Finding Your Serial Code

Your Guild Wars 2 serial code is a 25-digit alphanumeric string formatted like the following code:


Your serial code is a unique key that will let you unlock the game, add an expansion pack, or unlock other new features on your ArenaNet account. A game or expansion serial code can also be applied to a free account to not only unlock the content provided by the key, but upgrade your account and remove the free account restrictions.

Where do I find my serial code?

If you purchased a physical copy of the game, your serial code is located inside the box. You should find it printed on a paper insert inside the disc case.

If you purchased the game directly from, your serial code was sent to the email address provided during the checkout process. Note that this can be a different address than the one used to activate the key and log in to the game.

What should I do if I lost my serial code?

In most cases, you won’t need your serial code once it's been used to unlock the game. That said, we highly recommend storing or saving your serial code in a safe place, since it can be used as a unique identifier that will help you verify ownership of your account if something ever happens to it. Please note that support will not be able to provide this information if you misplace your code.

If you can't find your serial code, you can also include other identifying details to help the team verify ownership of your account. This includes:

  • The full name on the account
  • Your date of birth
  • The phone number used on the account
  • The last four digits of the credit card on the account
  • etc.

Include this information in a support ticket and we’ll do our best to help you!
