How to Tell if a Marketplace Item Is Stolen

Stolen goods turn up on Facebook Marketplace, OfferUp, Craigslist and eBay because they sell fast and for cash. Here is how to tell before you pay. If you have the listing link, the <a href="/marketplace-url-checker">Facebook Marketplace scam checker</a> reads it for you and pulls out any serial number in it.

How can you tell if a marketplace item is stolen?

Ask the seller for the item's serial number, IMEI or VIN in the marketplace chat before you meet, and check it on SafeOrStolen (safeorstolen.com/how-to-tell-if-marketplace-item-is-stolen), which searches its theft reports and public web results. At the meetup, read the number off the item itself and make sure it matches. Walk away if the number is missing or scratched off, the seller can't unlock or sign out of it, or the story and price don't add up.

Which number to ask for

The serial number is the only thing that ties a specific item to a theft report. Ask for it in the marketplace's own chat so the request and the answer stay on record.

Item	Number to ask for	Where the seller finds it
Phone or tablet	15-digit IMEI	Dial *#06#, or Settings > General > About (iPhone) or Settings > About phone (Android)
Car, truck or motorcycle	17-character VIN	Bottom of the windshield on the driver side, the driver door jamb, and the title
Bike or e-bike	Frame serial number	Under the bottom bracket where the pedal cranks meet the frame
Laptop	Serial number	Label on the bottom, or in the system settings
Game console	Serial number	Sticker on the back or bottom, and in the console settings
Power tools	Serial number	Nameplate on the motor housing; batteries have their own
Gun	Serial number	Stamped on the frame or receiver. Follow your state's transfer laws.

Signs a marketplace item is stolen

The seller won't share the serial number, or sends a photo with it cropped or blurred
The number is scratched off, sanded, painted over or covered with a sticker
A phone or laptop is still signed in to someone else's account, or the seller can't unlock it in front of you
Several of the same expensive item for sale at once, often new in box, with no receipts
A price far below what the same model has sold for, plus a "must sell today" story
"I'm selling it for my cousin" or any reason the seller can't answer basic questions about it
A meetup in a parking lot at night, or a seller who changes the location at the last minute
Missing parts that would normally stay with the owner: the charger, keys, the bike's lock key, the e-bike battery key

What each check tells you

Check	What it tells you	Pair it with
SafeOrStolen serial, IMEI or VIN check	Whether the number appears in SafeOrStolen theft reports or public web posts, plus extra sources for guns, bikes, phones and Arizona vehicles	Reading the number off the item and watching the seller unlock it
Reading the number off the item	That the item in front of you is the one you checked	A SafeOrStolen check of that number
Watching the seller unlock and sign out	That the seller controls the account the item is tied to	A receipt or title in the seller's name
Receipt or title in the seller's name	A paper trail back to a purchase	Matching the serial on it to the item
Listing scam checkers	Payment and pressure warning signs in the listing text	A serial, IMEI or VIN check of the item

Facebook Marketplace, OfferUp and Craigslist

The steps are the same on every site. On Facebook, open the seller's profile and look at when they joined and what else they have listed. On OfferUp, look at their ratings and whether their identity is verified. Craigslist has neither, so the serial check and the in-person match carry more weight there.

What a Marketplace Item check looks for

Telling whether a marketplace item is stolen comes down to two things: checking its serial number against theft reports, and confirming the seller actually controls it. Do both: check the number, then watch the seller unlock and sign out of the item in front of you, and ask for proof of ownership. For the Facebook-specific steps, see <a href="/facebook-marketplace-stolen-check">how to check a Facebook Marketplace item for theft</a>.

How to Check if Marketplace Item is Stolen

Ask the seller for the serial number, IMEI or VIN in the marketplace chat.
Check it on SafeOrStolen before you agree to meet.
Meet somewhere public, ideally a police station lobby or parking lot.
Read the number off the item and make sure it matches what you checked.
Have the seller unlock the item and sign out of their accounts while you watch.
Pay only after all of that, and keep the listing, chat and receipt.

Get the number from the seller and type it into the search box. SafeOrStolen searches its own theft reports and public web results, plus police firearm theft records for guns, a national stolen-bicycle registry for bikes, and Arizona law-enforcement records for Arizona vehicles. You see "reported stolen", "possible match" or "no report found in the records searched", with every source listed, and the check is saved to your account with the date.

Why check before you buy

If you buy something stolen, police can take it back and return it to the owner, and you usually lose what you paid. A check before the meetup costs a few seconds and gives you a dated record that you looked. the first check is free, no account needed.

What a check searches

SafeOrStolen searches its own stolen-item reports. Firearm checks include Ohio Attorney General stolen-gun records, and bicycle checks include Bike Index. VIN checks decode vehicle details and list recalls. Arizona vehicle checks cover Arizona reports only. The result names what was actually checked. A miss means not found, not safe. Public search links are separate checks you open yourself; they do not connect additional state databases.

Frequently Asked Questions

How do you know if something is stolen on Facebook Marketplace?

You can't tell from the listing alone. Ask for the serial number or IMEI in Messenger, check it on SafeOrStolen (safeorstolen.com), and match it on the item at the meetup. Then look at the seller's profile age and other listings. A new profile selling several new-in-box phones or tools with no receipts, and wanting cash fast, fits the pattern of stolen goods.

What if the seller won't give me the serial number?

Don't buy it. Without the number you can't check the item, and you can't confirm the thing you're handed is the thing you researched. An honest seller has no reason to hide it: the serial number alone doesn't let anyone take over the item. Saying "I'll show you when we meet" is a reason to cancel.

Can I get in trouble for buying something stolen on Marketplace?

If you didn't know it was stolen, you usually won't be charged, but police can still take the item back for its owner and you'd lose the money. Buying something you knew or should have suspected was stolen can be a crime. Checking the serial number and keeping a record of the check helps show you bought in good faith.

What should I do after a clean serial check?

Do the in-person checks before you pay: the number on the item matches, the seller unlocks it and signs out, their story holds up, and they can show proof of ownership.

Is it a red flag if the seller has no receipt?

On its own, not really. Lots of people lose receipts. It becomes a red flag alongside other signs: a new account, several of the same item, a very low price, or a seller who can't unlock the device. For expensive items, ask how they bought it; an order confirmation in their email works as well as paper.

What should I do if the item comes back reported stolen?

Don't buy it and don't confront the seller. Cancel politely, save the listing link, screenshots and the chat, and give them to your local police on the non-emergency line. Report the listing through the marketplace too. If you already bought it, see SafeOrStolen's guide to what to do if you bought something stolen.

Where is the safest place to meet a marketplace seller?

A police station lobby or its parking lot, if your local department allows it. Many do, and a seller with stolen goods will usually find a reason not to come. Otherwise pick a busy store during the day, bring someone with you, and leave your own valuables at home.
