Clean Dial

Clean Dial keeps your HubSpot phone data clean, formatted, and dialable.

It plugs into HubSpot workflows to format phone numbers consistently, run real-time HLR (Home Location Register) lookups to verify whether a number is live and reachable, and surface network intelligence - line type, carrier, portability, disposability - as custom properties on the contact.

What it does

Section titled “What it does”
  • Format Phone Number action. Standardise phone numbers across 245 countries using E.164, international, national, digits-only, or RFC 3966 formats.
  • HLR Lookup action. Verify mobile numbers in real time and return carrier, country, line type, ported/disposable status, and a 0-100 phone confidence score.
  • Custom properties. Clean Dial writes back to a suite of HubSpot contact properties - phone_carrier, phone_line_type, hlr_status, phone_confidence_score, phone_is_ported, phone_is_disposable, phone_syntax_valid, and more - so you can segment, report, and route on phone quality without rewiring your downstream workflows.
  • Bulk HLR Lookup. Verify your entire contact database in one pass instead of waiting for workflow enrollments to trickle through.

When to use it

Section titled “When to use it”

Reach for Clean Dial when phone quality is a material input to your ops - sales dialler routing, SMS sending, call-centre operations, compliance with dial-verification requirements, lead scoring that factors in reachability - and you can’t trust the raw text your contacts typed into forms. It also shines for teams consolidating phone data across imports, M&A lists, and scraped data, where format chaos and dead numbers are the default.

If you just need a cosmetic format pass on a small contact list, the Format Phone Number action alone is enough. If you need real reachability, disposability detection, or carrier-level routing, layer on HLR Lookup.
