Uniqueness of the generated id

Given unique long integers would sqids always create unique id without any collision or overlap ?

[0x3333]

Yes, if you keep the parameters the same.

Thanks. I missed the FAQ where your reply is clearly mentioned. Another concern is from the FAQ decoding random IDs can sometimes produce the same numbers. What are the odds because we are planning to use sqids to stringify our long ids in json output. If two ids produce the same long then it could be a problem.

[0x3333]

If the IDs you generated are using the same parameters, they can't collide, they are unique.

The FAQ is regarding a random generated ID, like brute-force, etc. The algorithm is not cryptographically secure.
