The regexes you found are correct. From the database for org and space name the max length is 255.

Thanks,
Zach

Hi,
 
do you know what makes a valid org, space and service instance name?
 
I was able to find regular expressions for org and space (see below).
For service instance names I was able to find a length restriction.
 
From the database migrations, it is unclear to me to what number of characters it is limited on the database.
 
 
Andreas.
