Short answer

How can I format international phone numbers with my AI?

Your AI uses Namsor to determine a contact's origin and then applies the correct international formatting to their number. You'll get clean, dialable data through these steps.

The results you get.

Clean contact data.

When your agent processes a list, it delivers these specific outcomes.

VALIDATED

Standardized numbers

The AI converts raw digits into the correct international format. You get a clean list ready for any CRM or dialer.

IDENTIFIED

Origin detection

The agent determines where a number belongs based on the person's name. This prevents country code errors.

CLEANED

Removed noise

Extra characters and local prefixes are stripped away. Your data becomes consistent and easy to search.

HUMAN

Manual review

If the AI can't find a clear origin, it flags the entry. You decide how to handle these specific cases.

The workflow

What your AI does when a number arrives.

The AI follows a logical path to turn a string of digits into a usable contact.

  1. Find the origin

    The agent looks at the contact's name to figure out which country the number belongs to.

    get_origin

  2. Format the digits

    Once the origin is known, the AI applies the correct international standard to the number.

    format_phone

  3. Check the result

    The AI runs the formatted number through a check to ensure it follows the right pattern.

    format_phone

  4. Flag missing info

    If the name or number is too vague to determine an origin, the AI stops and tells you.

    get_origin

FAQ

How this task behaves.

  • 01

    Can the AI update my CRM automatically?

    No. The AI prepares the formatted data, but you must be the one to push those changes to your CRM.

  • 02

    What if the name and number don't match?

    The AI uses the available origin data to try and format it, but it won't guess if the information is too contradictory.

  • 03

    Does the AI change my original files?

    No. The AI only reads your data and provides new, formatted versions. It never modifies your source files.

  • 04

    Can it format numbers without a name?

    It can try, but accuracy is much higher when the AI can use the name to determine the origin.

  • 05

    Will it fix typos in the digits?

    It can fix formatting like missing country codes, but it cannot fix a number that is missing digits.
