‍Verify 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 live and reachable via HLR Lookups, 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 network verification. Clean Dial solves these problems natively inside HubSpot - no external tools, no custom code.

Why Clean Dial exists

HubSpot’s native formatting is limited, 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 check whether a phone number is actually active on a carrier network. Sales and marketing teams were previously forced to guess, use external APIs, or write custom code to clean their CRM. Clean Dial fixes this with a cost-effective approach using two workflow actions: HLR Lookup and Format Phone Number.

HLR Lookup

Check if a number is live and enrich it with carrier data

‍The HLR Lookup action queries global cellular networks in real-time. It provides granular visibility into the actual status of a SIM card.

It outputs:

• HLR Status: (Live, Dead, Absent, No Coverage)
• Phone Line Type: (Mobile, Landline, VoIP, etc.)
• Phone Carrier: (e.g., Verizon, Vodafone)
• Last HLR Query: Automatic timestamping for data hygiene
• Country and Timezone Data
• MCC and MNC Data

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

Testing Credits: Every new install includes 10 free HLR Lookups so you can test live network connectivity on your own data.

‍

Format Phone Number

The Format Phone Number action standardizes phone numbers across 245 countries. It also triggers the Phone Syntax Valid check to ensure the number is mathematically possible before you spend credits on a network query.

Clean Dial supports five distinct styles:

• Standard Format (E.164)
• International
• National
• Digits-only
• URI Format (RFC3966)

Unlike HubSpot’s native option, Clean Dial lets each team choose the format that best fits their dialer or SMS integration.

Free Tier: This action is completely free and unlimited.
