Most top-up failures are caused by an incorrect player ID. Before you order, copy your ID from inside the game — never from memory.
Mobile Legends
Open your profile in the top-left corner. Your ID is the number under your name, with the zone ID in parentheses — enter both.
PUBG Mobile
Tap your avatar → your numeric ID appears under your nickname.
Genshin Impact
Your 9-digit UID sits at the bottom-right of the main screen. Choose the correct server region too.
Free Fire
Profile → the ID is listed under your basic info.
Tip: paste the ID into your order instead of typing it, and re-check the first and last digits.
