Validate and format phone numbers globally - directly inside your workflows

Clean Dial is a HubSpot workflow app that helps teams verify whether a phone number is callable, enrich it with detailed telecom data, and format it correctly for any region. It saves sales teams from dialing dead numbers, reduces wasted SMS sends, and keeps CRM data clean and consistent.

We built this app after seeing HubSpot users struggle with formatting limitations and the lack of built-in phone number validation. Clean Dial solves these problems natively inside HubSpot - no external tools, no custom code.

Why Clean Dial exists

HubSpot’s native formatting option is limited to international format only, and its workflow actions often assume U.S. number structures. This leads to messy, inconsistent, or unusable data for global teams.

More importantly, HubSpot does not natively validate whether a phone number is actually reachable. Sales and marketing teams were forced to guess, use external APIs, or write custom code to clean their CRM.

Clean Dial fixes this with two workflow actions: Validate Phone Number and Format Phone Number.

Validate Phone Numbers

Check if a number is callable and enrich it with telecom data

The Validate Phone Number action covers 232 countries and supports a default-country fallback when no ISO code is available.

It outputs:

• International format
• National format
• Validity (reachable or not)
• Line status (active or disconnected)
• Line type (mobile, landline, VoIP)
• Carrier information
• Country and timezone
• MCC and MNC data

This gives sales, support, and marketing teams the confidence that the number they are about to use is real and callable.

Free tier: The validator includes 50 lifetime requests, letting you test the action before upgrading.

Format Phone Numbers

The Format Phone Number action standardizes phone numbers for across 245 countries. Users choose their preferred style, ensuring data is always stored consistently.

Clean Dial supports:

• E.164
• International
• National
• Digits-only
• RFC3966

Unlike HubSpot’s native option - which only supports international - Clean Dial lets each team choose the view that best fits their workflow.

Free: This action is completely free and unlimited.
