Proof of who owns it.Not just who has it.
A receipt proves a purchase. It doesn't prove the thing is still yours. OwnVouch keeps the holder and the history of a device — signed by both sides at the moment it changes hands.
Public lookup is free and needs no account.
Before you buy it, ask the registry.
Type the serial from the listing. You'll see whether the device is registered, whether it's flagged lost or stolen, and how many hands it has passed through — never the holder's identity.

Three acts, one record.
Register
Scan the serial and claim the device. Evidence you already have — receipt, box label, a photo of the serial — makes the claim stronger.
Vouch
Verify who you are once. Every claim and handover afterwards carries that weight — without showing your name to anyone looking up the serial.
Hand off
Seller and buyer confirm together. Provenance moves only when both sides have sealed it — and the record follows the device.
A handover is a ceremony, not a form.
Both people confirm the same handover, each on their own phone, each watching the other. Either side can withdraw until the last moment — then both hold to seal, and the record changes hands in one stroke.
Both parties confirmed
Provenance moved from Tomas V. to you on 4 Feb 2026.
More than a serial in a list.
Certificate
A one-page proof of holding, reissued on every handover. Share it as a link.
Passport
Warranty, repairs and proofs, kept in one place for the years you own it.
Lost mode
Report it and the serial shows flagged to anyone who checks the listing.
Claim packet
One export with the paperwork an insurer asks for, assembled before they ask.
Before you ask, ask this.
Is OwnVouch free to use?
Checking a serial is free and needs no account. Registering a device, verifying your identity, and completing handovers are part of the app, which is free right now too — see Terms of Service for how that could change.
Do I need an account to check a serial before buying?
No. Public lookup needs no account and never reveals who currently holds the device — only whether it's registered, its transfer history, and whether it's been flagged lost or stolen.
What does OwnVouch actually verify?
OwnVouch verifies the identity of the people completing a registration or handover, and records what they attest to. It isn't a title registry and can't independently confirm someone has the legal right to sell a device — see Terms of Service.
How does a handover work?
Both people confirm the same handover from their own phone, each watching the other. Either side can back out until the last moment; once both hold to seal, the record changes hands in one stroke.
What happens if a device is wrongly flagged lost or stolen?
You can dispute it with supporting evidence, and we may require additional identity verification from either party before changing a record. A knowingly false report is treated as fraud — see Acceptable Use Policy.
What information does identity verification collect?
Typically a government-issued ID and a liveness check, processed by a third-party verification vendor on our behalf. Full detail in the Identity Verification Disclosure.
Can a record be edited after a handover?
No — terms and transfers are appended to a tamper-evident audit trail rather than overwritten. A cryptographic digest of that trail is periodically anchored on-chain; only hashes are anchored, never personal data.
How do I delete my account and data?
In the app: Settings → Account → Delete account. See Account & Data Deletion for what's removed immediately and what's retained, and for how.
Register the first device in a couple of minutes.
The registry does the remembering.
