Numbers Online Plans Pricing

Public lookups are free forever with no account. The API has a free, unbilled, rate-limited tier on a self-service key (no card, no sales call), a prepaid standard tier billed per dip against a balance topped up in $5–$500 Stripe Checkout increments, and a custom enterprise tier. Separately, number VERIFICATION is what raises pooled API limits: personal is a one-time $9 (a trust badge — adds no API capacity), business is $29/year auto-renewing per number (+60/min, +2,000/day lookups, +100/day reports each). Prices in USD, exclusive of taxes.

Free API tier (Public lookup) free

Every endpoint works on the free tier, unbilled and rate-limited; no card.

Personal · Verified one-time

Verify ownership of a personal number; the public sees only "verified & online" plus its risk score. A trust badge, not API capacity — same free API pool.

Business · Verified subscription

Business identity verification with a public profile; raises the account's pooled API limits and unlocks the accountable report lane and outbound pre-call enrollment.

Standard (prepaid) usage-based

Prepaid credit ($5 minimum to $500 per Stripe Checkout) billed per dip against the balance; 402 insufficient_balance when exhausted.
