Why isn’t my telephone number swapping?
Have you cleared your cookies, or tried accessing the website in a private browsing session? The most important part of testing dynamic number insertion is to simulate the experience of a first-time visitor before testing. Otherwise, the swap code will detect you as a visitor to the website from a previous session.
How do I prevent a number from swapping on my website?
If there is a specific place on your website where you don't want a number to swap, you're able to update the telephone number in your source code so that our swap script doesn't recognize it. In the number that you do not want to be swapped, use HTML tags that don't apply any additional style.
For example: 555-<span>444<span>-3333.
Can I use dynamic number insertion in an iframe?
We do not recommend installing our dynamic number insertion script in an iframe since they run independently from the rest of a website. This could cause an inconsistent experience for website visitors, and they could potentially see two different tracking numbers on the same website. CallRail's swap script can still be installed on websites that use iframes, but any number within an iframe won't swap.
