Binds to Blizzard account (as of Patch 7.2; aka BtA; changes to Blizzard Account Bound after binding; previously "Bind to Account" or "Binds to account", "Binds to Battle.net account" as of Patch 4.1) is a new form of item binding that was introduced in Patch 3.0.2. Items that are BtA include heirlooms, Collector's Edition companions, the , and the .
Many players incorrectly use the term BoA instead of BtA to match BoP and BoE. Sometimes any Bind to Account items are referred to as "heirlooms" even though they are not technically the same (they usually don't scale, unlike true heirlooms).
"BoAs" as many people call them can be bought from many rep. vendors, including bought from points in Dalaran and Honor points in Wintergrasp
As of Patch 5.4.2, account-bound items can be mailed to characters on the same account, even on different realms and across factions. You simply type the character's name then a "-" followed by the realm the character is on. Some naming rules apply for realm names, since they can have spaces and apostrophes, unlike characters names.
As of Patch 4.1, account-bound items can be mailed from characters attached to different World of Warcraft accounts if they are under the same Battle.net account and on the same realm. Also, faction-specific items will be translated to the faction equivalent, if changing factions.
Starting with Wrath of the Lich King, account-bound items can be mailed to any character that shares the same account and server. Since Patch 3.3.0, account-bound items can be mailed to characters of opposing faction.
