Do QR Codes Expire? The Pattern Never Does

Four Different Things People Call an Expired QR Code

"The QR code expired" is a description of a symptom, not of a cause, and the four causes behind it need four different fixes. Three of them are repaired without touching the printed material; one of them is a reprint. Working out which one you are looking at takes a minute and decides everything that follows.

Notice which column the interesting information is in. Two of the four failures are somebody else's decision arriving on your printed material without notice, and neither of them changes anything a customer can see on the object. The code looks exactly as it did the day it was printed, which is what makes the phone call about it so confusing.

The Symbol Has Nowhere to Put an Expiry Date

A QR code encodes characters and nothing else. The standard, ISO/IEC 18004, describes how text is turned into a grid of light and dark modules, how that grid carries error correction, and how a decoder finds and reads it - and it defines no field for a creation date, an expiry date, an account, a licence or an owner. There is nowhere for a shelf life to live.

That is why the answer is the same whichever generator made the code. A static QR code is a code whose destination is stored in the pattern itself, so no server sits between the scan and the page. Any tool that hands you a static file has handed you something with no dependency: the file decodes offline, on an aeroplane, on a phone in a country where the company that made it has never operated.

What people are remembering when they expect an expiry date is a free trial. Several platforms give away dynamic codes on a trial, and a trial does end - but what ends is an account on a service, not a property of the symbol. The distinction matters because it tells you what to check: never the code, always the thing the code points at.

One consequence is worth stating plainly, because it cuts the other way. A static code cannot be switched off, which also means it cannot be recalled. If a printed code points somewhere you would rather it did not, the only remedies are changing what is served at that address or collecting the printed material back in.

A Dynamic Code Expires Because Its Redirect Does

A dynamic QR code is a code that encodes a short link belonging to the provider, which redirects to wherever you currently point it. The pattern therefore contains a hostname you do not own, and that hostname keeps resolving for exactly as long as somebody keeps paying for it. This is the one case where "the QR code expired" is a fair description of what happened.

The vendors document what lapsing does, and the answers differ enough to be worth reading before choosing one. These are statements the vendors published, verified for this site's comparison pages in July and August 2026 - policy pages move, so confirm the current wording before relying on any of them.

• The codes go inactive. Uniqode states that dynamic codes become inactive once a free trial expires or a subscription is cancelled, and that static codes continue to work. The Uniqode comparison has the full picture.
• Some codes survive and some do not. QRCodeChimp pauses scans once the free plan's 1,000 monthly scans are used, and a lapsed paid account keeps only the ten most recent dynamic codes active - so which of your printed codes survives depends on the order they were created in.
• The allowance runs out mid-campaign. Pageloot counts scans per year, 15,000 on Starter through 250,000 on Pro, and QR Planet's free account allows 100 scans a day. A campaign spends an allowance in bursts, so the tier that matters is the one covering the peak week rather than the yearly average.
• The link is deleted rather than expired. Bitly's support documentation states that a deleted link and any QR codes attached to it are removed permanently and cannot be recovered, and that anyone scanning afterwards lands on a Bitly error page.
• Something is inserted in front of your page. ME-QR's free dynamic codes display advertising between the scan and the destination. The code still resolves, which is why this one never shows up in testing - you see your own page, and the customer sees an advertisement first.

The structural version of this is not about any one vendor's reliability. Google retired its own URL shortener: its developers blog stated that goo.gl links "will no longer return a response after August 25th, 2025", a plan later narrowed to links that had shown no activity in late 2024. Anyone who had printed a goo.gl code received an announcement they had no part in and a deadline they could not act on, because the address was in ink. What a dynamic QR code subscription actually buys works through what that costs over the life of a printed object.

If reading this has turned the question from "will my code die" into "which kind should I have printed", that is a different question with a different answer - static or dynamic, decided before anything is printed takes it from the top.

Do Canva, QRCode Monkey or Bitly Codes Expire?

The brand-level version of the question has a brand-independent answer: a code expires if and only if the tool made it dynamic. What varies between vendors is which kind of code you got, and whether you were told which kind it was.

• QRCode Monkey. No. Its codes are static and it says so plainly - they "do not expire and will work forever", with no cap on scans. Whether QRCode Monkey is really free covers what that does and does not include.
• Canva. Its built-in QR code app was static-only for years, and a static code from it has nothing to expire. Canva's help centre now documents dynamic codes with analytics on the business tiers, and a dynamic code depends on the plan behind it - so check in the editor which kind you generated rather than assuming, and see the Canva comparison for what the export gives you.
• Bitly. A bit.ly QR code is a dynamic code by construction: the pattern encodes a bit.ly link. Bitly states that bit.ly links keep resolving if you downgrade or the account is deleted for inactivity, and that a link you delete yourself takes its QR codes with it permanently.
• Any generator that asked you to create an account before downloading. That is the tell worth knowing. An account is where a dynamic code's destination is stored, and a tool that hands over a file without one has nothing to store - though several account-based tools make static codes too, so it is a hint rather than a proof.

The reliable way to settle it for a code you already have is to read the code rather than the marketing. Decode the file and look at the URL inside: if it is your own address, the code is static and permanent; if it is a short link on somebody else's domain, everything about its future belongs to them. The QR code scanner reads a file back and shows you the string.

How Long a Printed QR Code Lasts on the Object

A printed QR code lasts as long as the contrast between its dark and light modules survives, which is a property of the ink, the substrate and the environment rather than of the code. This is the only sense in which a QR code has a lifespan, and it is the one the software vendors never write about, because the failure happens on paper rather than in an account.

Four things end a printed code, and each has a substrate it happens on first:

• Thermal paper fades. Receipts, ticket stubs and label-printer output darken and then bleach with heat, sunlight and time. A code on a receipt is a code with a service life of weeks in a warm car.
• UV chalks outdoor ink. Stickers, window decals and vehicle graphics lose density from the sun, and the dark modules lighten before the substrate does - which narrows contrast from the side that matters.
• Handling abrades the surface. A menu, a loyalty card or a hang tag picks up scratches, and a scratched gloss laminate scatters light across the symbol at the angle a phone is held. Matte vs gloss printing covers which finish survives handling and which one only looks like it will.
• Water and grease change the substrate. Anything on a table absorbs oil, and an absorbed light module is no longer a light module. Lamination fixes this and introduces the glare problem in the same step.

Error correction buys some margin here rather than immunity. Level M recovers roughly 15% of a damaged symbol and level H roughly 30%, which is what lets a scuffed code keep reading - but that budget is also spent by anything else damaging the symbol, and it does nothing for a code whose contrast has fallen uniformly across the whole surface.

The test worth running is one nobody suggests: rescan the oldest printed copy you still have, with an ordinary phone, in the light the code actually lives in. It costs nothing, it is the only measurement of how your ink behaves on your substrate in your environment, and it turns the reprint from a surprise into a scheduled item. Before the next run, the print checklist covers the nine numbers that decide how much margin the new one starts with.

Work Out Which of the Four Actually Failed

Run these in order on a code that has stopped working. The order matters because each step rules out a whole class of cause: the first two separate a code problem from a web problem, and the third separates a problem you can fix from one that belongs to a provider.

1. Scan the Original File, Not the Printed Copy. Open the exported PNG or SVG on a screen and scan it, or decode it with a scanner tool. If the file scans and the print does not, the symbol is fine and the fault is physical - stop here and go to the print checks. If neither scans, the fault is in the destination or the redirect.
2. Read the URL Out of the Code and Look at It. Decode the code and inspect the string. Your own domain means a static code and a web problem you own. A short link on a provider's domain means a dynamic code, and everything after this step belongs to that provider.
3. Open That Exact URL in a Browser. Paste the decoded string into a browser rather than searching for the page. A 404, a parked domain or a redirect to somebody else's site is link rot, and it is repaired at the host or the registrar without touching the print.
4. Check the Account Behind a Dynamic Code. For a provider's short link, sign in and look for an expired trial, a cancelled plan, a failed payment, a deleted link, or a scan allowance that has been reached. If the code works for you and not for customers, the allowance is the first suspect.
5. Inspect the Printed Copy Against a Fresh One. Print the same code again on office paper and scan both side by side. If the new one reads and the old one does not, the print has degraded - faded, scuffed, greased or bleached - and the answer is a reprint rather than anything in software.

If the code never worked at all, this is the wrong page: nothing expired, and the fault is in the size, the contrast, the quiet zone or the destination as it was first generated. Why a QR code is not scanning works through those in order.

How to Print a Code That Cannot Be Switched Off

The arrangement that removes every failure in the table except the printed one is a static code pointed at a short path on a domain you own, with that path configured to redirect to the real destination. The pattern is permanent, the destination stays editable in a hosting panel, and no account can lapse underneath it - the only dependency left is a domain registration you control.

KoloQR, a free QR code generator with circular and custom-shaped QR codes, makes static codes only, which is why it can say the codes never expire without qualifying it: there is no account holding the destination, no redirect to keep alive and nothing to cancel. The generator exports SVG, PDF, EPS and PNG without a signup. It is also why it cannot count scans or re-point a printed code - that is the trade, and it is the whole trade.

• Encode a path you control, not the final page. Something like example.com/menu, short and meaningless. A path named after this year's campaign becomes a lie next year, and the pattern cannot be corrected once it is printed.
• Register the domain for longer than the print run. The dependency has moved to something you own, and something you own can still be forgotten. Auto-renew, on a card that outlives the sign.
• Print a short readable URL beside the code. It rescues the print run if anything in the chain fails, and it serves everyone whose camera does not cooperate. This is the cheapest insurance on the artwork.
• Keep a list of which printed code points where. Two lines per code in a spreadsheet. It is what turns "a customer says the sticker is broken" into a five-minute fix instead of an investigation.
• Diary the reprint for anything outdoors or handled. Codes on stickers, receipts and menus are consumables. Deciding that in advance is cheaper than discovering it from a customer.

None of this makes a dynamic platform a mistake. It makes the expiry question answerable in advance: a static code fails only when the web address behind it does or when the paper wears out, and both of those are yours to manage rather than somebody else's to announce.
