Lintphone : Validate & Format Phone Numbers in HubSpot Workflows

[DBRAHIM]

Hello HubSpot Community!

I’m excited to introduce Lintphone – a lightweight and powerful tool to validate, clean, and format phone numbers directly inside your HubSpot workflows.

Key Features

• Automatic validation – Instantly checks if a number is real and correctly structured
• Supports 250+ countries and territories
• Multiple formats available:
  • E.164 (e.g., +14155552671)
  • International (e.g., +1 415-555-2671)
  • National (e.g., (415) 555-2671)
  • RFC3966 (e.g., tel:+1-415-555-2671)
• “Call from country” logic – Interprets local-format numbers using your default country
• Smart parsing – Automatically detects and extracts valid phone numbers, even from long multiline text fields. Ideal for processing form comments, notes, or any unstructured data.
• Works as a custom workflow action – No external tools required
• Error tagging – Flag invalid or unknown numbers with custom properties

How It Works

1. Add Lintphone as a custom action in your HubSpot workflow
2. Choose the phone field to clean
3. Optionally define a “call from” country
4. Lintphone formats and validates the number
5. Cleaned number is written back to the contact (same or different field)

---

Use Cases

• Clean phone numbers submitted through forms
• Prepare numbers for WhatsApp, Twilio, or Aircall
• Segment contacts based on phone validity or location
• Fix legacy CRM data with messy formats
• Extract a phone number hidden in a long form message or note field

Thanks for your feedback!

Here’s a screenshot showing the configuration of the custom workflow action, along with the output values returned by the action when it’s executed. This should give you a clearer idea of how it works in practice.

I’ve also included a screenshot of the values returned by the action, as they appear within the workflow. This should help illustrate what data you can work with directly in your automation :

For more detailed information, you can refer to the official documentation: https://lintphone.com/documentation.

Let me know if you’d like to see a full example of it running in a workflow, or if you need anything else!
