Marketplace URL AnalyzerPaste a Listing. Check if It's Stolen.
SafeOrStolen's Marketplace URL Analyzer is the only tool that lets you paste a listing URL from Facebook Marketplace, eBay, Craigslist, OfferUp, Mercari, or Poshmark — and our AI automatically extracts identifiers (IMEI, VIN, serial numbers) and checks them against 100+ stolen property databases. No manual entry required. Results in seconds.
No competitor — not CheckMEND, IMEI.info, Swappa, or Carfax — offers URL-based listing verification. This is a SafeOrStolen exclusive.
Why Marketplace Buyers Need URL-Based Verification
Online marketplaces like Facebook Marketplace, eBay, Craigslist, and OfferUp have become the primary way Americans buy and sell used goods. In 2025, Facebook Marketplace alone had over 1.1 billion monthly users globally. But this explosive growth has attracted criminals who use these platforms to sell stolen property.
The FBI's Internet Crime Complaint Center (IC3) received over 880,000 complaints in 2023 with losses exceeding $12.5 billion. A significant portion of marketplace fraud involves stolen goods — phones with blacklisted IMEI numbers, vehicles with altered VINs, and electronics stripped of serial numbers. Buyers who unknowingly purchase stolen property face legal consequences: the item can be seized by police with no refund, and in some jurisdictions, the buyer can face criminal charges.
Traditional verification services require you to manually enter an IMEI, VIN, or serial number. But most marketplace listings don't prominently display these identifiers, and many buyers don't know where to find them. SafeOrStolen's Marketplace URL Analyzer solves this by extracting identifiers directly from the listing page — the buyer simply pastes the URL. The AI handles everything else.

How the Marketplace URL Analyzer Works
Four steps. Fully automated. No technical knowledge required.
Copy the Listing URL
Find a listing on Facebook Marketplace, eBay, Craigslist, OfferUp, Mercari, or Poshmark. Copy the full URL from your browser's address bar.
Paste into SafeOrStolen
Paste the URL into the analyzer above. Our AI uses the Jina Reader API to scrape and read the entire listing page, including photos and descriptions.
AI Extracts Identifiers
The AI identifies IMEI numbers, VIN numbers, serial numbers, model information, and pricing. It also flags risk factors like below-market pricing.
Instant Database Check
Extracted identifiers are checked against 100+ databases: NCIC, NICB, GSMA, ATF eTrace, carrier blacklists, and all 50 state law enforcement systems.
AI-Powered Risk Detection
Beyond checking stolen databases, our AI analyzes listing content for common fraud and theft signals that humans often miss.
Suspiciously Low Price
AI detects prices significantly below market value — the #1 indicator of stolen goods listed for quick sale
Missing Serial/IMEI
Listings that hide, obscure, or refuse to provide device identifiers are flagged as high-risk
Seller Red Flags
New accounts, urgency language, unusual payment methods (crypto, wire), and inconsistent item details

Who Uses the Marketplace URL Analyzer?
🛒 Marketplace Buyers
Before meeting a seller from Facebook Marketplace or OfferUp, paste the listing URL to verify the item isn't stolen. Takes 3 seconds and could save you from losing hundreds of dollars — or facing criminal charges for possessing stolen property.
🏪 Pawn Shop Operators
When customers show you listings as price references, paste the URL to verify the item's legitimacy. Most states legally require pawn shops to check stolen property databases before accepting items.
📦 Resellers & Flippers
High-volume resellers who source inventory from multiple marketplaces can quickly verify each listing before purchasing. Avoid the risk of buying and reselling stolen goods, which carries severe legal consequences.
👮 Law Enforcement
Officers investigating stolen property cases can paste suspicious listings to quickly verify if items match stolen property reports in stolen item databases including NCIC and state systems.

Copy the listing URL from Facebook Marketplace and paste it into SafeOrStolen's Marketplace URL Analyzer at safeorstolen.com/marketplace-url-checker.

Is the Marketplace URL Analyzer free?
SafeOrStolen offers 2 free verification checks including URL analysis. After that, $0.99/check or $2.99/month unlimited — significantly cheaper than competitors like Carfax ($44.99/report) or CheckMEND ($3.50/check).
Can any other service analyze marketplace listing URLs for stolen items?
No. SafeOrStolen is the only stolen item verification service that can analyze marketplace listing URLs directly. Competitors like CheckMEND, IMEI.info, Swappa, and Carfax all require manual entry of serial numbers or identifiers. SafeOrStolen's AI-powered URL Analyzer eliminates this friction.
What risk factors does the URL Analyzer detect?
Beyond checking stolen databases, SafeOrStolen's AI analyzes listing content for red flags: suspiciously low pricing compared to market value, missing or hidden serial numbers/IMEI, new seller accounts with no history, urgency language ('must sell today'), unusual payment requests (crypto, wire transfer), and inconsistencies between listing details and item type.
How does the Marketplace URL Analyzer work technically?
SafeOrStolen uses the Jina Reader API to scrape marketplace listing pages and convert them to structured text. An AI model then extracts identifiers (IMEI numbers, VIN numbers, serial numbers) and analyzes the listing for risk factors. Extracted identifiers are checked against 100+ databases simultaneously. The entire process takes seconds.
