Phone verification your users actually receive — delivered over WhatsApp to every Indonesian carrier, at a flat Rp 100 per OTP. Self-serve API key in minutes: no sales call, no enterprise setup.
What you actually pay to deliver one WhatsApp verification to an Indonesian number. Twilio and Vonage are built for global enterprises, and you pay for that scope whether your app needs it or not.
| Provider | Price per OTP | Billed in | Notes |
|---|---|---|---|
| OTP SpaceBuilt for Indonesia | Rp 100 | IDR (Rupiah) | WhatsApp-native delivery to every Indonesian carrier. Flat rate at any volume, billed in Rupiah. Self-serve API key in minutes — no sales call, no minimum. 10 free OTPs on signup; Email OTP from Rp 20. |
| Twilio Verify | ≈ Rp 800+* | USD | Powerful global platform, but overkill for a single-market Indonesian app. Per-verification fee plus a per-message WhatsApp fee in USD, exposed to the exchange rate, with enterprise setup you'll mostly not use. |
| Vonage Verify | ≈ Rp 900+* | USD | Another global enterprise platform priced in USD. Per-verification fee plus messaging charges; you also pay for failed attempts. |
| Verihubs | ≈ Rp 300+* | IDR (Rupiah) | Local aggregator, but enterprise-oriented — sales-led onboarding and volume commitments before you can send. |
| Fazpass | ≈ Rp 300+* | IDR (Rupiah) | Local multi-channel aggregator; pricing varies by channel and negotiated volume, usually via sales. |

For an Indonesian app that needs one thing — a WhatsApp OTP your users actually receive — that scope is cost and complexity you don't use.

Not a cheap knockoff — the right tool for the job.
Self-serve API key, then one REST call to send. No sales call, no onboarding queue — it works from any language.
