Our platform offers several phone validation tools that can check mobile number status and line type, but none specifically verify WhatsApp account association. You can use ClearoutPhone to check if a phone number is active and determine the line type (mobile vs landline). We also have mobile validation tools through Trestle that verify phone numbers and provide activity scores. Are you looking to validate phone numbers for outreach purposes, or do you specifically need WhatsApp verification for a particular use case?

We offer several phone validation tools for outreach purposes. You can use ClearoutPhone to check if numbers are active and identify line types (mobile vs landline). Trestle provides more detailed validation with phone activity scores, line types, and contact grades. For finding mobile numbers, our Clay Enrichments can help you discover numbers associated with email addresses or social profiles. However, we don't currently have a specific tool to verify if a number has a WhatsApp account associated with it.

Hey Noor, thanks for reaching out! We do offer enrichments like "Validate Phone Number" from Trestle that will allow you to validate a phone number. However, when you say WhatsApp verification, I'm not sure I'm exactly following this process. If you had to verify if a company is WhatsApp verified, how would you do so?

owen (Clay) I need to verify if there is a whatsapp created on the mobile phone number. Basically, there is a chance if anyone has not created a whatsapp so I need to verify if the mobile number I have pulled out via clay, is there a whatsapp associated with that number or not.

Ah got it! Right now, WhatsApp doesn’t offer a public API that allows you to directly check if a phone number is registered. However, if you're using the WhatsApp Business API (via providers like Twilio, 360dialog, or Meta), there are indirect ways to verify this—for example, by attempting to send a message and checking if it fails due to the number not being registered. That said, this kind of check isn't officially supported for discovery purposes, and it would require setting up a verified WhatsApp Business account. Let me know if this clears things up!
