Bank
A bank is a building with several teller NPCs that allow a character to access a private storage area that is accessible from any bank branch. Branches appear in major cities and some towns, and allow a character to store items not currently in use. However, the term "bank" is usually used to refer to the storage space itself, rather than the physical structure.
All of the banks share the same vault; the neutral banks are equivalent to the faction banks. If you place items in one bank, you will be able to access them in another. (Canonically, this is accomplished through the use of Automated Teleportation Modules; ATM's for short.) However, players are not able to use the banks of opposing factions, because they cannot talk to the tellers.
Bank space
Initially, a character's bank account (vault storage space) contains 28 item storage slots at no cost. An additional seven bag slots for more space are purchasable. These provide no additional item storage slots but allow placement of a bag that has item storage capacity. The bags can be changed out and it is common practice to progressively place larger bags. The cost of the bag slots increases with each extra slot purchased starting at 10
, then increasing to 1
, 10, 25, 25, 25, 25, for a total of 111 10 for all slots (not including the bags that go into them).
Players can craft using materials currently stored in the bank, from anywhere in the world, without needing to retrieve the items first.
Unlike a real bank, you cannot store currency within the bank, only items.

Bank alts

Where can I find bank branches?
- Main article: List of bank locations
Most bank branches can be found in Capital cities. Some banks are only available to a specific faction such as in Shattrath City the two available banks are separated by the factions Aldor and the Scryers.
Portable banks
Portable banks can be carried with players as items or abilities, giving access to the bank anywhere in the game. They reduce a player's need to travel to a bank, but, due to their long cooldowns (often an hour or more), they do not completely remove it.
Known portable banks:
[Jeeves] (bank only accessible by engineers)
[Argent Squire]/
[Argent Gruntling] (when upgraded with an 
[Argent Pony Bridle])
[Pack Hobgoblin] (goblin racial ability)
[Mobile Banking] (will access your guild bank)
[Sassy Imp] (one of his random service)
