Short answer

How can I use AI to verify contact info?

Your AI uses AbstractAPI to check if email addresses, phone numbers, and VAT numbers are real and correctly formatted. This prevents bad data from entering your systems. You'll see how the results are organized below.

Data outcomes

Where your data lands.

The AI sorts every piece of contact info into one of these four buckets.

VALID

Clean data

The AI confirms the contact details are legitimate. You get a clear signal to proceed with your work.

INVALID

Error flags

The AI catches typos or fake entries. It points out exactly which field failed the check.

REVIEW

Human check

If the data looks suspicious or ambiguous, the AI flags it for you. You decide if it's safe to use.

LOG

Audit trail

Every check is recorded. You get a history of what was verified and when.

The workflow

What your AI does when contact data arrives.

Instead of you checking every field, your agent runs these checks in order.

  1. Email check

    The AI checks if an email address is real and correctly formatted.

    validate_email

  2. Phone check

    Your agent confirms that phone numbers are valid and reachable.

    validate_phone

  3. VAT check

    The AI verifies that VAT numbers are legitimate for tax compliance.

    validate_vat

  4. Final triage

    The AI compares all results to decide if the contact is safe or needs a human look.

FAQ

How this task behaves.

  • 01

    Can the AI fix typos in my email list automatically?

    No. The AI identifies which emails are invalid, but you must manually correct the typos yourself.

  • 02

    Does the AI delete invalid contacts from my CRM?

    No. The AI only reports the results of the validation. It does not have permission to delete or modify your existing records.

  • 03

    Can it validate international phone numbers?

    Yes, it uses the validation tool to check the legitimacy of the numbers provided.

  • 04

    What happens if a VAT number is partially correct?

    The tool will flag it as invalid. The AI will then report that the specific VAT number failed the check.

  • 05

    Can I use this to verify physical addresses?

    No. This connector is specifically for email, phone, and VAT validation.
