Phone Number Recognition

suggest change

Mobile platforms like iOS automatically recognize phone numbers and turn them into tel: links. While the feature is very practical, the system sometimes detects ISBN codes and other numbers as telephone numbers.

For mobile Safari and some other WebKit-based mobile browsers to turn off automatic phone number recognition and formatting, you need this meta tag:

<meta name="format-detection" content="telephone=no">
