In your account, Dynamic QR Codes display the number of scans to the left of the code with the option to select 'Details' for further scan statistics. Plus, you can tell that your QR Codes are Dynamic when a short URL appears as shown (l.ead.me/bbLviR).
Static QR Codes are identified as Static/Non-trackable, as shown below. They do not provide scan statistics and do not have a short URL. The image below shows how a Static QR Code will appear in your account if an account was created.
If you're still unsure which QR code type you have created, try scanning it. Scanning a Dynamic QR Code will prompt you to open a short URL in your browser (example: Open “l.ead.me” in Safari).
Scanning a Static QR Code will ask you to open the landing page directly (example: Open “qr-code-generator.com” in Safari).
