How to Scan a QR Code on iPhone
Every iPhone running iOS 11 or later can scan QR codes using the built-in Camera app. No download, no third-party app. Here's how — plus troubleshooting tips if it doesn't work.
3 Steps to Scan a QR Code on iPhone
Open the Camera App
Swipe left from your lock screen, or tap the Camera icon on your home screen. You don't need to take a photo — just open the camera in regular photo mode.
Point at the QR Code
Hold your iPhone so the QR code is fully visible in the viewfinder. Keep it steady — your phone needs a second to recognize the code. You'll see the camera auto-focus on it.
Tap the Notification Banner
A yellow notification will appear at the top of the screen showing the link or action. Tap it to open the website, join a WiFi network, save a contact, or whatever the QR code contains.
Not Working? Troubleshooting Tips
Make sure QR scanning is enabled
Go to Settings → Camera and ensure "Scan QR Codes" is toggled on. On most iPhones this is enabled by default, but it can be accidentally turned off.
Try the Code Scanner from Control Center
If the Camera app isn't detecting the code, try the dedicated Code Scanner. Go to Settings → Control Center and add "Code Scanner" if it's not already there. Then swipe down from the top-right corner and tap the Code Scanner icon. This tool uses a flashlight automatically in low light and is more reliable for difficult-to-scan codes.
Lighting and distance
QR codes need decent lighting and the right distance. If the code is too close or too far, the camera can't focus. Try holding your phone about 6-12 inches (15-30 cm) from the code. In dim environments, the flashlight can help — tap the lightning bolt icon in the Camera app. A 2023 MobileIron survey found 86% of smartphone users had scanned a QR code in the past year, so QR scanning on iPhones is well-tested and reliable under normal conditions.
Damaged or low-contrast codes
QR codes have built-in error correction, so minor damage is fine. But if the code is heavily faded, torn, or printed with low contrast (like light gray on white), it may not scan. If you're generating QR codes for print, always use dark colors on a light background for maximum scannability.
Which iPhones Can Scan QR Codes?
Apple introduced native QR code scanning via the Camera app in iOS 11 (2017), eliminating the need for third-party apps entirely. Any iPhone running iOS 11 or later can scan QR codes natively — that includes iPhone 6s and newer. Apple shipped over 234 million iPhones in 2023 (Statista), and every one of those devices supports native QR scanning. If you have an iPhone 5s or older, you'll need a free third-party QR scanner app from the App Store.
What Types of QR Codes Can iPhone Scan?
iPhones can scan all standard QR code types: website URLs (opens in Safari), WiFi credentials (offers to join the network), contact cards or vCards (offers to save to Contacts), email addresses (opens Mail), phone numbers (offers to call), and plain text (displays the text on screen). According to StatCounter, iOS holds 27.6% of global mobile OS market share as of 2024 — QR code developers routinely target iPhone as a primary scanning device.

Why is my iPhone not scanning the QR code?
First, check that QR code scanning is enabled: go to Settings → Camera and make sure "Scan QR Codes" is toggled on. Also ensure the QR code is fully visible in the viewfinder, the lighting is adequate, and you are holding the phone 15–30 cm from the code. If the Camera app still fails, try the Code Scanner from Control Center (Settings → Control Center → Add Code Scanner).
Can I scan a QR code from a screenshot on iPhone?
Yes. Open the Photos app, find the screenshot containing the QR code, tap the image to view it, then long-press on the QR code area. A menu will appear with an option to open the link or perform the QR code action. This works on iOS 16 and later using Apple's Visual Look Up feature.
Do I need an app to scan QR codes on iPhone?
No. Apple introduced native QR code scanning via the Camera app in iOS 11 (2017), eliminating the need for third-party apps. Simply open the Camera app, point it at a QR code, and tap the notification. According to StatCounter, iOS holds 27.6% of global mobile OS market share as of 2024, and all of these devices can scan QR codes natively.
How do I scan a QR code in low light on iPhone?
Use the dedicated Code Scanner from Control Center rather than the regular Camera app — it automatically activates the iPhone's flashlight in dim conditions. To add it: go to Settings → Control Center → tap the plus icon next to Code Scanner. Then swipe down from the top-right corner and tap the Code Scanner icon whenever you need to scan in low light.
Scanning QR Codes on Android
Most Android phones from 2018 onward can also scan QR codes using the built-in camera app. Open your camera, point it at the code, and a link will appear. If your Android phone doesn't detect QR codes automatically, try the Google Lens feature (available in the Google app or Google Photos) — it works on virtually all Android devices.
Safety Tips When Scanning QR Codes
QR codes are generally safe, but it's worth being cautious. Before tapping a link from a scanned QR code, check the URL that appears in the notification. If it looks suspicious or doesn't match what you expected, don't open it. Be especially careful with QR codes in public places like stickers on poles or ATMs — scammers sometimes place fake QR codes over legitimate ones. If a QR code asks you to download an app or enter personal information, verify the source first.
