“Guilds are a great way to connect to a community and make new friends. Each guild has it's  own chat channel and list of members to see who's available to play with. Members cooperate to purchase additional upgrades such as leveling bonuses, shared item vaults, and the ability to throw parties. You may join a guild or start your own!
— Guild interface
Guilds are formal groupings of players that enable them to play together more effectively and reward them for doing so.
To create a guild, open the guild panel ( ) and click on the "Create Guild" button. You will be asked to enter a guild name (up to 31 characters) and a tag of up to four characters. Alternatively, speak to a Guild Registrar in any of the major cities. It costs 1 to create a guild.
Guild membership is administered at the account level, and an account can hold membership in up to 5 guilds. Joining a guild requires an invitation sent from an existing member of the guild. Your open invitations can be found on the front tab of the guild panel, on the left, under "Invitations."
- To accept an invitation to join a guild, select the guild in the "Invitations" list, then click the "Join Guild" button at the bottom of the window.
- To leave a guild, select the guild from the "Account Guilds" list, then click the "Leave Guild" button at the bottom of the window.
- If you are currently representing the guild (see below), you will need to click "Stand Down" first.
Guild membership is not limited to a single world — a guild can have members from any server, whether in the US or EU. However, the guild's influence pool and upgrades (including the Guild Vault) are specific to each world, just like a social club would need to acquire separate furniture for each of its branch offices.
Initially, each guild is limited to 50 members. You can purchase the following capacity upgrades:
While guild membership is at the account level, guild representation is at the character level, providing access to guild chat, the guild bank, and any active guild upgrades. In addition, influence generated by activities accrues to the guild currently represented by the character.
To represent a guild, open the guild panel. On the left, under "Account Guilds," will be a list of all guilds your account is a member of; select one and then click the "Represent" button at the bottom of the window. You must do this individually for each character, since joining a guild does not automatically require you to represent it. Similarly, newly-created characters will not represent a guild until you select one for them.
To end a character's representation of a guild, choose Stand Down; the character will still belong to the guild, but not be able to use any of that guild's perks.
 Member ranks
Each guild can organize members into ranks; up to 10 ranks can be created, and the titles and the permissions of each rank can be customized. To change a member's rank, open the guild roster, and right-click their rank icon. Use caution when editing ranks or promoting people; it is possible to accidentally remove leadership privileges from your rank.
The default ranks and their permissions are given below.
- 1 Be careful administering your own rank, since you can accidentally remove privileges preventing you from further administration.
- 2 This setting is required to invite new members. Leaders are able to demote others with the same rank.
- 3 Specifies the rank that new members are assigned when they join.
- Primary article: Influence
Members earn influence for the guild that their character represents by being present and participating in activities. The more members that participate together, the faster the guild gains influence, which can be used to purchase upgrades for the guild in four categories:
- Architecture — Purchase shared storage and increase the number of upgrades the guild can work on at once.
- Art of War — Buffs used in WvW
- Economy — Buffs to increase members ability to earn karma, find magic items, or gather materials.
- Politics — Emblems, influence buffs, guild armor, and party items.
 Guild Vault
- Primary article: Guild Vault
Guilds can create a Guild Vault using Influence, providing 50 storage slots shared by all members of the guild with sufficient privileges. Additional upgrades can be built that increase this space to 250 slots. The Guild Vault is accessed by speaking to a Guild Banker, located near Banks in major cities.
 World versus World
- Primary article: World versus World#Guilds
Under the Art of War category, guilds can build upgrades that provide bonuses in World versus World. These bonuses become active when the guild claims an objective (supply camp, tower, or keep) and are granted to all allied players defending that objective.
 Guild emblem
Under the Politics category, guilds can build a "Guild Emblem Template" upgrade that allows members with the appropriate permission to create or modify an emblem for the guild by speaking to a Guild Registrar. Emblems consist of a two-color symbol overlaid on a single-color background pattern.
After an emblem is created, it will display in the guild panel and on any objective claimed by the guild in WvW. After building the Guild Armorer Contract or Guild Weaponsmith Contract upgrades, members can purchase armor or weapons, respectively, that will also display the guild emblem.
- The gallery of guild emblems shows all available symbols and backgrounds.
- The emblem shown on guild armor or weapons is determined by the guild the character is representing. If you are not representing a guild, then no emblem will be shown.
 Guild Missions
- Primary article: Guild mission
Added in the Flame and Frost: The Gathering Storm update, these missions are unlocked with Influence and require co-operation of all guild members to complete. They allow members to earn Guild Commendations and the guild itself to earn Guild Merits.
- There is no limit to the number of people assigned to each rank; you can have several people with all the privileges of leadership. Any of these players can demote any other.
- During the first and second beta weekend events, guild creation was free.
- There are no Guild Halls and the company is no longer actively working on them, but they do plan to have them some day.
