Is there a tool to verify phone numbers in real time when users submit the Hubspot form?

Twilio lookup Numverify

@SAURABH WANI - thanks for sharing this, Does the costing work on API requests? Say if we have 100 form fills across the site - it will be 100 API calls?

No idea on that. I remember our sales team using it in prev org.

alright, thanks Saurabh

Clearout does that. Along with Twilio. Clearout has emails & another option for phones. With an API that works on a credit system.

Thanks guys

With Prospectoo API's, we can give it a try.
