How can you verify that your Mount Rinjani trekking permit has actually been purchased?

Ask your operator for the issued e-ticket with its QR code, then check the names, passport numbers, trekking date, and entry and exit gates shown on that ticket against your own documents. A paid e-Rinjani ticket can be retrieved through the official account or the registration email, and its QR code can be displayed in the app, downloaded, or printed for check-in at the gate. That ticket is the proof of purchase, not a screenshot of a booking form.

The status of the booking matters as much as its existence. The park’s ticket history distinguishes paid tickets from entries that are awaiting payment, cancelled, or expired, so a reservation that was never paid looks like a booking but will not get you through check-in. Ask the operator to show the paid status inside the official booking account, since an invoice, a bank transfer receipt, or an unpaid reservation screenshot does not demonstrate that the park issued a valid permit.

Keep the verification practical. The official system runs on the park’s rinjaninationalpark.id domain, so treat anything else claiming to be a permit checker with suspicion, and do not rely on lookalike websites to validate a booking code. If the operator booked on your behalf, ask for the booking identifier as well as the ticket, so the park office can trace the transaction if anything looks wrong at the gate.

One detail that saves trekkers regularly: keep an offline copy of every QR ticket. Mountain reception cannot be assumed, and there are dead zones in the forests, ravines, and parts of the crater, so a ticket that only lives in your email can become unreachable exactly when the gate staff ask for it. Save the QR image to your phone gallery and carry a printed copy.

We send every guest their issued ticket before the trek starts and walk through this exact checklist: paid status, exact named guests, passport number match, registered date, authorized entry and exit, and an offline copy of the QR code. If any item is missing, we fix it in town the day before, because permit problems are far easier to solve with signal than at a trailhead gate.
