Where can I buy space ID?

Could you elaborate on where and how one can purchase a space ID? I'm particularly interested in understanding the platforms or marketplaces that offer such services. Are there any specific requirements or steps I need to follow to acquire a space ID? Additionally, is there a cost associated with purchasing a space ID, and if so, what are the typical pricing ranges? I'm also curious about the security measures involved in the process to ensure the safety of my investment. Could you provide some guidance in navigating this domain and point me towards reliable sources of information?
