Hi, would like to ask, is there possible create own id for each cpt without following the current wordpres post id? Said if want to collect cpt entry from frontend form starting with "Prefix-001, Prefix-002", and so on?
No, it's not encouraging to change the post ID of WordPress. The post ID is auto-increment and unique for each post so you do not need to change it. You can create a custom field and add any field type to the posts if you want to distinguish them.
