 - **Outbound calling not supported.** Free Vapi numbers are inbound only. Import a number from a supported telephony provider to make outbound calls. See [Outbound calling](/calls/outbound-calling).
 - **Outbound Campaigns require an imported number.** Free Vapi numbers cannot be used to launch [Outbound Campaigns](/outbound-campaigns/quickstart).
+- **Porting out is not supported.** A free Vapi number is provisioned on Vapi's own carrier accounts, not a carrier account you hold, so there is no account number or port-out PIN to request and the number cannot be ported to another carrier.
 - **You are responsible for lawful use.** Obtain the required consent before making outbound calls and follow applicable calling, telemarketing, and do-not-call rules. See the [TCPA consent guide](/tcpa-consent) and [Vapi Terms of Service](https://vapi.ai/terms-of-service).
