I've couple of AWS Accounts. They all have a unique number. Just curious to know, are those account number random? Or is there any pattern in those number?
Some more details: I'm actually trying to understand when can all the AWS Account number be used?
The documentation says that;
AWS assigns two unique IDs to each AWS account:
- An AWS account ID
- A canonical user ID
An AWS account ID is a 12-digit number, such as 123456789012.
I don't think there is a pattern for this, the only "known" and "important" fact is that they are unique.
I'm actually trying to understand when can all the AWS Account number be used?
Since it is 12 digits number i think there can be (10^11 * 9) different combinations (900.000.000.000) and it is a huge number, so it is fine.
