Phone Number to Link: How and Why to Make Phone Numbers Clickable

 

In the era of smartphones, users increasingly expect to interact with websites seamlessly through their mobile devices. One key feature that enhances mobile usability is the ability to click a phone number to call directly — this is what’s commonly referred to as a “phone number link”.

In this article, we’ll explore:

  • What a phone number link is

  • Why it's important

  • How to create clickable phone numbers in HTML

  • Best practices and common pitfalls


What Is a Phone Number Link?

A phone number link is a hyperlink that uses the tel: protocol to allow users to initiate a call by clicking the phone number. It looks like this in HTML:

html
<a href="tel:+1234567890">+1 (234) 567-890</a>

When clicked on a smartphone or compatible device, the number opens in the dialer app, ready to call.


Why Use Phone Number Links?

1. Improved User Experience

Users don’t want to copy and paste a number into their dialer — clickable links eliminate that friction.

2. Mobile Optimization

If your website analytics show a high percentage of mobile users, phone number links help reduce bounce rate and increase conversions.

3. Accessibility

Clickable phone numbers are especially helpful for users with visual impairments or other accessibility needs who rely on assistive technologies.


How to Make a Phone Number Clickable

Here’s a simple step-by-step:

  1. Use the <a> tag with the tel: protocol:

html
<a href="tel:+14155552671">Call Us: +1 (415) 555-2671</a>
  1. Remove formatting in the href but keep it readable for users:

html
<!-- Good for display --> <a href="tel:+442071234567">+44 20 7123 4567</a>
  1. Add schema markup (optional, for SEO):

html
<a href="tel:+14155552671" itemprop="telephone">+1 (415) 555-2671</a>

Best Practices

  • ✅ Use international format (+1, +44, etc.) to avoid ambiguity.

  • ✅ Make phone numbers prominent in the UI (e.g., header or contact page).

  • ✅ Test links on both desktop and mobile.

  • ❌ Don’t use spaces or symbols in the href value.

  • ❌ Don’t forget alternate contact options (email, chat) if users can’t call.


Common Use Cases

  • Business contact pages

  • Emergency or support links

  • Mobile landing pages

  • Email signatures with clickable numbers


Conclusion

Adding phone number links is a small but impactful change that can improve usability, especially on mobile devices. Whether you're running a local business website, eCommerce store, or corporate platform, making it easy for users to reach out with a single tap can significantly enhance user satisfaction and conversion rates.
