When creating a PlayStation name, also known as a PSN (PlayStation Network) ID, there are several requirements you need to follow:
1. Your PSN ID must be between 3 and 16 characters long.
2. You can use lowercase letters (a-z), numbers (0-9), and underscore (_) in your ID. Special characters and spaces are not allowed.
3. Your ID cannot have any profanity or derogatory terms.
4. Your ID cannot contain the word "Sony" or any of its trademarks.
5. Your ID cannot be identical or similar to someone else's PSN ID.
It's important to choose a PSN ID carefully, as you can only change it once every 6 months. Additionally, your PSN ID is visible to other players you meet online, so make sure it's a name you're comfortable using long-term.
