Verify vs SMS
Both can deliver text messages to phone numbers. They are designed for different purposes.
What each product is
Verify is a purpose-built verification service. You call one endpoint to send a code and another to check it. The platform handles code generation, expiration, rate limiting, and multi-channel delivery (SMS, voice, email).
SMS is a general-purpose messaging service. You compose and send any message to any recipient, with sender profiles, scheduling, keyword routing, and delivery tracking.
When to use Verify
- User sign-up or login confirmation
- Two-factor authentication (2FA)
- Phone number or email verification
- Sensitive action confirmation (payments, password changes)
- You want automatic code generation and expiration
- You need voice call fallback for unreachable phones
When to use SMS
- Notifications, alerts, or reminders
- Marketing messages
- Order confirmations and shipping updates
- Two-way messaging with keyword routing
- Bulk messaging to contact lists
- Scheduled messages

| Channels | SMS + Voice + Email | SMS only |
| Sender ID | Platform-managed | Custom sender profiles |
| Scheduling | No (immediate only) | Yes (up to 30 days) |
| Two-way | No | Yes (keyword routing) |

| Delivery tracking | Session-based (verified/failed) | Per-message status |
| API model | send → check | send → track |
Decision guide
Use Verify if you are confirming a user's identity or ownership of a phone number/email. Verify handles the entire verification flow — you never see the code itself.
Use SMS if you are sending information to the user (notifications, alerts, marketing). You control the message content entirely.
Common combination: Use Verify for login/signup flows and SMS for post-authentication notifications.
