To register the product code for an Origin game, log into your Origin account, locate the Redeem Product Code link, enter the product code, and confirm the product. Electronic Arts offers two different platforms for customers to register product codes: a Web portal at EA.com and the Origin client for PC or Mac.
To use the Web-based platform, log in to an Origin account by clicking Log In at the top of the right corner of the page. After entering an email address and password, click on your user name at the top right of the page and click My Account from the drop-down menu. Select Redeem Product Code from the sidebar, enter the 16-digit product code in the text box at the center of the page, and click Next. After reviewing the product confirmation, click Next to enter the code.
To redeem a code using the Origin client, open it and enter the login credentials for the desired account. Click on Origin for the PC client or Games for the Mac client, then click on Redeem Product Code from the drop-down menu. From this point, enter the product code in the same way as for the Web-based client.
If you do not have an Origin account, register for one using either the Web portal or the Origin client.
