There’s no hard limit on the Ignored Numbers or Numbers to Replace lists, but a very large list can slow the Tag Wizard page — custom code is a better fit at scale.There’s no limit on how many phone numbers you can add to the Ignored Numbers or Numbers to Replace sections in the Tag Wizard. You can add as many numbers as needed, particularly if you want the Tag to auto-create RingPools for those numbers. Keep in mind that a very large list can lead to longer loading times on the Tag Wizard page. If you’re working with a large number of numbers, consider using custom code instead — specifically
options.doNotSwap or options.numberToReplace — for better management and performance.
