Why wavalid
Built for one job: know if a number is really on WhatsApp
Real-time
Sub-100ms per number, so you catch invalid numbers before they hurt your bounce rate, not after.
195+ countries
Just add the country code. Coverage is global by default.
Organized in batches
Every check is saved to your batch, so you never pay to validate the same number twice. Never sold.
Built to integrate
REST API, MCP server, dashboard, and Chrome extension.

Use cases
See where wavalid fits your workflow
Clean your WhatsApp contact list before you send
Every list collected over time picks up numbers that were never on WhatsApp, were reassigned, or were mistyped. Validate the whole list in one pass and keep only the ones that work.
Read moreValidate numbers before your outreach goes out
Sending to a number that isn't on WhatsApp wastes a send, hurts your delivery rate, and can flag your account. Check the list first, message only the numbers that will actually receive it.
Read moreAdd a validation step to your automated campaigns
An automated flow that messages every contact in a segment doesn't know which ones are actually on WhatsApp. Drop a validation check into the workflow so it only sends to numbers that will receive it.
Read moreKeep your CRM's WhatsApp data from going stale
Contacts collected six months ago aren't guaranteed to still be on WhatsApp today. Numbers get reassigned, people switch devices, accounts get deleted. Re-validate on a schedule so your CRM reflects reality, not the day the record was created.
