What this page is, and what it is not. On 2026-07-26 we sat at the official Gift Code Center and fed it deliberately wrong combinations of Account ID, Empire ID and code to find out what each refusal actually means. Every finding below is ours, from that session — nothing here is copied from another site, because as far as we can tell no other site has it.
One honest caveat up front: the account we tested on runs the Korean client, so the wording we saw on screen was Korean. The error codes underneath are language-independent, and those are the part that matters. We describe each message by what it means rather than pretending to quote English text we have not seen.
| What the page refuses with | What it actually means | What to do |
|---|---|---|
| It says your Account ID or Empire ID looks wrong | The server could not find the account at all | You almost certainly swapped the two IDs — see below |
| It says the code does not exist | The code is fake, mistyped, or already withdrawn | Stop trying. The code is dead, not your account |
| It says your account level does not meet the conditions | The code is alive. Your account is what failed | Raise your Town Center — not your Lord level |
1. "We can't find that account" — you swapped the IDs
Account ID and Empire ID are different numbers and they live one screen apart, which is why this is the most common failure by a distance. Tap the profile icon at the top left for your Account ID; go through to the Lord screen behind it for your Empire ID. The Account ID is the long one. The Empire ID is your empire's number and can be as short as one or two digits — if you are typing something short into the Account ID box, that is your bug.
2. "That code doesn't exist" — the code is the problem, not you
We confirmed this by typing pure gibberish, which produced exactly this refusal. So when a code you found elsewhere returns it, the site you got it from has simply left an expired code up. Two things worth knowing: codes are case sensitive, and paste beats typing.
3. "Your level doesn't qualify" — this is good news
This one is worth understanding properly, because it is the only refusal that confirms the code is real. A dead code never gets this far — it is rejected at step 2. So if you see this, stop hunting for a better code. The code works. You do not qualify yet.
The trap in message 3: it is not your account level
The message talks about account level. The server is not checking your account level. We read the raw response the server sends back to the browser, and the refusal carries the error name STOVE_LV with the code 40006.
Stove is Century Games' internal variable name for the main city building — in Whiteout Survival that building literally is the Furnace, and the name has evidently been carried across the codebase. In Lordrush the building in that slot is the Town Center. Which means, in practice: grinding Lord XP will not fix this. Quests and hunting raise your Lord level and the code will keep bouncing. Push the Town Center.
This error is documented nowhere. It is not in the publisher's announcements, not on the code-list fan sites, and not in the third-party write-ups that reverse-engineered Century Games' redemption API and tabulated its responses (SUCCESS, USED, TIMEOUT RETRY, CAPTCHA CHECK ERROR and the rest) — STOVE_LV and 40006 appear in none of them. We found it by submitting the request and opening the response.
The threshold is Town Center Lv. 6
We measured it on a single account across one upgrade, which is the only way to measure it cleanly. At Town Center Lv. 5 the server refused the code with 40006. We upgraded that one building to Lv. 6, changed nothing else, and resubmitted the identical code: SUCCESS (20000), and the page confirmed the rewards were on their way to in-game mail.
So Lv. 6 is the gate. If you are stuck at Lv. 5, the code is not the problem — one upgrade is. Century Games has never published this number and we have not found it anywhere else; it is ours, from one account, and we will say so if we ever find it behaves differently.
Success does not show you the rewards
A successful redemption shows a confirmation and nothing else. The items go to your in-game mail. Check that mail — people conclude the code failed because the screen stayed empty.
The working codes and their measured rewards are on the main Lordrush page.
Measured by us at the official Gift Code Center on 2026-07-26, re-checked 2026-07-30. Screen wording was observed on a Korean-language client; error codes are language-independent.
