NumNum performs CNAM and CallerID lookups directly — no carrier queries, no passthrough surprises. Use the portal, hit the API, and let our two-level cache drop per-lookup cost to a tenth of a cent.
Most of our customers never write a line of code. The portal handles one-off lookups, bulk CSV, API keys, spend, and the full audit log — all from a single dashboard.
We run the lookups ourselves — not through the carriers. Faster, cheaper, and your number activity stays out of anyone else's logs.
We perform lookups ourselves against our own data sources. No carrier queries, no per-number carrier fees, no leaking your number activity upstream.
L1 edge cache + L2 durable store with stale-while-revalidate. L2 hits are 0.1¢. Typical hit rates land 50–70%.
Query rate, hit rate, stale refreshes, refresh failures, cache age. Filter by key, user, or date — down to the minute.
Run lookups interactively in the portal, in bulk via CSV, or programmatically through a single REST endpoint with SDKs in Node and Python. Same data, same cache, same billing. Most customers never touch the API; the ones who do ship in an afternoon.
Every lookup — number, source, cache tier, cost, user, timestamp — stored and searchable. Never guess what was charged.
Five free lookups to kick the tires. $9/month when you're ready for the rest.
Email + password. Get 5 free lookups to try the portal, run a real query, and see the data.
Paste a number into the search bar at the top of every page. Results, carrier, cache tier, cost — all on screen in under 200ms.

Over 1M lookups/month? We'll write you a custom deal →
We perform the lookups ourselves — we're not a passthrough to the carriers. That means you pay our price (not theirs), results come back faster, and your number activity doesn't get logged by third parties upstream.
Full portal access and 5 free lookups, one-time. After that you'll need the $9/month plan to keep looking things up. No credit card to sign up.
L1 is an in-memory edge cache (seconds to minutes). L2 is a durable store with a configurable TTL — default 90 days — and stale-while-revalidate. A stale L2 hit serves instantly and triggers a background refresh. L1 and L2 hits are 0.1¢; fresh misses are 0.2¢.
No. Most of our customers never touch the API — the portal handles one-off lookups, bulk CSV uploads, stats, keys, and billing. The API is there when you want it, with the same keys and billing.
Yes — that's how caching works. They're encrypted at rest and scoped to your account. You can purge any record or all records at any time from the portal. Retention is configurable down to zero (passthrough mode).
Yes. Create a key per customer, set quotas, and the portal rolls up revenue attribution in the Statistics view. Many of our customers are telecoms reselling CallerID to their own downstream clients.
Free signup. 5 free lookups. $9/month when you're hooked.
