Hello @Deepverma,
you received good answers here.
The quickest way to know is to go look at your contract, the contract as a chapter called "supplements", and one or more of them will include exactly the information you are looking for, without needing to reach out to SAS.
Proc setinit and Proc product_status, and your sid file will include some information, but, for example, will not include your legal restrictions, such as if a product or full license are limited by named users or on company revenue. Or how many environments. Etc.
When you cannot find this information (your contract holder or finance department should have it), then yes, the best is to reach out to your SAS Account Manager.
