Fix: PSO2 Phantasy Star Online Error 602

Phantasy Star Online 2 is a Sega-published successor to both Phantasy Star Online and Phantasy Star Universe. It’s an MMORPG game, and it was initially released in Japan in 2012. Being free to download and play, it became very popular.

It wasn’t popular only in Japan, however. Since it had a very interesting style of play, it also became popular all over the world, with players resorting to VPN and proxies to be able to play. At one point, there was a plan for an international launch, with SEGA allegedly having an English version ready for launch. That version was eventually canceled, leaving a lot of players frustrated.

Even though the game had a stellar reputation, it’s not to say that it is error-free. There are a lot of error codes that hit players at one point or another, but one of the most common ones was Error 602. Since, regardless of location, you’re playing the Japanese version, the error message is extremely difficult to understand. If you’re an international player who doesn’t know Japanese, you can be stuck here for a while. Fortunately, there are players who have found a translation and saw what the issue is caused by.

What causes the PSO2 Error 602?

As simple as it sounds, the problem lies in capitalization. Even though you might’ve made your SEGA ID with some capital letters, the game’s system doesn’t accept them. Therefore, when you try to log on with your SEGA ID and enter those capital letters, the game gives you that error and refuses to log you on. Worst of all? Unless you know Japanese, you won’t know what the issue is. This is actually a simple thing to fix. Why SEGA has done nothing to solve the problem is beyond us. It’s very frustrating, especially for international players.

Log in with your SEGA ID all in lowercase characters

Fortunately, this is a fairly simple problem. The solution is just as simple, too All that you need to do is remove any uppercase characters, even if your SEGA ID does have them. When you’re logging in, make sure to write your entire SEGA ID with only lowercase letters.
