Counting dropzones is the easy part. The hard part is telling a reader which of the facts in a listing is still true, where each one came from, and what happens when one of them is wrong. Most directories, including the largest, answer none of those three.
The four things that matter
Coverage. How many dropzones, in how many countries. This is the only measure most directories publish about themselves, and it is the least useful one, because a record that is wrong still counts.
Provenance. Can you tell where a given fact came from - the operator, a scrape, or someone's memory. A phone number with no source is indistinguishable from a phone number that was confirmed last week.
A checked-on date, per record. Not a site-wide "last updated". Dropzones change aircraft, prices, hours and ownership, and a listing that was right in 2019 reads exactly like one that was right yesterday.
A correction loop. What a reader does when they find an error, and whether anyone can see that the correction happened. Without this, a directory decays quietly and its age is invisible.
What the field looks like
The reference used to be dropzone.com, which carried a reported 100,000-plus users and over a
thousand operator-maintained listings with reviews. Its domain now redirects to an unrelated
commercial page, apex and deep forum paths alike, verified by direct fetch on 2026-09-18. The sport's
largest accumulated record sat on one lapsing registration, and that is the strongest available
argument for caring where a directory's facts live.
DZSpotter prints 274 dropzones across 29 countries on its own directory page, read 2026-09-18. It is
free and has no paid tier visible. DropzoneFinder, Dropzone Atlas and skydivingsource.com also
exist; we have not sized them, so we make no claim about them.
Google has by far the widest coverage of any of them and satisfies none of the other three. There is no way to ask a search result where a fact came from or when it was last confirmed.
Where ExtrmSport sits
The limit first, because it is the one that decides how much to trust a listing: accuracy here depends on operators claiming their own listings, and that has not happened yet. For any single dropzone, Google may currently hold a more accurate phone number or price than we do. Records are flagged where the data is unverified, and anyone can submit a correction.
On coverage, the directory holds more than 1,000 dropzone records across more than 80 countries - more than five times the dropzone records of the largest free directory we could find. That figure is a floor rather than a count, and it is raised only when the underlying set clears the next one.
Coverage is not the thing to judge us on. The correction loop is, and it is only as good as the number of operators who use it.
This page does not rank the directories above, and it is not a recommendation to use any of them. It sets out the four questions worth asking of whichever one you rely on, including ours.
