Short answer

How do I validate and clean lead lists with my AI?

Your AI uses the validate_phone tool to check if numbers are active, correct, and formatted properly. It identifies dead lines and pulls carrier or location data so you can fix your lists. You get a clean, actionable dataset for your next campaign.

Where your data lands.

Clean contact data.

The AI sorts your contact data based on the results from the validation check.

VALID

Ready for outreach

The AI identifies numbers that passed all checks. These go straight into your active calling or SMS list.

INVALID

Remove from lists

The AI flags numbers that are disconnected or formatted incorrectly. You can delete these to stop wasting resources.

METADATA

Enriched contact info

The AI pulls carrier and location details for valid numbers. Use this to segment your leads by region or provider.

MANUAL

Needs human review

The AI flags ambiguous results or edge cases. You decide whether to keep these or discard them manually.

The workflow

What your AI does when the list arrives.

Your agent acts as a filter between your raw data and your CRM.

  1. Scan the list

    Your AI reads your provided contact list, whether it is a CSV, a Google Sheet, or a text block.

  2. Verify numbers

    The agent runs every number through the validation tool to check its status and format.

  3. Extract details

FAQ

How the task behaves

  • 01

    Can the AI automatically update my CRM with the new data?

    No. The AI can validate the data and prepare the list, but you must handle the actual writing to your CRM yourself.

  • 02

    Will the AI delete invalid numbers from my original file?

    No. The AI only reads your data and provides the results. It does not modify or delete your original source files.

  • 03

    Does it work with any phone number format?

    The AI uses the tool to check validity, but it is best to provide numbers in a standard format for the most accurate results.

  • 04

    Can I use this to find out where a person lives?

    The tool provides geographic metadata, such as the country or region, but it does not provide specific home addresses.

  • 05

    Can the AI send SMS messages once the numbers are cleaned?

    No. This specific tool is only for validating numbers and retrieving metadata. It does not have messaging capabilities.
