THE PRACTICAL QR HANDBOOK
Expired QR code? How to find the cause and fix it
Diagnose a broken printed QR code and understand your options.
Start with the right destination
Scan the printed symbol and inspect the URL before opening it. Identify the hostname of the redirect service, then check whether the final website works independently. A damaged print, missing destination, expired domain, or paused redirect can all look like an expired QR code.
If a provider controls the encoded address, only that provider can restore its redirect. Contact support and review the original plan terms. You cannot remotely rewrite the pixels on printed paper. If restoration is impossible, use replacement stickers or reprint and choose an address you control for future materials.
Diagnose before paying or reprinting
Write down the exact encoded URL. Most camera apps show a preview; a trusted offline QR reader can expose the contents without following the link. Do not paste account keys or private invitation URLs into public decoder websites. Compare the hostname with your original receipt, design files, or browser history. The company that printed the artwork may be different from the company controlling the redirect.
Next, distinguish a scanning failure from a website failure. If the camera cannot recognize the symbol, try a clean, flat copy in better light. If it recognizes a URL but the browser shows an error, check the destination on another network and device. A certificate error, domain renewal problem, or deleted menu file requires a different fix from an expired generator trial.
If the encoded URL uses a domain you own, a website administrator may be able to restore that path or create a redirect. If another provider owns it, ask whether the original link can be restored and request the terms in writing. Export your destination list while account access is available. For replacement stickers, cover the entire old symbol and its clear border so cameras do not detect two competing codes.
Build and test it step by step
- Decide what a person should accomplish after scanning. Write a short call to action in ordinary language, then prepare the destination before generating the code.
- Open the destination on a phone using mobile data. Check loading speed, text size, navigation, and whether anything requires an unexpected login. Fix those issues before printing.
- For a web destination that may change, create a Forever QR account and save the secret manage link somewhere safe. Create a code with a descriptive label so you can identify it later.
- Download the SVG for a print designer or the high-resolution PNG for a simple document. Keep the original file with your artwork and record where you intend to distribute it.
- Print a proof at its final size. Scan it using several phones, at realistic distances, under both good and imperfect light. Follow the entire journey rather than stopping when the camera recognizes the symbol.
Make the printed code easy to scan
Leave a clear border around the symbol. QR readers use this quiet zone to separate the code from surrounding artwork. Keep at least four modules of empty space on every side. Do not crop that space when placing the image into a design tool. A dark foreground on a plain light background is the most dependable starting point. Decorative colors can work, but a color combination that looks attractive on a screen may lose contrast on paper.
Size depends on viewing distance, payload density, print quality, and the camera. For handheld material, start around 25–30 mm wide and test a physical proof. Increase the size for distant signs. Avoid putting a fold, staple, logo, or reflective coating through the symbol. When printing on textured stock, ask the printer for a sample. A successful scan of a large preview on your laptop does not prove that a small printed version will work.
Maintain the experience after printing
Keep an inventory of the places where your code appears and review the destination periodically. When information changes, update the destination or its content and scan an old printed copy again. Give each campaign a clear label rather than relying on memory. Keep a readable web address and a contact method nearby so people have an alternative if scanning is difficult.
Save your secret manage link in a password manager or download the key file and store it securely. Anyone with that key can manage the account. Forever QR cannot email a replacement because accounts do not require an email address. Losing access does not stop existing codes from redirecting, but it prevents you from editing their destinations.
Frequently asked questions
Can I change the destination after printing?
A dynamic web redirect can be edited through its account. A static symbol cannot be rewritten after printing. Check what the symbol actually contains before choosing a workflow.
Will the code work forever?
Forever QR keeps codes redirecting for as long as the service exists, with exceptions for abuse or illegal content. If the service shuts down, we commit to at least 12 months notice and an export of destinations. The linked website must also remain available.
What should I check before a large print run?
Verify the destination, scan a physical proof, check contrast and clear space, and save your account key. Ask someone unfamiliar with the project to try the complete flow. Their feedback often reveals unclear instructions that the designer has stopped noticing.
