Trackable prefixes help Geotrackable decide whether a code belongs here, belongs on another live site, or should use bring your own because the original system no longer handles it.
Geotrackable is happy to help people understand where a code belongs, but it should not silently re-home live third-party trackables that already have an active origin system.
If the code belongs to a live outside system, Geotrackable blocks bring-your-own registration for that prefix and points you back to the origin site instead.
When a code came from an older private system or a retired service, Geotrackable can still adopt that physical item through the single-trackable bring-your-own flow.
Before Geotrackable tells you that a prefix belongs somewhere else, it still checks its own database so older items created before the tighter prefix rules are not sent away by mistake.
GT is the Geotrackable system-issued trackable prefix. Use the normal Geotrackable create flow for new items instead of typing a GT code into bring your own.
Open Geotrackable.comLN is the LocationNotes system-issued trackable prefix. Those items should stay on LocationNotes.com unless you are only browsing the shared account system here.
Open LocationNotes.comTB is the official Geocaching.com public trackable reference prefix used by Travel Bugs and many Geocaching.com-backed trackables. GC belongs to Geocaching.com too, but it is reserved for geocache listings rather than trackables, so Geotrackable catches GC lookups and points them back to Geocaching.com.
Open Geocaching.comGK identifies GeoKrety trackables. GeoKrety is still active, so Geotrackable sends those codes back to GeoKrety.org instead of adopting them here.
Open GeoKrety.orgBring your own is meant for a physical item that already has a real code and still needs a home because the original service is gone, private, or otherwise not handling the workflow anymore.
That is why Geotrackable blocks the still-active prefixes above but still lets older private-system items come in through the single-trackable create flow.
Create a Single TrackableA prefix is a strong hint, but it is not magic. Some manufacturers and apps use additional shorthand that still routes back to another system, and some older custom items never had one universal public pattern.
That is why Geotrackable documents the reliable active prefixes here, treats GC as a common wrong-kind-of-code catch, and leaves unusual retired cases to the bring-your-own workflow instead of pretending every prefix on the internet has one perfect rule.
That keeps live third-party items on their origin platform, keeps Geotrackable focused on Geotrackable-owned or properly adopted items, and gives older retired-system tags a clear bring-your-own path instead of a dead end.
