Twilio Lookup helps you know the details behind a phone number. Using Lookup, you can do things like:
- Validate and format phone numbers for local or international use
- Identify a number's carrier and type: landline, mobile, or VoIP
- Look up the name of the number's owner, if available (U.S. only)
- Determine if associating that number with your customer exposes you to fraud or a security risk
