Verify phone numbers with one WhatsApp message.
Instead of sending an SMS code, let your visitor send a short code to you. The number it comes from is the verified number. No typing, no waiting, no outgoing SMS.
- No number to type
- Works on desktop and mobile
- Pay per verified sign-up
Scan, send, done.
The visitor sees a code
On a computer as a QR code, on a phone as a button. Each visit gets its own short-lived code.
WhatsApp opens with the message
The code is already in the message. One tap on send is all it takes.
Your page confirms the number
Sendity matches code and sender and your page moves on. Sendity does not reply on WhatsApp.
SMS code or WhatsApp message?
| Aspect | Classic SMS code | With Sendity |
|---|---|---|
| Who sends | You send an SMS to the number someone typed in | The visitor sends from their own number |
| Typos | A wrong digit sends the code to a stranger | Not possible, the number comes from WhatsApp |
| Effort | Type number, wait for SMS, type code | Scan and tap send |
| SMS abuse | Bots can trigger expensive SMS to premium numbers | Nothing to abuse on the WhatsApp path, Sendity sends no code by SMS |
| Cost | Every SMS costs, even if it never arrives | Only successful verifications are billed |
Real numbers, less friction.
Only real numbers
Only people who control a WhatsApp account can confirm. Throwaway entries stay out of your list.
Desktop and mobile
On a laptop the phone scans the code. On a phone WhatsApp opens directly.
Clear costs
No SMS bundles and no failed deliveries on your bill. You pay per verified sign-up.
What 250 verified numbers cost
Your first 1,000 credits are free, no credit card needed. Each verified phone number uses 4 credits, and packages from €100 include bonus credits. Your credits never expire. Package prices exclude VAT.
Questions about WhatsApp verification.
Do visitors need WhatsApp?
For this channel, yes. You can allow SMS as a fallback per campaign. It reaches people without WhatsApp but is less secure.
Does Sendity reply on WhatsApp?
No. The visitor sends one message and sees the confirmation on your page. Sendity does not message them back.
Which number do visitors write to?
Visitors write to the shared Sendity WhatsApp number. If your organisation needs its own number, contact us.
What do I receive?
The verified phone number and the name from the WhatsApp profile, as a signed result your site checks. Your verification log in the Sendity app shows each confirmation.
