Forms and Surveys SMS Verification

Validate phone numbers inside forms and surveys with a one-time passcode (OTP). Improve data quality, reduce spam, and clearly identify which submissions included a verified phone number.

Improving Form Quality by Verifying Real Phone Numbers

Forms and surveys often collect incorrect, fake, or mistyped phone numbers, making follow-up communication unreliable and reducing the quality of lead data inside the CRM.

SMS Verification in BizStackPro uses one-time passcodes (OTP) to confirm that a submitted phone number is valid before marking it as verified inside form and survey submissions.

Without phone verification, businesses can waste time on failed outreach, inaccurate contact records, lower-quality leads, and unnecessary automation activity tied to invalid numbers.

This guide explains how SMS Verification works in forms and surveys, how verified phone status appears in submissions, how to enable or disable the feature, and how to manage verification-related costs and workflows inside BizStackPro.

Before enabling OTP verification on your forms, it helps to understand how the verification flow and verified status tracking work inside BizStackPro.

Overview

SMS Verification for Forms and Surveys lets participants confirm their phone number during submission using a one-time verification code (OTP) sent via SMS. This helps prevent typos, reduces fake numbers, and improves the reliability of your contact data.

Once verified, submissions include a dedicated Phone Verified field—so you can quickly filter for verified contacts.

Best use: Enable verification on lead capture, applications, onboarding, and any form where accurate phone numbers are critical for follow-up.

Benefits of SMS Verification

  • Data integrity: fewer typos and invalid/fake numbers.
  • Lower spam: OTP verification discourages bots and low-quality submissions.
  • Clear status: submissions display Phone Verified = Yes when successful.
  • Better automation: prioritize or segment follow-ups using verified phone data.

How SMS Verification works

  1. Open the Form/Survey builder: Go to Sites and select Forms or Surveys, then create a new asset or edit an existing one.
  2. Add or select a phone field: Participants enter their phone number in the designated phone field.
  3. Click “Verify Phone”: After a valid number is entered, a Verify Phone button appears.
  4. OTP is sent via SMS: The participant receives a one-time code on that phone number.
  5. Enter the OTP code: If the code matches, the phone number is marked as verified.

If it fails: If the code is missing or incorrect, the number won’t be verified. The participant can request a new code and try again.

Where verification appears in submissions

Each submission includes a Phone Verified field. When a participant completes OTP verification successfully, the value is marked as Yes.

Workflow idea: Trigger follow-up SMS only when Phone Verified = Yes (or use it as a filter/segment step before outreach).

Enable or disable SMS Verification

SMS Verification can be toggled per form or per survey, so you can apply it only where it matters most.

  1. Go to Sites → Forms/Surveys.
  2. Create or edit the form/survey.
  3. Select the phone field (or its settings panel).
  4. Toggle SMS Verification on/off (label may vary slightly).
  5. Save and publish.

Billing and OTP considerations

OTP messages sent during the verification flow are billed separately as SMS usage. If a form receives high traffic, plan for the extra verification message volume in your messaging budget.

Tip: Use SMS Verification on high-intent forms (applications, booking requests, onboarding), and keep it off for low-stakes surveys to control costs.

Best practices

  • Set expectations: add a short note near the phone field (“We’ll text a one-time code to verify your number”).
  • Use verified status in automations: prioritize follow-up when Phone Verified = Yes.
  • Monitor usage: keep an eye on OTP volume and costs for high-traffic forms.
  • Reduce friction: keep the verification step close to the phone field and the CTA clear (“Verify Phone”).

Collect more reliable phone numbers

OTP verification helps reduce fake entries and improves the quality of your follow-ups—especially for lead capture and onboarding.
