How to Automate Phone Validation with Zapier and RealValidito

May 22, 2026 - by RealValidito

If you use Zapier to automate your business workflows, you can now add real-time phone validation to any Zap — without writing a single line of code. By connecting Zapier with RealValidito, you can automatically validate phone numbers, check DNC status, and filter out bad contacts before they reach your CRM, email platform, or SMS tool.

This guide shows you exactly how to set it up — step by step.

Why Phone Validation Matters in Zapier Workflows

Zapier connects over 6,000 apps. Every day, millions of leads flow through Zapier from Facebook Lead Ads, Google Sheets, Typeform, Webflow, and dozens of other sources. The problem? None of these sources validate the phone numbers they collect.

Without phone validation in your Zapier workflows, you risk:

  • Adding fake or disconnected numbers to your CRM
  • Sending SMS to landlines that can never receive texts
  • Calling contacts on the Do Not Call (DNC) Registry — a TCPA violation
  • Wasting money on invalid leads that will never convert
  • Damaging your SMS sender reputation due to high bounce rates

RealValidito solves this by adding a real-time phone validation step to any Zap — checking every number before it reaches the next step in your workflow.

What RealValidito Validates

Every RealValidito API call returns the following in under 200ms:

  • Is Valid — whether the number is a real, active US or Canada phone number
  • Line Type — Mobile, Landline, VoIP, Toll-Free, or Unknown
  • Carrier — T-Mobile, Verizon, AT&T, and more
  • DNC Status — whether the number is on the National Do Not Call Registry
  • TCPA Litigator Flag — whether the number is linked to known TCPA lawsuit filers
  • Location — city, state, ZIP code, and country

Use this data in your Zap to filter, tag, route, or block contacts automatically.

3 Real-World Zapier + RealValidito Workflows

Workflow 1 — Facebook Lead Ads → Validate → CRM

When a new lead comes in from a Facebook Lead Ad, validate their phone number before adding them to your CRM:

  1. Trigger: New lead from Facebook Lead Ads
  2. Action: Webhooks by Zapier → POST to RealValidito
  3. Filter: Only continue if is_valid = true AND is_dnc = false
  4. Action: Add to HubSpot / Salesforce / GoHighLevel

Result: Only clean, valid, DNC-free numbers enter your CRM.

Workflow 2 — Google Sheets → Validate → Mark Results

Automatically validate a list of phone numbers in Google Sheets and write the results back:

  1. Trigger: New row added in Google Sheets
  2. Action: Webhooks by Zapier → POST to RealValidito
  3. Action: Update Google Sheets row with line_type, is_dnc, carrier

Result: Your spreadsheet is automatically enriched with validation data for every new number.

Workflow 3 — Typeform / Webflow Form → Validate → SMS Tool

When someone fills out a form on your website, validate their phone before adding them to an SMS campaign:

  1. Trigger: New submission in Typeform or Webflow
  2. Action: Webhooks by Zapier → POST to RealValidito
  3. Filter: Only continue if line_type = Mobile AND is_dnc = false
  4. Action: Add to SMS campaign in Klaviyo, ActiveCampaign, or Twilio

Result: Only mobile, DNC-free numbers enter your SMS campaigns — protecting your sender reputation and keeping you TCPA compliant.

How to Set Up RealValidito in Zapier

Step 1 — Get Your RealValidito Integration Key

  1. Create a free RealValidito account — you get 1,000 free credits, no credit card required.
  2. Log in and go to Account Settings from the top navigation menu.
  3. Scroll to the GoHighLevel & Zapier Integration section.
  4. Click Generate Key and copy your rv_live_... key immediately.

Step 2 — Set Up the Webhook in Zapier

  1. Log in to zapier.com and click Create Zap.
  2. Set your Trigger — for example: new row in Google Sheets, new Facebook lead, or new form submission.
  3. Add an Action step and search for Webhooks by Zapier.
  4. Select Custom Request as the action event.
  5. Set the Method to POST.
  6. Set the URL to: 
    https://app.realvalidito.com/zapierapi/phone_dnc_lookup
  7. Under Headers, add: 
    Authorization: Bearer rv_live_your_key_here
Content-Type: application/json
  8. Under Data, set: 
    {"phone": "your_phone_field_here"}

    (Map the phone field from your trigger step.)

  9. Click Test & Continue — Zapier will show the full response including is_valid, line_type, is_dnc, and is_tcpa.

Step 3 — Add a Filter Step

After the webhook action, add a Filter by Zapier step:

  • Continue only if is_valid = true
  • AND is_dnc = false
  • AND line_type = Mobile (if running an SMS campaign)

This ensures only clean, valid numbers reach the next step in your Zap.

API Response Example

Here is what RealValidito returns for each phone number:

{
  "status": "success",
  "phone": "8005551234",
  "is_valid": true,
  "line_type": "Mobile",
  "carrier": "T-Mobile",
  "state": "CA",
  "city": "Los Angeles",
  "country": "US",
  "zip": "90001",
  "is_tcpa": false,

}

All these fields are available as variables in your next Zapier step — map them to any field in your CRM, spreadsheet, or database.
