How to Use Smart Columns to Validate Any Phone Number Stored in Your monday.com Phone Column

Automatically ensure accurate phone data and eliminate invalid entries with Smart Columns.

Incorrect or inconsistent phone numbers on monday.com boards can lead to communication errors, delays, and wasted follow-ups. Without a reliable way to validate phone data, teams often spend time correcting typos or chasing down clients.

Why It Matters

Validating phone numbers at the source means:

  • Fewer customer communication failures
  • Better contact data hygiene
  • Less time spent on manual cleanup
  • Higher team productivity

When phone number accuracy is critical—like in sales, customer service, or logistics—this Smart Column feature is a game changer.

Real-World Use Cases

  • Sales teams: Validate lead phone numbers before triggering an outreach workflow
  • Customer support: Ensure valid numbers for escalations and callbacks
  • HR onboarding: Confirm mobile numbers before sending documents or logins
  • Event planning: Avoid failed confirmations for RSVP follow-ups

What This Smart Column Does

The Phone Number Verification column checks the validity of data stored in your monday.com phone columns. It can be triggered by status changes, new item creation, or movement across groups—ensuring that all contact information is accurate and formatted correctly.
