Is this number a verified human?
One question, one answer. Humber tells you whether a real person stood behind a phone number — and nothing else about them.
5 lookups a day, for personal use. Humber never tells you who a number belongs to — only whether a person stood behind it.
How it works
A person proves the number is theirs
We text a one-time code. Passing it proves control of the line — not identity, not a name.
They pay $5 a year
Trivial for one person. Ruinous at the scale a spam operation would need. That asymmetry is the entire economic idea.
Anyone can check the number
The answer is a single bit: verified, or nothing. No directory, no list, no export, and no way to ask who a number belongs to.
We never hold a list of your phone number
A registry of verified phone numbers would be exactly the thing you would not want leaked — a directory of confirmed, reachable, real people. So we built it so that directory cannot exist.
Each number is turned into a keyed one-way fingerprint before anything is written down. The fingerprint cannot be run backwards, and the key that makes it is held separately, so stealing the whole database still buys an attacker nothing — there is nothing in it to read.
The practical consequence: to check a number, you have to already know it. Someone who does not have your number learns nothing from Humber, ever.
Make your own number answer “verified human”
$5 a year, renewing automatically until you cancel. Prove the number is yours and anyone who checks it gets a yes. Cancel any time by revoking it — that stops the billing and switches your number’s answer off.
