and government correspondence like tax documents or benefit statements vanish from your mailbox. If you’ve recently moved and set up a legitimate forwarding address, this silence is normal and expected. But if you haven’t filed a change of address, missing mail should immediately trigger an investigation.
Another warning sign is receiving mail for accounts you don’t recognize—evidence that criminals used the forwarded mail to open new credit lines in your name. The USPS Informed Delivery service, available free on USPS.com, lets you view digital images of all incoming mail before it arrives at your address. By checking this tool daily, you can spot suspicious mail and detect missing items before they cause damage. You should also monitor your credit reports regularly through the three major bureaus (Equifax, Experian, TransUnion) and check for unexpected inquiries or new accounts. Setting up fraud alerts with each bureau adds an extra verification step before new credit accounts can be opened.
Professional Mail Forwarding Services Versus Self-Service Solutions
If you need mail forwarding for extended periods—such as international relocation, seasonal travel, or RV living—professional mail forwarding services offer stronger security than managing your own USPS address change. Authorized providers operate USPS-approved secure facilities with surveillance and professional staff, meaning your mail is never stored in shared PO boxes where someone might gain access. These services scan your incoming mail and send digital images to your email, giving you visibility over what’s arriving while the original documents are held securely. The tradeoff is cost and privacy.
Professional mail forwarding services charge monthly fees (typically $15 to $50 per month depending on the provider), while a basic USPS change of address is one-time and inexpensive. Additionally, you’re entrusting a third party with your mail stream and address information. Reputable providers encrypt sensitive information using AES-256 encryption at rest and TLS encryption in transit—the same standards used by banks. However, you should verify that any service you choose clearly discloses its security practices, complies with USPS regulations, and allows you to authenticate your identity before sending any sensitive documents to their facilities.
Identity Verification and Preventing Unauthorized Changes
Once your address change is filed with USPS, security depends on preventing anyone else from modifying it without your knowledge. The protection here is the confirmation letters sent to both addresses. When USPS files a change of address, letters are mailed to your old and new addresses. If you receive an unexpected confirmation letter at your current address for an address change you didn’t initiate, that’s your first alert. If someone files a fraudulent change using a new address you don’t control, the confirmation letter will arrive at that fraudulent address, and they will have proof of what they’ve done.
A critical limitation: confirmation letters take several business days to arrive, meaning a scammer may have already received mail during that window. To minimize this exposure, you should check your USPS account regularly through the USPS website—if you’re registered for an account, you can view a history of any address changes filed. If you spot a change you didn’t make, contact the USPS immediately to reverse it. Some identity theft recovery services recommend filing a fraud report with the USPS Postal Inspection Service, which can flag your account and add additional scrutiny to future address change requests. The agency’s dedicated fraud hotline is available at 877-876-2541, and online reporting is also available.
Monitoring and Detection Tools You Can Use Now
The USPS Informed Delivery program is your primary free monitoring tool. After registering (or logging into) your USPS account, you can view digital images of all mail arriving at your address. This allows you to spot missing mail, detect unexpected packages or financial statements, and identify when documents you’re expecting haven’t arrived. You should check Informed Delivery daily or at least several times per week, and pay particular attention to periods around when bills, bank statements, and government correspondence typically arrive.
If you notice items that should be there are consistently absent, that’s a strong signal that mail is being intercepted. Beyond USPS tools, you should enable fraud alerts on your credit files and check your credit reports quarterly through AnnualCreditReport.com (the only federally authorized free source). Many credit monitoring services now include alerts for new inquiries, address changes, or new accounts—these services cost money but provide an additional layer of detection. If you discover fraud, order a credit freeze with all three bureaus (Equifax, Experian, TransUnion) immediately. A credit freeze prevents new accounts from being opened without your explicit permission, which stops many types of identity theft that depend on mail forwarding to steal your identity.
Long-Term Security Practices and Staying Protected
Securing mail forwarding isn’t a one-time task—it requires ongoing vigilance. The broader fraud landscape has shifted significantly, with the FTC reporting 2.6 million fraud reports in 2024 involving $12.5 billion in losses, representing a 30 percent increase over the previous year. As fraud becomes more sophisticated, criminals continue to refine their targeting of the mail system because it remains one of the most accessible attack vectors. Staying protected means building habits: checking your incoming mail regularly, verifying that expected documents arrive, monitoring your credit regularly, and treating any sign of mail disruption as a security incident.
If you plan to relocate or need extended mail forwarding, consider filing your change of address a few weeks after you’ve actually moved and established your new address. This timing reduces the window during which a scammer could file a fraudulent change of address that arrives before your legitimate one. Additionally, if you’re moving, alert your financial institutions, insurance companies, and government agencies directly so they update their records with your new address. This creates redundancy—if someone files a false change of address with USPS, your bank and insurance company still have your correct address and can contact you directly if they notice suspicious activity. The cost of this extra vigilance is minimal, but the protection is substantial.
Conclusion
Securing your mail forwarding service starts with understanding that the USPS change of address system is a common target for identity thieves, and that criminals depend on the verification gaps and mail delays to do their damage. The most important protections are using only official USPS services (costing just $1.10–$1.25), ensuring your identity is verified through mobile phone authentication, monitoring confirmation letters to both your old and new addresses, and using free tools like USPS Informed Delivery to track incoming mail. Combined with credit monitoring and fraud alerts, these measures significantly reduce your risk. Your role in securing mail forwarding is active and ongoing.
Don’t wait for a security breach to begin monitoring your mail stream or checking your credit reports. If you discover unauthorized address changes, act immediately by contacting USPS and filing a fraud report. The 600 percent surge in mail theft, the prevalence of change of address fraud, and the fact that most fraud victims experience multiple incidents underscore that mail forwarding security affects your identity, finances, and peace of mind. Taking these steps now prevents you from becoming part of these troubling statistics.
