A change means the set of open dates for Core Zone actually shifted between two scans: a date opened, closed, or quota moved. Counts update continuously.
How long openings last
70% of the openings the scanner caught on Core Zone were gone within 10 minutes.
Measured across 33 openings that did not reopen, as of August 2026.
Each figure comes from our own scans, comparing when an opening appeared with when it was gone. Permits we cannot measure precisely enough are left out rather than estimated.

How cancellation tracking works
Sold out almost never means gone. People cancel Core Zone trips for weather, injuries, and schedule changes, and those dates go straight back to the booking system without any announcement.
PermitSnag checks Core Zone availability around the clock, compares every scan against the last known state, and alerts watchers only when the open dates actually change. No refresh-tab-and-pray, no false alarms from unchanged listings.
Core Zone availability questions
How do I get a Core Zone permit after it sells out?
Cancellations. Booked Core Zone permits that get cancelled return to the reservation system, usually with no announcement. PermitSnag scans continuously and alerts you the moment a date you want opens up.
How often do Core Zone permits become available?
In the recent tracking window our scanner detected 210 availability changes for Core Zone and sent 55 alerts to watchers in the last 30 days. Cancellations cluster around fee deadlines and weather changes.
How fast are Core Zone availability alerts?
Paid plans are scanned about every minute and alerts go out within seconds of a detected opening, by push notification, SMS, and email. Free accounts are scanned hourly.
Can I still get a Core Zone permit if I lost the lottery?
Usually yes. Winners cancel or skip payment deadlines, and those dates return to the booking system. Tracking Core Zone for cancellations is the standard fallback after a lottery loss.
