Linking Phone Numbers

One of the benefits of the Mobile Web is that its users primarily view it on a phone, allowing the user to quickly and easily make phone calls. It’s an opportunity to help the user and save steps:
<a href="tel:+12065450210">+1 206 545-0210</a>Like any hyperlink, any text could appear between the <a> element to initiate a call. However, the recommendation is to display the phone number.
