A Bitcoin address is an identifier representing a possible destination — or origin — for a bitcoin transaction. Like an email address, each Bitcoin address is unique. Creating new or additional bitcoin addresses can be done free of charge through the installed bitcoin software, or you can obtain a bitcoin wallet address from an exchange or online wallet provider. There are three different Bitcoin address formats currently in use: P2PKH, PS2H, and Bech32. Each look different, but are always operable between each other to send and receive Bitcoin.
