Where to Activate a PC Game Key: Epic, EA App, Ubisoft Connect, Battle.net, GOG, Rockstar & Microsoft Store (2026)

Almost every guide to activating a PC game key assumes the key is a Steam key. Plenty of them are not. Buy a Ubisoft title, an EA sports game, a Blizzard release, a Rockstar game or a store exclusive on Epic, and the code you receive has to go into that publisher’s own launcher — Steam will simply reject it, usually with a message generic enough that people assume they have been sold a dud. Nothing is wrong with the key. It is just standing at the wrong door.

This guide covers the seven places a PC key can actually be redeemed in 2026. For each one you get the route through the desktop client, the browser fallback for when the client is misbehaving, and the specific menu wording to look for — because in every case the option is tucked behind an avatar or a profile icon rather than sitting anywhere obvious. Every path below was checked against the platform’s own help documentation in August 2026.

First, work out which store the key belongs to

This is the step people skip, and it causes most of the confusion. A key is issued for exactly one platform, and the platform is decided by the publisher, not by you. Two copies of the same game bought from two sellers can activate in two completely different launchers.

Do not try to identify the platform from the shape of the code. Code lengths overlap heavily between stores, and guessing sends people down a chain of failed attempts that can trip the rate limit on the very launcher they needed. The answer is written down in three more reliable places:

• The product page you bought from — a legitimate listing always names the activation platform, usually in the title or a “Platform” field near the price.
• The delivery email or order page, which normally repeats the platform next to the code itself.
• The game’s publisher — a title published by Ubisoft, EA, Blizzard or Rockstar is very likely to use that publisher’s launcher, even when the same game is also sold on Steam.

The redemption cheat sheet

The rest of this section walks each one through properly, including the confirmation screens that are easy to click past.

Epic Games Store

1. Open the Epic Games Launcher and sign in
   Use the Epic account that should own the game. If you have more than one — say, one linked to a console and one to your PC — check which is loaded before going further.
2. Click your name in the upper-right corner
   This opens the account dropdown. It is the same menu that holds your library and account settings, so it is easy to overlook.
3. Choose “Redeem Code”
   A single-field dialog opens. Paste the code rather than typing it where you can — Epic accepts pasted codes with their dashes intact.
4. Click “Redeem”
   A success message confirms the code was accepted, and the game appears in your library ready to install.

EA app

1. Launch the EA app and sign in
   The EA app replaced Origin, so older guides pointing at an Origin menu no longer match what is on screen.
2. Click your profile avatar, top-right
   Then select “Redeem Code” from the dropdown.
3. Enter the 25-character product code
   EA product codes run to 25 characters. Type them exactly as issued if pasting fails.
4. Confirm
   The entitlement is added to your EA account. This same flow handles full games, in-game content and EA Play memberships.

EA offers two browser routes as well: a dedicated redemption page at ea.com/redeem, and a “Redeem Product Code” tab inside your EA account settings. Both apply the code to whichever EA account is signed in, so check the account name on screen before submitting.

Ubisoft Connect

1. Open Ubisoft Connect PC and sign in
   Ubisoft keys activate through the desktop client. There is no equivalent browser redemption page, so install it if you have not already.
2. Click your profile icon in the top-LEFT corner
   Ubisoft is the odd one out here — every other launcher in this guide puts the account menu on the right.
3. Select “Key Activation”
   Some client versions label this “Key/Code Activation”. Both open the same dialog.
4. Enter the key and select “Activate”
   The game is bound to the Ubisoft account you are signed in on, and appears in your library to download.

Battle.net

1. Open the Battle.net app and sign in
   Confirm you are on the Blizzard account that should receive the game — Blizzard applies codes immediately, with no undo.
2. Click your username, top-right
   Then select “Redeem a Code” from the dropdown.
3. Enter the code and click “Redeem”
   Games, expansions and in-game items all go through this same field.
4. Check your library or in-game inventory
   Game licences show up in the Battle.net library; cosmetics, mounts and pets appear inside the relevant game rather than in the launcher.

The browser equivalent lives in your Blizzard account settings: sign in, open your account overview, and use the “Redeem a Code” box there. Blizzard codes are usually region-locked, which matters more here than on most platforms — see the region section below.

GOG

1. Open GOG GALAXY
   Or skip straight to gog.com/redeem in a browser — GOG supports both equally, and the browser route is the better first choice if GALAXY is not already installed.
2. Click the cogwheel in the top-left, then “Add games & friends”
   This is the only launcher here where the redeem option is not under your profile.
3. Choose “Redeem GOG code”
   Enter the code, tick the “I’m not a robot” checkbox, and click continue.
4. Confirm the game shown
   GOG displays what the code contains before finalising. Click continue again to add it to your account.

Rockstar Games Launcher

1. Install and open the Rockstar Games Launcher
   Sign in with your Rockstar Games Social Club account. An internet connection is required — Rockstar codes cannot be redeemed offline.
2. Click your avatar, top-right, then “Redeem Code”
   The dropdown also holds your account settings, so make sure you pick the redemption entry.
3. Paste the code and click “Check”
   Rockstar rejects codes with leading or trailing spaces, which is the classic copy-paste failure. Select the code precisely, or type it out.
4. Verify the account details shown, then “Redeem”
   Rockstar deliberately shows which account the code is about to be applied to, and asks you to tick an agreement checkbox. Read that screen rather than clicking through it.

Microsoft Store & Xbox on PC

PC games bought through Microsoft — including Game Pass for PC codes and Play Anywhere titles — use a 25-character code, normally printed as five groups of five. You do not need to type the hyphens. There are three routes, all landing on the same Microsoft account:

• Browser: go to microsoft.com/redeem, sign in with the account that should receive the content, enter the 25-character code, select Next, then Confirm.
• Microsoft Store app: select your account picture in the top-right, choose “Redeem code or gift cards”, enter the code and select Next.
• Xbox app on PC: select your gamerpic in the top-left, open Settings, then enter the code and follow the prompts.

The four rules that apply everywhere

• Check which account is signed in before you redeem. Every platform here binds the game permanently to the account active at that moment, and none of them will move it afterwards.
• Paste rather than type where possible, but strip stray spaces. A trailing space copied out of an email is the single most common cause of a “code not recognised” error.
• Redeem once, then verify. If a code appears to fail, check your library before retrying — a code that actually succeeded but displayed an error will report as already used on the second attempt.
• Match the region of the key to the region of the account, not to where you are sitting. This is the rule that invalidates otherwise perfectly genuine keys.

When a key will not activate

Region locks on PC keys

Region locking behaves differently from store to store. Blizzard is the strictest of the group — Battle.net codes are usually tied to a specific region and will not apply to an account registered elsewhere. GOG sits at the other end, being DRM-free and generally the most permissive. Epic, EA, Ubisoft and Rockstar fall in between, applying region restrictions per title rather than universally, which is why the same store can sell you one key that works anywhere and another that does not.

“Nine out of ten “broken” PC keys we are asked about are not broken. They are being typed into the wrong launcher, or onto the wrong account. Confirm both before you assume the code is at fault.”
