Phone Number Validation in Google Forms: Ensure Accuracy and Improve Data Quality

Why Validate? The Importance of Phone Number Validation in Online Forms

Accurate phone data is critical for effective communication, whether you're in marketing, sales, or customer service. Invalid phone numbers lead to wasted resources and hinder your ability to connect with your audience.

By validating phone numbers, you can significantly improve lead quality, reduce bounce rates in outreach campaigns, and ensure that your data is reliable and actionable.

Google Forms How to Set Up Phone Number Validation in

Google Forms provides basic phone number validation capabilities through response validation using regular expressions. Here’s how to set it up:

1. Add a Phone Number Question: Open your Google Form and add a 'Short answer' question, labeling it clearly as 'Phone Number'.

2. Enable Response Validation: Click the three-dot menu (⋮) on the question and select 'Response validation'.

3. Choose Validation Criteria: Select 'Regular expression' from the validation options and set the condition to 'Matches'.

4. Enter a Regex Pattern: Input a regex pattern suitable for your needs. Example: a US phone number: ^\s*(?:\+?(\d{1,3}))?[-. (]*(\d{3})[-. )]*(\d{3})[-. ]*(\d{4})(?: *x(\d+))?\s*$

5. Customize Your Error Message: Create a user-friendly error message, such as 'Please enter a valid 10-digit phone number.'

6. Test Your Form: Preview your form and test various phone number formats to confirm that your validation is working correctly.

Advanced Phone Number Validation Options with Jotform

While Google Forms provides basic validation, Jotform offers advanced features for more robust phone number verification.

Introducing Jotform's SMS Confirmation Widget: This widget sends a verification code directly to the user's phone, confirming the authenticity of each number, and dramatically reducing fake or inactive entries.

Jotform’s widget seamlessly integrates with popular CRM, email marketing, and customer support platforms, including Salesforce, HubSpot, Mailchimp, Slack, and Google Sheets.

Bonus: Using Third-Party APIs: For even greater validation, consider integrating with third-party tools like Twilio Lookup, for features such as carrier detection, real-time number activity status, and accurate formatting for international numbers.

Jotform allows easy integrations with tools like Zapier or direct webhook connections. For example, a Jotform + Twilio integration can offer the following capabilities: Get notified of Jotform submissions with a Twilio SMS message, send SMS notifications for newly signed Jotform documents with Twilio, and more.
