You can check if your phone number is portable to Twilio in two ways:
- Console: Use the web-based portability checker for quick, one-time checks without coding
- API: Use the Portability resource for programmatic checks and integration into your applications
Both methods provide the same portability information and show you whether you can port your number to Twilio.
Use the Twilio Console to quickly check if your phone number is portable. This method is done directly within the console and doesn't require any coding.
To check portability in the Console:
- Go to the Portability Checker in the Console.
- Enter your phone number in E.164 format (for example, +1234567890).
- Click "Check Portability" to see if you can port your number to Twilio.
The Console shows you:
- Whether you can port the number.
- Any reasons why you can't port the number (if applicable).
- Next steps for starting the porting process.
Info
The Console portability checker provides the same information as the API below, but with a user-friendly interface that doesn't require authentication or coding.
Use the Portability API to check if you can port a number to Twilio programmatically. This is useful when you need to:
- Check portability for multiple phone numbers
- Integrate portability checks into your application or workflow
- Automate the porting process
The Portability API provides detailed information about:
- Whether a phone number is portable
- Reasons why a number can't be ported
- Whether a PIN and account number are required for porting
