In most cases yes: numbers can be ported to a new provider in the US and Canada. Keep your current service active until the port is complete, and ask the new provider to manage the port request.
What about 911 calls on a VoIP system?
Each phone needs a registered location so 911 calls go to the right place. In the US, multi-line systems must support direct 911 dialling and send dispatchable location information under federal rules (Kari’s Law and RAY BAUM’S Act). Ask the provider how they set this up.
