# Is There a Maximum Limit to the Number of Phone Numbers That Can Be Added to the Ignored Numbers or Numbers to Replace List?

> 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.
