If you received a physical letter in your mailbox from Eric Rice or Muma referencing an address on Landeros Drive in San Mateo, California, don't follow its instructions. These mailings claim you can claim a free gift card, PayPal refund, or cash reward ($10 to $50) for reviewing an Amazon purchase or scanning an enclosed QR code. It's a review solicitation scam. Scanning the code or sending proof of a review puts your personal data at risk and violates Amazon Terms of Service.
The sender uses order data from third-party Amazon seller channels to mail buyers directly. They offer gift card codes in exchange for positive reviews or feedback photos. Interacting with these letters risks phishing attacks, account suspension on Amazon, and identity harvesting. Here is what's behind the Landeros Drive letters, how the scheme works, and what you should do if one arrives in your mail.
What Is the Eric Rice Muma Landeros Letter?
The mailing arrives as an envelope addressed directly to your home. Inside is a letter signed by "Eric Rice," "Muma," or "Customer After-sale Team." The listed sender address is usually 466 Landeros Drive or 468 Landeros Drive, San Mateo, CA 94403.
The letter references an exact item you recently purchased on Amazon—such as earplugs, electronics, household goods, or sleep products. It thanks you for your purchase and offers an incentive, usually a $10, $25, $40, or $50 Amazon gift card, PayPal cash, or free product gift.
To claim the reward, the letter directs you to do one of two things:
- Scan a printed QR code with your smartphone camera.
- Send an email with a screenshot of your positive Amazon product review to an unverified email address (like
flashdrive@ssnotice.com,getfree@ssnotice.com,Bestsleep4u@outlook.com, orBinggift725@outlook.com).
While the paper stock and branding look official, the operation isn't authorized by Amazon. It's an illegal incentivized review scam operated by rogue third-party marketplace sellers.

How Scammers Obtain Your Amazon Purchase Details
Many recipients wonder how a stranger in San Mateo knew their name, shipping address, and exact Amazon order history. Understanding the mechanics clears up privacy concerns.
When you purchase an item on Amazon fulfilled by a third-party seller (Merchant Fulfilled / FBM) or through certain seller dashboard integrations, the third-party seller receives your shipping address and order details to fulfill the package. Bad actors operating these merchant stores export customer list details.
They cross-reference purchase histories, print physical mailers through automated fulfillment services, and send letters to recent buyers weeks after the package arrives. They use physical postal mail instead of Amazon's internal buyer-seller messaging system because Amazon automatically flags and blocks review-solicitation messages containing external links or financial rewards.
Physical mail bypasses digital spam filters, landing directly in your hands.
Risks of Scanning the QR Code or Emailing the Sender
Interacting with the letter creates serious security and account risks.
1. Phishing and Personal Data Harvesting
When you scan the QR code on the letter, it opens a web form hosted on an unverified third-party site. The form asks for your full name, email address, phone number, Amazon Order ID, and PayPal account address. Collecting this information connects your physical home address to your online financial profiles, making you a target for targeted phishing attacks, spam lists, and credential stuffing.
2. Loss of Amazon Review Privileges
Amazon strictly prohibits incentivized reviews under its Customer Review Creation Guidelines. Offering or accepting gift cards, refunds, or discounts in exchange for writing positive reviews violates seller and customer terms.
Amazon tracks sellers using these scam mailers. If Amazon links your customer account to submitted screenshot verification or incentivized reviews, the platform can permanently revoke your ability to post reviews, ask product questions, or participate in Community features.
3. Fake Promises and Zero Payout
Reports filed with consumer protection agencies reveal that the promised gift cards rarely arrive. After targets submit their review verification screenshot, the scammers often demand a 5-star rating adjustment, request additional personal verification, or disappear entirely. In some cases, automated email responses state that your account needs "verification," directing you to phishing links designed to harvest login credentials.
Step-by-Step: What to Do When You Receive the Mailer
If an Eric Rice or Muma letter lands in your mailbox, follow these steps to protect your data and account.
- Do not scan the QR code. Avoid opening any link printed on the physical mailer.
- Do not write or modify an Amazon review for cash. Never exchange reviews for gift cards or payouts.
- Report the seller to Amazon. Log into your account, locate the item in your order history, click "Get Help," and report a violation of buyer communications or incentivized review schemes.
- Report the mailer to federal agencies. File a fraud ticket with the Federal Trade Commission and submit an online mail fraud form to the United States Postal Inspection Service.
- Recycle or shred the letter. Once reported, discard the document safely to protect your physical address details.

Common Questions About the San Mateo Mail Scams
How did the sender get my home address and order details?
The sender is connected to a third-party marketplace store on Amazon where you placed an order. Third-party sellers access shipping address data to fulfill orders and misuse that information off-platform to send paper mailers.
Is Eric Rice Muma a real individual or a business name?
"Eric Rice" and "Muma" act as front names and brand aliases printed on automated bulk mailers. They don't represent an authorized Amazon corporate department. Residential address listings on Landeros Drive in San Mateo are frequently used as return addresses for these high-volume review operations.
Will Amazon ban my buyer account if I receive this letter?
Receiving the letter won't harm your Amazon account. You only risk penalties if you follow the letter's instructions, submit fake reviews, or accept funds in exchange for rating seller products.
What happens if I already scanned the QR code?
If you scanned the code but didn't submit personal details or passwords, close the browser window immediately. If you entered sensitive credentials or banking info, change your passwords right away and monitor your financial statements for unauthorized activity.
