Cognalys for Web

Service overview

Cognalys provides a platform for verifying mobile phone numbers that avoids dependence on region-specific messaging. Instead of relying on SMS — which can be expensive and limited by country — it uses missed-call verification to confirm ownership of a number, reducing both complexity and cost.

How verification works

Traditional SMS-based checks often vary by location and carrier. Cognalys replaces those text messages with a missed-call method: the system places a short call that the user receives (or returns), which serves as the verification signal. This approach is designed to work consistently across markets.

Global availability

The service operates internationally, covering more than 200 countries, so you can use the same verification approach across multiple regions without implementing region-specific fallbacks.

Pricing and limits

• Paid plans — start at $12 per month; recommended if you routinely perform more than 15 verifications each day.
• Free tier — available for light use, with an effective limit around 15 mobile verifications daily.

Suggested alternative

• Deseat.me — free option you can consider as an alternative.
