Game top-ups by UID: how they work and how to get the ID and server right
How an ID top-up differs from a code, where players find their UID and Zone ID, and why checking before payment saves money.
A top-up by UID (player ID) is the easiest way for a buyer to get in-game currency: nothing to redeem, the currency just arrives. For the seller it means fewer questions and fewer refunds, provided the ID is right.
How an ID top-up differs from a code
- A code is entered by the buyer on a website or in the game. It can be resold if the buyer changes their mind.
- An ID top-up is credited straight to the account. The buyer only gives their ID, sometimes with a server. It can’t be reversed, so the ID must be right.
Where players find their ID
- PUBG Mobile: player profile, the numeric ID under the nickname.
- Mobile Legends: profile shows “ID (Zone ID)”, such as 12345678 (1234). The number in brackets is the Zone ID, and the top-up fails without it.
- Genshin Impact, Honkai: Star Rail, Zenless Zone Zero: the UID is in a corner of the screen; the server is needed too: America, Europe, Asia or TW/HK/MO.
- Wuthering Waves: the UID in a corner of the screen and the server picked at login.
- Honor of Kings, Delta Force, Blood Strike, Arena Breakout, Call of Duty: Mobile: the ID in the player profile.
Why checking before payment matters
One typo in the ID and the currency goes to someone else, with almost no way back. That’s why, when you buy in the PacketUP HUB dashboard, the ID is checked before payment and the nickname is shown: if it’s the wrong player, you see it in advance.
Tip: ask buyers for a screenshot of their profile, or to copy the ID with the in-game button instead of retyping it.
Servers and regions
In some games accounts live on separate servers and a top-up goes to one. Some games have separate products per region, such as Mobile Legends GLOBAL and Mobile Legends RU. Ask the buyer where their account was created.
How fast the currency arrives
Usually within a minute or two after payment; each product card shows its delivery time. Through the API the result is easiest to get by webhook; see the API guide.
