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.

Location or stamping problems

Stamps are location verified. Make sure Location access for Nostos is set to "While Using the App" in iPhone Settings and that Precise Location is available when you are trying to stamp. GPS can be less accurate indoors, underground, or around tall buildings.

"You need to be within 100 m of this place"

Nostos could not verify that you were inside the place's geofence. Confirm that the selected place is correct, move closer to the venue, and try again once your phone has a reliable location fix.

"You already stamped this place"

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

Photo problems

Photos are attached when a stamp is created. If camera access is disabled, enable Camera access for Nostos in iPhone Settings and try again. Uploaded photos are processed before storage and embedded metadata is removed.
