I have an 8-digit ID :)

Gumi started with 8-digit IDs, but the game was getting super popular and the player base was growing so fast that Gumi increased the length to accommodate that growth. So new players are now getting 8-10 digit player IDs. 8-digit IDs are still in use, as is your case. Hope that helps!
