Yes, you can port your existing toll-free number with most service providers. Porting a phone number to JustCall is a very easy process, and we help businesses with the complete process. We need some ownership verification documents from your end to get you the same toll-free number at JustCall. The duration of the process depends upon the country of the number to be ported. There is no downtime as the number remains active on your current provider until it is ported to JustCall. So, you basically have the same phone number but with added features.
