How to use Contact QR Code Generator
Create a QR code that triggers a phone action the moment it is scanned — start a call, open a pre-written text message, or save a contact card. Choose the mode, enter a number, and the code generates instantly in your browser. It is the fastest way to let customers reach you from a poster, business card, receipt, or shop window without typing a single digit.
- Choose the QR type: phone call, SMS message, or contact card.
- Enter the phone number in full international format for best reliability.
- For SMS, optionally add the message text you want pre-filled.
- For a contact card, add a name and email if you want them saved.
- Download the PNG and place it on your print or digital material.

Choosing call, SMS, or contact mode
Each mode encodes a different URI scheme. Call mode uses tel:, which opens the dialer with your number ready to dial — best when you want immediate voice contact. SMS mode uses SMSTO:, opening a new text to your number with optional pre-filled body text, which is ideal for enquiries people prefer to send in writing. Contact mode uses MECARD, a compact contact format that phones offer to save to the address book. Pick call or SMS for a single quick action, and contact when you want the person to keep your details for later.
| Mode | On scan | Best for |
|---|---|---|
| Phone call | Opens dialer with number | Instant voice contact |
| SMS message | Opens text with pre-filled body | Written enquiries, bookings |
| Contact card | Offers to save contact | Sharing details to keep |
Designing a code people actually scan
A QR code is only useful if people understand it and their phone can read it. Always pair the code with a short call to action such as "Scan to call" so its purpose is obvious. Print it at least 2.5 cm (1 inch) wide and keep the white quiet zone around it intact — scanners use that border to find the code. Use the international phone format with a country code so the number dials correctly for visitors and roaming users. Finally, test the printed code with both an iPhone and an Android device before producing it in bulk.
