Sign-in or verification problems

Make sure you entered the correct email address and check your spam or junk folder for the Nostos verification email. If a code expires, request a new one. If you still cannot sign in, contact us at support@nostospassport.com.

Visit verification

Location is optional. A Now stamp can show as verified when Nostos can confirm that your device is close enough to the selected place at the time you stamp it. If location access is off, unavailable, or you are outside the venue's verification radius, you can still create the stamp and it will simply be unverified. Past stamps are always unverified.

If a visit you expected to be verified is not, confirm that Location access for Nostos is set to "While Using the App" and that Precise Location is available. GPS can be less accurate indoors, underground, or around tall buildings.

Past stamps and visit dates

You can add a Past stamp for a visit from the previous year, but not for a future date. You can also edit a stamp's visit date. Changing the calendar day on a verified visit removes its verification because Nostos only verified the original visit day.

"You already stamped this place"

You can create a new stamp at the same place once every 15 minutes, with a maximum of 20 new stamps per hour across places.

Photo problems

You can take photos through Nostos or choose them from your Photo Library, and you can add or remove photos after a stamp is created up to the six-photo limit. Nostos verifies visits, not individual photos. Photos taken through Nostos receive a small Nostos watermark. Uploaded photos are processed before storage and embedded metadata is removed.
