Which fits
Choosing between them
Twilio Lookup may suit you better if
- You already send messages through Twilio and want one bill and one API.
- You need caller name, SIM swap, identity match or reassigned-number checks alongside line type.
- You need fixed and non-fixed VoIP told apart.
- Your vendor review requires a SOC 2 or ISO 27001 report, or a 99.99% uptime SLA, which Twilio offers with Enterprise Edition.
Phone Validator may suit you better if
- You want line type and carrier for half the price per lookup.
- Your team checks lists in spreadsheets or a CRM rather than code.
- You want to know whether a US number was ported, and a fake-number check, in the same lookup.
- You want response times you can check live on our status page.
