It depends on the country.

United States: yes. United States numbers, including Toll-Free numbers, can be ported to TelHarbor. TelHarbor coordinates the process with your current carrier and your number keeps working.

Costa Rica and the rest of the Americas: landline numbers are not ported to IP telephony. In those cases a new number is assigned, and we recommend leaving the old one forwarded while you tell your customers about the change.

Before you sign up, tell us which numbers your company publishes: if your operation depends on keeping a number, it is better to review that at the beginning and not at the end.
