Questions
What does the check return for each number?
Whether the number is valid, its line type (mobile, landline, VoIP or toll-free) and the carrier, from live carrier data. Dead and non-mobile numbers come back flagged so you can drop them before you dial or text.
How fast is it?
About 30 seconds for a 1,000-number list. The API answers in under a second per number.
How do I start?
Create an account with Google, start a 7-day free trial (nothing is charged today), then upload a CSV or paste numbers. Plans start at $97/month for 5,000 numbers.
Is my list stored?
No. Lists are processed and returned. We keep usage counts, not your numbers.
