Types of QR Codes: Formats, Use Cases & Which to Pick

A QR Code's type is defined by two independent decisions: the structural format that holds the data, and the destination content that opens when someone scans it.

What determines a QR Code’s type?

A QR Code's type depends on two independent variables: structural format which is the pattern and version, such as Model 2 or Micro QR Code, and destination content, the action triggered when scanned, such as joining a WiFi network or opening a webpage. This page covers 7 structural formats and 21 destination-content categories currently recognized by scanners.

Most QR Code type lists conflate these two variables, which is why unrelated categories like "Facebook QR Code" and "Micro QR Code" end up grouped together. The variable that actually determines whether a QR Code stays functional after printing is whether it's static or dynamic, and that's independent of both.

According to Uniqode's State of QR Codes 2026 report, 98% of marketers report a positive impact from QR Codes, and 60% plan to increase usage in the next year.

What are the different types of QR Codes?

QR Codes support more than 20 content types, each defined by what happens the moment someone scans. Start by choosing the destination you need as the structural format underneath rarely changes what you actually have to build.

• Website QR Code: Opens any URL when scanned, from a homepage to a single landing page. Marketers use it most often because it fits nearly any campaign, from print ads to product packaging.
• PDF QR Code: Hosts a document instead of a link, so a menu, brochure, or spec sheet opens directly on the scanner's phone. On a dynamic code, swapping the file updates every printed copy at once.
• Digital Business Card (vCard): Saves a contact card straight to the scanner's phone in one tap, including name, number, email, and title. Sales teams and recruiters use it to replace paper business cards at events.
• WiFi QR Code: Joins a network instantly when scanned, no password typing required. Coffee shops, hotels, and offices post it at the entrance so guests connect through the phone's camera.
• Location QR Code: Opens a map app with directions already loaded, usually to a street address or venue. Real estate signs and event flyers use it to skip typing an address into a phone.
• Restaurant Menu QR Code: Opens a live, editable menu instead of a printed one. Restaurants update prices and items without reprinting a single table tent.
• Landing Page QR Code: Opens a dedicated campaign page built for one specific call to action, instead of a general website.
• App Download QR Code: Detects the scanner's operating system and routes iOS to the App Store, Android to Google Play, from one code.
• Email QR Code: Opens a pre-filled email draft, subject line included, in the scanner's default mail app.
• Message QR Code: Opens a pre-filled text message with the recipient number and body already set.
• Social Media QR Code: Links directly to one profile, or to several through a single landing screen.
• Coupon QR Code: Delivers a digital discount code with an expiration date attached.
• Event QR Code: Shares event details and an RSVP link in one scan.
• Video QR Code: Plays a video file directly instead of opening a webpage first.
• Image QR Code: Opens a full-resolution image or photo gallery.
• MP3/Audio QR Code: Plays an audio file or opens a streaming link, such as Spotify or Apple Music, without downloading anything.
• Text QR Code: Displays plain text on screen, no app or webpage required.
• Payment QR Code: Opens a payment app with the amount and recipient already filled in.
• meCard QR Code: Saves a lighter contact card, with fewer fields than a full vCard.
• Call QR Code: opens the phone's dialer with a number already entered.
• Rating/Feedback QR Code: links to a review or survey form right after a purchase or visit.

What are the different types of QR Code formats?

A QR Code's structural format determines its size, data capacity, and which scanners can read it. Seven formats exist, and one of them handles nearly every business use case on this page.

• Model 1 is the original 1994 format. It holds less data than later formats and is largely obsolete today.
• Model 2 is the standard format used by virtually every QR Code generator today.
• Micro QR Code shrinks the footprint for low-data, space-constrained labels.
• rMQR (Rectangular Micro QR), standardized as ISO/IEC 23941:2022, fits narrow spaces like test-tube labels and cable tags.
• iQR Code supports both square and rectangular shapes and holds more data than a standard QR Code.
• SQRC (Secure QR Code) splits its payload into a public area and a restricted private area.
• FrameQR reserves a customizable canvas inside the code for a logo without breaking scannability.

HCC2D (High Capacity Colored 2D) is an emerging color-based format, still niche outside specialized applications.

What are QR Code error correction levels?

QR Codes use one of four error correction levels, defined by ISO/IEC 18004. Each level trades data capacity for damage tolerance.

‍

What's the difference between a static and dynamic QR Code?

Every QR Code is either static or dynamic and that distinction matters more than any other type classification.

A static QR Code's destination is permanently fixed at creation. A dynamic QR Code's destination can be updated at any time, even after printing. For most real-world applications, dynamic is the right choice.

Dynamic QR Codes don't encode a destination directly. They store a short redirect URL you control, update that redirect whenever you need to, and track every scan, all without reprinting the code. That's why dynamic QR Codes are the standard for menus, packaging, business cards, posters, and any code that needs to stay functional after distribution.

Static QR Codes embed the destination directly in the code. Once printed, nothing changes, no edits, no redirects, no tracking. If the linked page moves or the offer updates, the code becomes useless and existing copies can't be fixed. Static codes work only for content that will never change, like a Wi-Fi password or a permanent contact card.

The QR Code "types" people search for like Facebook QR Code, WhatsApp QR Code, restaurant QR Code aren't truly different types. Every QR Code is either static or dynamic. The destination content varies; the underlying structure doesn't.

That distinction has real consequences. According to Uniqode's State of QR Codes 2026 report, 75% of consumers scan QR Codes to find information, yet only 36% of marketers deliver it. Static codes that break when a page changes contribute directly to that gap. Dynamic codes are updatable, retargetable, and monitored and help close this gap.

‍Which QR Code type should you use?

Three questions decide your answer: what does the code need to do, will you need to change or track it, and where will it live physically?

‍Is it safe to scan an unfamiliar QR Code?

Static, unbranded QR Codes are the most vulnerable to spoofing. According to Uniqode's State of QR Codes 2026 report, 58% of consumers feel confident QR Codes are safe to scan but the threat landscape tells a different story. In a FLASH alert coordinated with DHS/CISA dated January 8, 2026, the FBI warned that the North Korean state-sponsored group Kimsuky embedded malicious QR Codes in spearphishing emails targeting U.S. think tanks, NGOs, and government-adjacent organizations.

The scale of the problem is accelerating. Quishing incidents grew fivefold in just three months, from 46,000 to 250,000 between August and November 2025, according to Kaspersky data cited in a February 2026 StrongestLayer report. Alan LeFort, CEO and co-founder of StrongestLayer, identified the issue as structural: "The industry spent billions to scan QR codes, and attackers still won. This isn't a tuning problem. It's an architectural one."

Unbranded static QR Codes sit at the center of that architectural problem. Their destinations can't be verified before scanning and can't be revoked after printing, two properties that make them the highest-risk format in circulation.

1. Check the domain shown in the preview before tapping through.
2. Look for a business logo or branded frame as a trust signal.
3. Avoid codes on unsolicited mail or stickers placed over other codes.
4. Confirm the destination page loads over HTTPS.

How is a QR Code different from other 2D barcodes?

A QR Code is a two-dimensional barcode that stores data in a square grid of black-and-white modules. Four other 2D symbologies compete with QR Codes for different use cases.
