You printed 500 flyers for your garage sale. You used a "free QR code" from a popular website. The flyers look great. The QR code points to a map of your location. Two weeks after the sale, you scan the code for fun. It doesn't work. You try again. Nothing. The QR code is dead.

Why did it expire? Because you used a dynamic QR code from a platform that deactivates free codes after a certain period. The platform doesn't tell you this upfront. The words "free" and "expiration" are buried in their terms of service. They count on you not reading the fine print. Then, when your code stops working, they offer to reactivate it – for a monthly fee.

QR codes themselves don't expire. A QR code is just a pattern of black and white squares. It's a physical thing (or digital image) that encodes text. That text could be a URL, a phone number, or plain words. The pattern doesn't have a clock. It doesn't know what day it is. The only way a QR code "expires" is if the thing it points to stops working, or if the platform that hosts the redirect deactivates it.

The 14-Day Bait-and-Switch: How the Industry Traps You

Here's a common pattern. QR Code Generator (qr-code-generator.com) advertises a "free" 14-day trial of its plans. Create a dynamic code, print it, and everything works during the trial. What's easy to miss: the free part is a trial. Their page doesn't spell out what happens to a dynamic code you already printed once the 14 days are up — so assume you'll be asked to pay to keep it working.

Why a short window? Because it's enough time for you to print and distribute your materials. It's not enough time for you to realize the code is at risk and demand a refund from your printer. By the time you notice, you've already spent money. Now you have two choices: move to a paid plan — these often run well over $100 a year — or throw away your printed materials and start over. Many people pay. That's the business model.

The pattern repeats across the industry: a free dynamic code for a short window, then a paid plan to keep it alive. Bitly, for example, limits its free plan to a couple of QR codes a month and doesn't let you change where a code points — editing the destination starts on its paid Core plan, which runs $120 a year billed annually. The specifics vary by provider, but the shape is the same: the free tier isn't meant to last.

Truly Free QR is different. Dynamic codes never expire. Not after 14 days, not after a year, not after a decade. I don't have an expiration policy because I don't have a subscription system. There's no timer and no plan to lapse, so nothing deactivates your code automatically. And I won't take it down by hand. The site is designed to be funded by advertising, not by holding your codes hostage.

How to Avoid QR Code Expiration (Step by Step)

Here's exactly how to ensure your QR codes work forever, no matter what.

1. Understand the difference between static and dynamic

Static codes encode the URL directly. They cannot expire because there's no middleman. But you also cannot edit them. Dynamic codes use a redirect. They can expire if the redirect service shuts down or deactivates your code. Dynamic gives you flexibility; static gives you permanence. Choose based on your needs.

2. If you need dynamic, use a provider that doesn't expire

Truly Free QR never expires. Many providers only give dynamic codes a free trial — often around 14 days — and then ask for a paid plan to keep them working. Choose a provider that aligns with your need for permanence. I'm biased, but I built mine specifically to solve this problem.

3. Avoid "free" dynamic codes from unknown providers

If a website offers free dynamic QR codes without showing ads or asking for payment, they're probably expiring them or selling your data. There's no such thing as a free lunch. My site is designed to be funded by display advertising, so the "cost" is ads rather than a subscription. That's transparent. If a site has no visible revenue model, be suspicious.

4. Test your code after 30 days

Even if you trust your provider, test your printed QR codes periodically. Scan them with your phone. Make sure they still work. Providers have been known to change their policy without notice and deactivate old codes. Don't assume permanence. Verify.

5. Own your redirect if possible

The most permanent solution: buy a domain (e.g., yourname.link or yourbusiness.com/qr). Set up a simple redirect server. Each QR code points to a path on your domain (yourdomain.com/qr/menu). You control the redirects via a simple text file. This costs about $15 a year for the domain plus free hosting. No one can expire your codes except you.

6. Use static codes for truly permanent links

If you're linking to your own website that you control forever, static codes are fine. The URL never changes because you own the domain. Your website might change content, but the URL stays the same. Static codes are immune to provider expiration because there's no provider involved. The QR code is just the URL.

Why Truly Free QR Never Expires

Truly Free QR is ad-supported, not subscription-based. The site is designed to be funded by display advertising on the generator page — never on the scan redirect — and there are no subscription prompts.

There's no expiration date attached to your code and no system that deactivates it on a timer. To get rid of a code I would have to go out of my way to delete it, and I won't. It would hurt the site's reputation and drive users away.

If I ever needed to shut down the service (I don't plan to), I would give months of notice and provide a way to export your redirect mappings. You could then set up your own redirect server. But as long as the site runs, your codes run. The commitment is simple: never expire codes, never charge for basic functionality. I'm keeping that promise.

Frequently Asked Questions

Do all dynamic QR codes expire?

No. Only dynamic codes from providers that have expiration policies. Truly Free QR does not expire. Neither do self-hosted dynamic codes (where you control the redirect server). But many providers give dynamic codes only a free trial (often about 14 days) and then ask for a paid plan.

Can I tell if a QR code will expire before I print it?

Read the terms of service carefully. Look for phrases like "free dynamic codes are valid for 14 days" or "temporary QR codes." If the provider doesn't explicitly state that codes never expire, assume they might. I state it clearly across Truly Free QR: our dynamic codes never expire. That's a promise.

What happens to my printed materials if a QR code expires?

They become useless. The only fix is to reprint them with a new code or set up a redirect on a domain you control. If the expired code points to a short URL (like qrprovider.com/abc123), you cannot revive it unless the provider allows you to pay to reactivate. That's why expiration is so damaging – the printed physical material is permanent, but the digital link is temporary.

Does Truly Free QR have any hidden expiration?

No. I've stated it clearly. I built this tool specifically to end the expiration bait-and-switch, so building it in would defeat the whole point. If I ever change this policy (I won't), I would announce it publicly months in advance and grandfather all existing codes. But I have no reason to change. The site is designed to be funded by advertising, not by charging for your codes.

How can I protect myself from expiration if I use a paid provider?

Use a domain you control as an intermediary. For example, buy "yourbusinessqr.com". Set up a redirect from "yourbusinessqr.com/menu" to your actual menu URL. Print that short URL in your QR code. If your paid provider expires or you stop paying, you can change the redirect on your own domain to point somewhere else. Your printed QR code still works because the short URL is yours.

What happens to a paid provider's codes if you stop paying?

With most subscription providers, your dynamic codes stay active only while your plan is current. Stop paying and the code can be deactivated — that's the subscription model. With Truly Free QR, there's no payment to stop, so there's nothing to deactivate.

Don't let your printed materials become trash. Use a QR provider that never expires. Use Truly Free QR. Your flyers, menus, and business cards will still work years from now.
