How do I add a click-to-call button to my website?

A click-to-call button lets visitors tap a phone number or button and start a call from a compatible device. It is particularly useful for businesses that receive enquiries by phone.

1. Use a tel: link

The basic HTML structure is:

<a href=”tel:+441234567890″>Call Us</a>

Replace the example number with your business phone number, including the country code. The tel: link tells the device that the link should be treated as a telephone number.

2. Add the link to a button

If your website builder supports buttons, add the phone number as the button’s link:

Button text: Call Us
Link: tel:+441234567890

On a custom website, you can style the link to look like a button using CSS.

3. Use the correct phone number

Check that the number is accurate and includes the appropriate country code. Avoid accidentally adding spaces, extensions or other characters that your website builder may not handle correctly.

If your business has different numbers for different departments, link each button to the appropriate number.

4. Place the button where visitors need it

Common locations include:

  • The website header

  • The homepage

  • The Contact page

  • Service pages

  • A mobile navigation menu

The button should be easy to find without appearing repeatedly in a way that makes the page difficult to use.

5. Test the button

Test the link on a smartphone and other relevant devices. Check that tapping the button opens the device’s calling interface with the correct number.

Also check the button after publishing the website, rather than testing only inside the website editor.
