Genshin Impact Top-Up Guide: The UID Method Explained (2026)

Every 5-star pull in Genshin Impact ultimately runs on Genesis Crystals — and the in-app store is the most expensive way to get them. The UID top-up method credits the exact same crystals to your account at a real discount, without ever touching your login. Here's how it works and how to do it safely.
What the UID method actually is
Your UID is the public number on your in-game profile — the same one friends use to add you. With UID top-up, that's all a seller needs. They credit crystals to your UID through official recharge channels, and they appear in your account within minutes. You never share a password, an email, or a login code.
Why marketplace top-ups are cheaper
HoYoverse prices crystals differently across regions. Top-up sellers source through lower-priced regions and pass the difference on to you. The crystals themselves are identical and credited through official channels — you're paying less for exactly the same thing.
Check your server region first
America, Europe, Asia and TW/HK/MO are separate servers, each with its own UID. Crystals go to the UID exactly as entered, so confirm you're giving the UID for the server you actually play on.
How to top up safely, step by step
- Copy your UID from your in-game profile and double-check every digit.
- Pick a listing that matches your server region.
- Pay through the marketplace so escrow holds your money until the crystals land.
- Follow the seller's instructions and wait — most top-ups complete within 5–30 minutes.
- Confirm the order only after you see the crystals in your account.

Frequently Asked Questions
Is UID top-up safe for my Genshin account?
Yes — the top-up goes through official recharge channels using only your public UID. Your login stays private, and marketplace escrow protects your payment until the crystals arrive.
How long does a top-up take?
Most complete within 5–30 minutes. You'll see the crystals appear in your in-game balance or mailbox; confirm the order only after they land.
Why is it cheaper than buying crystals in-app?
Regional pricing differences. Sellers purchase through lower-priced regions and pass the savings on. The crystals are identical and delivered through official channels.
