Built for compliance-first calling teams

Know before you dial. Screen every number against the DNC registry, instantly.

Single-number lookups, bulk CSV scrubbing, and a REST API for your dialer or CRM — all on infrastructure designed for fast, indexed phone-number checks, not slow spreadsheet scans.

A "no match" result reflects only the dataset loaded on the platform — it is not a legal guarantee a number is safe to call. Read our compliance approach.

How it works

One dataset. Three ways to check it.

Whichever way your team works — a quick manual check, a list to clean before a campaign, or a live feed from your dialer — it hits the same indexed dataset and the same compliance disclaimer.

Single Search

Paste in a number, get a clear DNC_MATCH, NO_MATCH_FOUND, UNABLE_TO_VERIFY, or INVALID_NUMBER result with the dataset version and timestamp it was checked against.

Bulk Scrubbing

Upload a CSV or TXT list. We detect the phone column, normalize and de-duplicate numbers, and hand you back a results file — without freezing the app while it runs.

REST API

Wire your CRM or dialer directly into /api/v1/scrub with a scoped API key, per-minute rate limits, and a monthly allowance you control per customer.

Built for speed

Phone lookups don't scan a table — they hit an index.

The DNC dataset is stored with the phone number itself as the lookup key, so checking a number stays fast whether the dataset has thousands of records or millions.

  • Indexed, constant-time lookups
  • Bulk uploads run in the background — the app stays responsive
  • Dataset replacements swap in atomically, with zero downtime

Multi-tenant by design

Every company's data stays their own

Each customer is a fully isolated tenant — their searches, files, API keys, billing, and team are never visible to anyone else on the platform, enforced at the database layer, not just hidden in the UI.

Team management

Add teammates with granular, per-user permissions your admin controls.

Plan-based limits

Search, bulk, and API allowances are set per plan or overridden per customer.

Audit logging

Every admin action, subscription change, and key event is recorded.

Usage visibility

See exactly how much of each allowance you've used, in real time.
