How Event Registration QR Codes Work

The QR code will hold your event’s URL – be it an Eventbrite page, a Google form, Luma event, Tally RSVP, or another registration website you may have. Once a person scans the QR code, your website pops up straight away on their device.

This works for both pre-event registration (getting people to sign up) and on-site check-in (directing people to a check-in form or confirmation lookup).

The QR code is static — it points to one fixed URL. As long as your registration link stays the same, the QR code works indefinitely. If you need to change the destination after printing, use a URL shortener (like Bitly) as the QR target, which lets you redirect without reprinting.

Where to Use Event QR Codes

A single QR code for your event can go on multiple materials simultaneously:

• Event poster or flyer — the primary call to action: "Scan to register"
• Email campaign — embed as an image in the invite for mobile recipients to scan off screen
• Venue signage — at the entrance, directing walk-ins to register on the spot
• Printed programme or agenda — links to the live schedule, speaker bios, or feedback form
• Name badge — a unique per-attendee QR for faster staff check-in at the door

QR codes on printed tickets vs digital tickets

Printed tickets: A URL QR on a printed ticket can link to a confirmation page or check-in form. Staff scan it and the attendee's registration record appears. For this to work well, the destination URL needs to be unique per attendee — which means generating individual QR codes for each attendee. The bulk QR code generator handles this: upload a CSV with one confirmation URL per row and download all QR codes as a ZIP in one go.

Digital tickets: However, when it comes to the digital tickets, the QR codes that they generate are created automatically by the software used. In regards to the QR codes discussed here, however, they can be used for the alternative situation – making sure that people go to the registration page in the first place.

Step-by-Step: Create Your Event Registration QR Code

Step 1: Copy your registration link Get the full URL of your event registration form — Eventbrite, Google Forms, Luma, Tally, or your own site. Make sure the link is publicly accessible without login.

Step 2: Open the event QR generator Go to genqrfree.com/qr-code-generator-for-event. The URL tab is pre-selected. Paste your link into the input field.

Step 3: Customize for your event branding Click Set Colors and implement the color scheme of your event. A branded QR code will be more purposeful when used in a poster. The background should be either white or light-colored for better readability when scanned. Your event’s logo can be added to the middle section of the QR code, which should not occupy more than 30% of its surface area. Step 4: Download the right format

• PNG at 1000px — for digital use (email, social, website)
• PNG at 2000px — for standard print (A4 flyers, table cards)
• SVG — for large-format printing (banners, A-frame signs, stage backdrops)

For print specs and minimum size rules, the print QR code guide has the full breakdown.

Design Tips for Event Materials

Add a clear label. Print "Scan to register" or "Scan to check in" directly above or below the QR. Attendees are more likely to scan when the action is obvious.

Use event branding. Add your event logo to the QR code — a branded QR on a poster or badge looks intentional rather than generic. The generator handles error correction automatically when a logo is uploaded.

Print it on event posters and programs. For full print specs — file formats, minimum sizes, quiet zone rules — see the guide on QR codes for posters and flyers.

Leave white space around the QR. The quiet zone — the white border around the QR pattern — is part of how scanners locate the code. Don't let other design elements crowd it. A 4px minimum margin at print size; more is better.

Test at real scanning distance. For a venue poster scanned from 1 metre away, the QR needs to be at least 6 × 6 cm. For a badge scanned from 30 cm, 2.5 × 2.5 cm is the minimum. Print a test page and scan it before the full print run.

Use high-contrast colors. Dark QR on white background scans most reliably. If you use a brand color, make sure it's dark enough — mid-tone grays, greens, and blues work; pastels and yellows don't.

Frequently Asked Questions

Can I use the same QR code for multiple events? Only if the registration URL is the same — which it won't be. Each event should have its own registration link, and therefore its own QR code. Regenerating takes under a minute, so there's no reason to reuse one.

What link should I use — my registration form URL or a short link? Both will work fine technically. The short url (Bitly, t.ly) is nice because it gives you the ability to update the destination link even if you printed one and it has a little bit more room in the QR code, which means that the QR code isn’t quite as dense as the other. For most events, you don’t need to use the short url format.

How do I make sure the QR code is large enough to scan from a distance at a venue? The golden rule is always 10:1 — the QR code needs to be at least 1/10 of the scanning distance. If scanning from 1 m away, it has to be no smaller than 10 cm square. From 3 m away (as on a billboard), no less than 30 cm square. Always get SVG files above A4 size.
