Home world
You must choose a "home world" the first time you log on to the game; this determines the server you represent during World versus World and your Power of the Mists bonuses. All of your characters are bound to the same world. You can only change the home world after paying a substantial fee in gems and must wait a week before being able to transfer again. You may play with players on another world in the same region by guesting.
If a zone is overpopulated with players from the same world, the game automatically creates an overflow so that you can continue playing. You are also placed in a queue to transfer to your home world's version of the zone. Overflows are shared between all worlds in the same region and this allows players from different worlds to play together.
To transfer to a different world, go to the character selection screen (usingor when you first logon) and select the desired world; you will be logged out while the game makes these changes, which might take 5-30 minutes. You can transfer once every seven days at a cost determined by the destination server population.

The transfer fee is waived for accounts without any active characters. This allows people just starting out to change worlds for free; you also can transfer without cost if you delete all your existing characters. The next time you log on without any characters, you will be prompted to choose a new home world.  Please be aware that if you decide to delete the characters on your account, Customer Support cannot restore them, in whole or in part.
 Access to guild improvements on the new world
When you move, you will lose access to all your guild improvements on your original world (unless you move back). This includes any guild vault and all of its contents. Accordingly, if you have any items stored in a group or personal guild vault, be sure to move them to one of your existing characters and/or your personal bank before transferring.
Guesting allows you to play with friends on other worlds in the same region without transferring. Guests retain guild bonuses from their home world and any influence earned will accrue to their home world's guild. Guests cannot participate in World versus World and do not receive any Power of the Mists bonuses. As might be expected, if you guest to a full world, you increase your chances of ending up in overflow.
Players on North American home worlds cannot guest on European worlds or vice versa.
 How to guest
From the character selection screen, choose World Selection. Choose the world to which you wish to guest and click on the Guest button (next to the Transfer button). After confirming your choice, the game will place a suitcase icon symbol next to the guest world. The next character you play will be guesting on that server and continue to do so until you logout, change characters, or restart the current character. To guest again (or with another character), repeat the same steps.
You are eligible to guest as many times as you like, but you may only choose up to two guest worlds every 24 hours.
Caution: double-check when guesting that you have not accidentally started the transfer process; the buttons are very close together and the prompts are similar.
 Guesting alternatives
There are three situations in which you can play with people in other worlds without guesting to their server. You must be in the same party and everyone must be from the same region (North America or EU).
- Any overflow — right-click on a character's name in the party menu and choose, join in [zone].
- Dungeons and Fractals of the Mists — to enter the same instance, all five party members must be in the zone that contains the dungeon before entering.
- Personal stories — with the same restriction as for dungeons.
Guilds are not tied to any specific world; all players can join any guild regardless of which world they play on. However, influence and guild upgrades are specific to each world: players in the same guild but on different worlds will contribute to separate influence pools and build through separate upgrade trees. Members that transfer will have to regenerate influence and build new upgrades on the new world.

 Origin of names
Each world is named after a location in the world of Tyria with a few exceptions, named after the following people:
- 1 Kevin Ehmry, an ArenaNet employee.
- 2 Mike Ferguson, an ArenaNet employee.
- 3 Roger "Oldroar" Rall, a fan who died before the game was released. 
- 4 Chris Whiteside, an ArenaNet employee.
- 5 Stefan Baruch, one of the henchmen from Guild Wars Prophecies.
- You cannot move to a world that is listed as Full. However, that status varies throughout the day and tends to drop during off-peak hours, i.e. if you are unable to transfer, try again when there are fewer people playing, e.g. early in the morning (server time) or during the work week.
- Players have designated certain worlds with tags that they feel will help others find a server whose players match their own interests, e.g. role playing or Polish speakers. However, the wiki does not list them for several reasons: they are unofficial, subject to change without warning, and unverifiable (e.g. no one can say that World A has more Esperanto-speakers than World B or whether World C has "a lot" of role players).
- Due to concerns about the effect of frequent transfers on World versus World, ArenaNet imposed a 24-hour waiting period on changing servers; this was later extended to 7-days for the same reason.
- Guesting was introduced on January 28, 2013; prior to that date, it was free to transfer servers within the relevant waiting period.
