Clean data. Clear results.

Know which contact data is real before you use it

ContactValidate checks the names, emails, phone numbers and mailing addresses you already have, tells you whether they belong to one real person, and when that identity was last active.

What we do

One check answers three questions about a contact record.

01

Do these details belong to the person?

Every email, phone number and mailing address is tied to the identity it belongs to, and marked as that person’s primary or secondary value.

JA jordan.avery@…email · primary(555) 010-0147phone · secondaryj.avery@work…email · secondary1200 Example Aveaddress · unverified

02

Does the record hang together?

A record is consistent when no verified value belongs to someone else. One mismatched phone is enough to flag it.

≠ one identity different person

03

Is it still active?

First and last seen dates for the identity show whether a record is current or going stale.

And it hands back clean values.

How it works

From the record you have to a verdict you can act on.

ContactValidate works alongside the systems you already use. Bring contact data from your CRM, a lead list or a signup form.

  1. Send a record

    A name plus any mix of up to 5 emails, 5 phone numbers and 5 mailing addresses, from your code, from Claude or ChatGPT, or by hand in the web app.

    POST /v1/validate
    {
  "name": "Jordan Avery",
  "emails":    [ up to 5 ],
  "phones":    [ up to 5 ],
  "addresses": [ up to 5 ]
}
    • REST API
    • Claude
    • ChatGPT
    • Web app

  2. We match each value

    Every value is checked against identity data drawn from real online activity and tied to the identity it belongs to, or to none.

    • jordan.avery@…JA
    • (555) 010-0147JA
    • j.avery@work…JA
    • 1200 Example Aveno match

  3. Get a verdict per field

    Each value comes back labelled, with a standardized version and the identity’s first and last seen dates, so you know what to keep, fix or drop.

    Primary match×1

    Secondary match×2

    Unverified×1

1 credit per check, whatever the verdict. If we can’t get an answer, the credit is refunded automatically. What a check can and can’t tell you.

  1. Before a campaign

    Revenue and marketing ops

    Check CRM records and imported lists so outreach goes to details that belong to the right person.

    Watch forIdentities not seen in years

  2. On every form fill

    Lead generation

    Screen form fills and purchased leads for made-up or mismatched details before they reach a sales team or a client.

    Watch forDetails that tie to no one

  3. Before outreach

    Collections

    Confirm which phone numbers, emails and addresses on file still tie to the account holder.

    Watch forNumbers that belong to someone else

  4. At account creation

    Signup and onboarding

    Details that tie to no one, or to several different people, are worth a second look before you approve an account.

    Watch forRecords that don’t hang together

  5. Before a mail drop

    Real estate

    Keep buyer, seller and owner lists current so calls and mailers reach the people you mean to reach.

    Watch forSecondary and unverified addresses

  6. Mid-task

    AI agents and workflows

    Give Claude, ChatGPT or your own agent a validation tool it can call on its own, with the price stated before every call.

    Watch forDetails that belong to someone else
