Short answer

How can I use my AI to verify phone numbers?

Your AI triggers an SMS OTP message to the user's provided number to confirm it belongs to them. This process happens instantly during your lead capture flow. You'll get a clean list of verified contacts.

The results

Where your data lands

The outcomes of running a verification check.

VALIDATED

Confirmed contact data

The AI uses the OTP tool to ensure the number is active. You get a clean list of reachable leads.

REJECTED

Filtered fake numbers

If the user fails the SMS check, the AI flags the lead as invalid. This prevents junk data from entering your CRM.

HUMAN

Manual intervention needed

If a user fails the OTP multiple times, the AI can hand the conversation over to you. You decide how to handle these edge cases.

LOGGED

Audit trail created

Every sent code and verification attempt is tracked. You can review the history of every phone number attempt.

The workflow

What your AI does when a user provides a number.

The AI manages the technical handshake between your chat interface and the mobile network.

  1. Capture number

    The AI identifies when a user has shared a phone number during a conversation.

  2. Trigger OTP

    The agent sends a unique code via SMS to the user's device to prove ownership.

    send_otp

  3. Validate code

    The AI waits for the user to type the code back into the chat to confirm it matches.

    send_otp

  4. Finalize lead

FAQ

How this task behaves

  • 01

    Can the AI send messages other than OTP codes?

    No. This specific tool is strictly for sending one-time passwords to verify phone numbers.

  • 02

    Does the AI decide which phone number to verify?

    The AI follows your instructions. It only sends a code to the specific number you or the user provides.

  • 03

    Can the AI delete my existing contact list?

    No. The tool only has the capability to send SMS messages. It cannot modify or delete your database.

  • 04

    What happens if the user never receives the code?

    The AI cannot fix carrier issues. You will need to step in and handle the user manually if the SMS fails to arrive.

  • 05

    Can I use this to send marketing blasts?

    No. The tool is designed for single-use verification codes, not bulk messaging.
