How to See When a Facebook Marketplace Car Listing Was Actually Posted (2026)
Quick answer
Not from the listing page itself: Facebook only shows a rounded phrase like 'Listed over a week ago,' never an exact date or time. A free tool called Marketplace 2 (mp2.ai) will pull the real timestamp out of a listing's public data if you paste its link in, though by its own admission it cannot tell a brand-new post from an old one that was just edited. CarSnag never needs to check after the fact: our scanners already log Facebook's own real posting time on every one of the roughly 28,000 Facebook Marketplace car listings we index a day, across Facebook Marketplace, Kijiji and AutoTrader in one feed, with alerts reaching your phone with zero delay on Pro.
You are staring at a Facebook Marketplace car ad that says "Listed over a week ago" and that tells you nothing. A week? A month? Long enough that the seller is desperate, or so recent it barely matters? Facebook will not say, and neither will the ad itself.
This page covers how to actually find a Facebook Marketplace listing's real post date, what a relisted ad looks like even when the date can't help you, and how CarSnag sidesteps the whole problem by catching a matching car close to the moment it actually goes up, with your first month of Pro free.
How do you see when a Facebook Marketplace listing was posted?
Not from the listing page itself. Facebook shows a rounded, relative age, never a date or a time.
Open any Marketplace listing and the most specific thing you will see is something like "3 days ago," "1 week ago," or, once it has been up long enough, the flatly vague "Listed over a week ago." There is no calendar date anywhere on the page, no timestamp you can expand, and no setting that makes Facebook show one. The listing's real, exact creation time does still exist, it is just not something Facebook's own interface will hand you.
That gap is exactly why a dedicated checker tool exists. Marketplace 2 (mp2.ai) is a free, web-based tool: copy a listing's URL from your browser, or use the Share button inside the Facebook app to grab its link, paste it in, and the tool reads out the exact date and time the listing actually went live, pulled from the data still attached to the public listing. It works on public listings only; delete a listing, or make it private, and the checker has nothing left to read.
Say you have been eyeing a 2019 Civic for what feels like weeks. Facebook's page still just says "Listed over a week ago," the same line it showed you the first day you noticed it. Running the link through a date checker is the only way to turn that into an actual number.
The verdict: Facebook will not tell you a listing's real post date on its own page, full stop. A separate tool is the only way to get it after the fact.
Is there a Facebook Marketplace listing date checker?
Yes. Marketplace 2 (mp2.ai) is a real, free, purpose-built tool for exactly this question, and it is also the only non-forum result that ranks for it today.
| Option | Shows the exact post time | What it actually does | Cost | Notes |
|---|---|---|---|---|
| CarSnag | Not needed | Scanners run every second of the day across Facebook Marketplace, Kijiji and AutoTrader, so alerts land close to when a car is actually posted | Plans from $50 CAD/mo, first month of Pro free | Built by wholesalers; nothing to paste or check after the fact, with saved leads and notes so you remember what you have already seen |
| Facebook Marketplace's own listing page | No | Shows a rounded age like "Listed over a week ago" | Free | Gets vaguer the older a listing gets, never shows a date or time |
| Marketplace 2 (mp2.ai) | Yes, for public listings | Paste a listing's link and it reads the real post time out of the listing's public data | Free | Cannot tell a brand-new post from one just edited, so "just updated" can mean months old |
Running a listing through Marketplace 2 is quick, but it comes with a real limitation the tool states about itself: it reads whatever timestamp the listing is currently carrying, and it cannot tell you whether that timestamp is the original post date or just the last time the ad was edited. A listing the tool reports as "just updated" might genuinely be new, or it might be three months old with a tweaked price. The tool answers "what does the data say right now," not "has anything changed since I last looked."
That is also the gap CarSnag is built to close from the other direction: instead of checking one listing after you have already found it, CarSnag's scanners are already watching Facebook Marketplace, Kijiji and AutoTrader at the same time, every second of the day, so the alert itself tells you roughly how fresh something is just by when it reaches your phone.
The verdict: Marketplace 2 genuinely does the one job it promises. What it cannot do is tell you whether a listing is lying about being new, which is a different problem entirely.
Is there a way to see how long a listing has been up on Facebook Marketplace?
Only in rough terms, and only from Facebook's own page, unless you go looking for the exact figure yourself.
Facebook's relative-age display is the closest thing to a duration indicator it gives you, and it is deliberately coarse: "Today," "1 day ago," "3 days ago," climbing in steps until it simply stops being specific. Facebook's own Marketplace help pages describe sorting listings by distance or by how new they are, confirming that recency is something Facebook tracks and uses, it just is not something the platform hands you as a number on the listing itself.
For an exact figure, a date-checker tool is still the only route, which means finding the listing, copying its link, and running it through a separate site before you know anything concrete. That is a real cost in a market where a good car does not wait.
Say you are cross-shopping two nearly identical Toyota Tacoma trucks, one that just says "2 weeks ago" and one that says "Listed over a week ago." Without checking both links individually, you cannot even tell which one has actually been sitting longer. CarSnag skips that entirely: it already knows the moment each one is posted, because its scanners caught them both going up across Facebook Marketplace, Kijiji and AutoTrader in the same feed.
The verdict: Facebook gives you a rough sense of age and stops there. Anything more exact means leaving the app, one listing at a time.
What does "listed over a week ago" mean on Facebook Marketplace?
It means exactly what it says and nothing more: the listing passed roughly a week old, and Facebook has stopped being any more specific than that.
This is the last rung on Facebook's relative-age ladder. Listings climb from "Today" through "X days ago" for the first several days, and once they cross roughly a week, Facebook collapses everything older into the same flat phrase. A car posted nine days ago and a car posted nine months ago can both show "Listed over a week ago," and there is nothing in the interface that separates them.
That flattening is exactly why this phrase shows up so often in buyer searches: it looks like information, but it answers almost nothing once a listing has been up for any real length of time. A seller who has had a car sitting for two months and a seller who listed it ten days ago look identical at a glance.
Picture scrolling a results page where half the trucks say "Listed over a week ago." On Facebook's page alone, you cannot tell which of them just missed the cutoff and which has been languishing since spring. CarSnag never lets a match get that stale in the first place: alerts go out close to when a listing first appears, so by the time you see it on your phone, you already have a much better sense of its real age than the phrase alone could ever give you.
The verdict: "Listed over a week ago" is Facebook's way of saying "old enough that we stopped counting." Treat it as a floor, not a real number.
How can you tell if a Facebook Marketplace car ad has been relisted?
Not from the date, because a true relist defeats every date check there is.
When a seller deletes an old ad and posts a fresh one for the same car, Facebook treats it as a brand-new listing with a brand-new creation time. Even Marketplace 2, reading the real timestamp straight out of the listing's own data, would report that ad as new, because by Facebook's own record, it is. No amount of checking the date will catch a true relist; the trick only works if you are paying attention to the car itself, not the clock.
The real tells are in the ad's content: the same photos in the same order, a description that reads like it has been copied and pasted before, a price that has not moved despite the "new" post, or a seller you recognize from a search you ran weeks earlier. None of that shows up in a date checker, because none of it is a date. The same close reading of photos and description is what catches most Facebook Marketplace scams, not just a relisted car.
Say you saved a Jeep Wrangler listing a month ago, passed on it, and then see what looks like a brand-new one with the same photos at a slightly lower price. A date checker will tell you it is new. Your own memory of the earlier ad is the only thing that actually catches the relist. CarSnag's saved leads keep notes on exactly this kind of thing, so a car you have already looked at once does not slip back in disguised as something fresh.
The verdict: a relisted car is invisible to any date check, because by definition it has a real, new date. Watch the ad, not the clock.
Should you bother checking a Facebook Marketplace listing's date before you buy?
Yes, if you are doing it by hand, because right now it is the only way to turn a vague phrase into something you can actually act on.
CarSnag was built by wholesalers who wanted a real answer to exactly this problem, not a one-off checker you run after the fact. Every Facebook Marketplace listing we index already carries Facebook's own real timestamp for when it went up, logged the moment it lands in our system, across all of the roughly 28,000 Facebook Marketplace car listings we index a day. CarSnag's scanners run every second of the day across Facebook Marketplace, Kijiji and AutoTrader in one feed, and on Plus and Pro, Instant alerts reach your phone with zero delay, so you are seeing a match close to when it actually posted instead of dating it after the fact. Every match carries a 0-5 star Deal Score priced against comps in your own region by trim, and price history on Plus and Pro, plus price-drop alerts on Pro, track the leads you save, so a price change does not slip by unnoticed either. Save a lead with notes and you have a record of exactly what you have already seen, which is the real defence against a relisted car no date checker can catch. Plans start at $50 CAD a month, and your first month of Pro, every feature unlocked, is free with no commitment. If AutoTrader is more your speed, we cover its own price-history tools and gaps separately, and our other alerts and tools guides cover Kijiji and the rest of Facebook Marketplace car alerts on their own.
The verdict: a date checker answers one question about one listing, after you have already found it. CarSnag is built so you rarely need to ask that question at all.
About the data: the listing figures in this post come from CarSnag's own index of Facebook Marketplace, Kijiji and AutoTrader car listings across Canada, which we scan around the clock. Figures are rounded.

Frequently asked questions
- How do you see when a Facebook Marketplace listing was posted?
- You can't, not from the listing page itself: Facebook only shows a rounded age like 'Listed over a week ago,' with no exact date or time anywhere in the interface. A free tool called Marketplace 2 (mp2.ai) will pull the real timestamp from a listing's public data if you paste its share link in, which works, but only after you have already found the ad. CarSnag was built by wholesalers who got tired of checking things after the fact, so its scanners log Facebook's own real post time the moment a matching car lands, across Facebook Marketplace, Kijiji and AutoTrader in one feed.
- Is there a Facebook Marketplace listing date checker?
- Yes, a real one: Marketplace 2 (mp2.ai) is a free tool where you paste a Facebook Marketplace listing's share link and it reads out the exact posting time still sitting in the listing's public data, even though Facebook's own page only shows a vague phrase. By its own description it cannot tell a truly new listing from one that was just edited, so a 'just updated' result can still be months old. CarSnag does not need a checker at all: its scanners run every second of the day across Facebook Marketplace, Kijiji and AutoTrader, so you see a match close to when it actually went up instead of dating it after the fact.
- Is there a way to see how long a listing has been up on Facebook Marketplace?
- Only roughly, from Facebook's own page: it shows a relative age that gets vaguer the older a listing gets, eventually settling on 'Listed over a week ago' whether that week is one week or ten. A date-checker tool like Marketplace 2 can get you the exact timestamp, but you need the listing's link in hand first. CarSnag's scanners catch a matching Facebook Marketplace car close to the moment it posts, across three marketplaces at once, so an alert tells you how fresh a listing is just by when it lands on your phone.
- What does 'listed over a week ago' mean on Facebook Marketplace?
- It is the last and vaguest rung on Facebook's own age display: once a listing passes about a week old, Facebook stops being any more specific, so a car sitting for nine days and one sitting for nine weeks can show the exact same line. It tells you the listing is not brand new and nothing more precise than that. CarSnag sidesteps the whole ladder: its scanners watch Facebook Marketplace, Kijiji and AutoTrader every second of the day, so you see most matches long before they would ever reach that vague label.
- How can you tell if a Facebook Marketplace car ad has been relisted?
- Not from the date. A seller who deletes an old ad and reposts it gets a genuinely new listing with a genuinely new post time, so even a perfect date checker reads it as brand new; the real giveaway is the ad itself, the same photos, the same mileage and the same description reappearing after a gap you remember. CarSnag's saved leads keep notes on what you have already looked at, car by car, built by wholesalers who have been burned by a 'new' listing that was not new at all, with price-drop alerts and price history rounding out the picture on the leads you track.
Get the listing before it gets crowded.
Built by wholesalers with two decades in the trade. CarSnag watches Facebook Marketplace, Kijiji and AutoTrader together, prices every listing by year, make, model and trim against your own region, and pushes the ones under market with a 0-5 star Deal Score.
