Prove the package landed at the right door

On time. At the right place. No argument.

A regular photo can be taken anywhere, anytime — so disputes drag on. A Trustamp drop-off photo carries a server-verified time and your real GPS, with a link the customer or platform can verify themselves.

One tap at the doorstep

Fast enough for a real route — strong enough to end a dispute.

Shoot the drop-off

Snap the package at the door. Trustamp stamps a server-verified time and your real GPS — instantly, on-device.

Auto-witnessed

The time and location register with our server (queues offline, uploads on signal) — never the photo. You're already on to the next stop.

Share if challenged

Dispute later? Send the public verify link. Time and place check out independently — no "trust me," no editable caption.

Built for the route

The things that actually matter when you're moving.

Time

Server-verified timestamp

The delivery time comes from our server clock — it can't be argued away as a wrong phone time.

Location

Real GPS, refinable detail

Street is locked to your real location; you can refine the unit/doorplate, transparently noted.

Offline

Works in dead zones

Captured on-device; the witness step queues and uploads when signal returns. No proof lost.

Share

One verify link

Send a single link the customer, platform, or insurer can check — no app install on their side.

Frequently asked

How do I prove I delivered a package to the right address?

Take the drop-off photo in Trustamp. It stamps a server-verified time and your real GPS location onto the credential, so the photo shows exactly when and where the package landed — not just an editable caption you typed in.

What if a customer claims they never received the package?

Share the public verify link for that delivery. It shows the timestamp and location independently — anyone (the customer, the platform, an insurer) can confirm the photo was taken at that door at that time and was not edited afterward.

Does it work when I have no signal or I am moving fast?

Yes. The photo and watermark are generated entirely on-device, and the witness step queues offline and uploads when signal returns. The credential keeps the original capture time, so a dead zone at the doorstep does not cost you the proof.

My GPS is off by a few meters at apartment buildings — is that a problem?

Country, city, and street come from your real GPS and are locked. You can refine the fine detail — the unit or doorplate number — and that refinement is transparently noted on the credential, so it stays honest while still being precise enough to settle a dispute.
