What the Endpoint Returns

The response is intentionally compact and returns only the fields a CRM or dialing workflow can act on quickly.

Line & Carrier Data

Get normalized phone number, line type, carrier, and the most recent last-seen date returned by the data source.

DNC/TCPA Signals

Receive boolean DNC and TCPA flags plus a state_dnc array when state-level codes are returned.

Associated Persons

Return light person context — name, age, city, and state — without exposing emails, address history, or additional phones.

Different From Reverse Phone Append

Reverse phone append is for building a broader contact profile from a phone number. Phone Intelligence is for reviewing phone and compliance signals before the number enters your workflow.

  • Use Phone Verification for carrier, line type, last-seen, DNC/TCPA, state DNC, and contactability flags.
  • Use Reverse Phone Append when you need names, emails, addresses, and broader contact enrichment.
  • Use DNC Lookup when you only need a dedicated suppression check without enrichment context.

Built for Real-Time CRM Decisions

Check phones before dialing, importing records, assigning leads, or deciding whether a number should stay in a campaign. Returned compliance fields are informational and should be combined with your own consent records, policies, and legal review.
