Sales · Compliance · List hygiene
The same API powers very different jobs. Whether you're scrubbing TCPA litigators before an SMS campaign, validating identity at signup, cleaning a CRM list, or scoring sales leads, the best mix of fields and add-ons depends on the use case. Pick yours below to see the recipe.
Professional TCPA plaintiffs file thousands of suits a year. One name in your list can cost more than your year of marketing.
Enable litigatorFilter on every lookup to get the litigator flag, type, and on-record name to route them out before you send.
Read the use case →State DNC registries are enforced separately from the federal list, and most teams scrub them late, rarely, or not at all.
Enable the free dncOther flag to check state registries (40 states) and our national complainer list on every lookup, with an explicit coverage indicator.
Read the use case →Fraudsters use VoIP and recently-ported numbers to bypass identity checks.
Combine nanpType, dipCarrierType, dipPorted, dipCarrierSubType, and ipResult to score a number's legitimacy at signup.
Read the use case →Lists drift. Numbers get deactivated, reassigned, and re-ported. Email-style validation can't see any of this.
Use deliverable, reason, deactivationDate, and dipCarrier to rebuild a clean, current list on a schedule.
Read the use case →Bad leads waste prospecting time. Mobile vs landline changes the cadence: call or text first?
Use nanpType, dipCarrier, deliverable, and timezone signals to score leads and assign the right channel.
Read the use case →Both sides of the lead-gen trade get burned by bad numbers: sellers lose acceptance, buyers pay for trash, and one litigator on the list triggers a TCPA claim.
Validate at form-submit, attach metadata to the ping, let buyers re-validate on the post, with a litigator filter on every lookup.
