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 the 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, you can use HTML tags that don't apply any additional style.
For example: 555-<span>444<span>-3333.
Can I have a white-labeled version of my swap code?
Yes. Use the instructions above when logged into CallRail via your white label domain to access a white label version of your swap script.
