My general assumption is not that they’re random, but at least that they’re not correlated; in particular that Amazon is not in the habit of handing out, like, account IDs 676363687000 - 676363687999 to a single organization. Even if they did hand out a sequential batch of 1000 account IDs, it would be more likely to be 676363687541 - 676363688540 than a set with a single consistent prefix.
Odds are that an account wildcard match like 676363687* will just match a few hundred entirely random AWS accounts.
- dpedu 3y agoI once was involved in creating two (linked) amazon accounts at the "same" time, and ended up with account IDs of which the first 4 digits are identical.
- jameshart 3y agoA namespace you and only 100 million other accounts share - probably reasonable to just grant access to “1234*”.

It'd still pretty sketchy to design your access control around, but it wouldn't be unrealistic.
