Validate phone numbers with confidence.
Paste US phone numbers and instantly see whether they're valid plus carrier, line type, location, and caller name — powered by Numverify and Twilio Lookup. No account, no signup.
Validation that actually works
We strip formatting, accept +1 and 10/11-digit input, and only call paid APIs once a number passes basic sanity checks.
Bulk lookups in seconds
Paste a whole list — one number per line — and get carrier, line type, location, and CNAM for every valid number in one click.
Copy or export the result
Every batch can be copied as plain text or exported as a CSV that opens cleanly in Sheets, Excel, or your CRM.
