 The Sui address is unique, similarly to the way a social security number or a personal identification number is unique to one person. However, in Sui you can create and own multiple addresses, all of which are unique. 
 
-In Sui, an address is 32 bytes and is often encoded in base58 with a `0x` prefix. For example, this is a valid Sui address: `0x02a212de6a9dfa3a69e22387acfbafbb1a9e591bd9d636e7895dcfc8de05f331`. You can use a Sui network explorer to find more information about this address and the objects it owns.

 If you'd like to understand how a Sui address is derived from private keys and other cryptography related topics, see the [Keys and Addresses](/concepts/cryptography/transaction-auth/keys-addresses.mdx) topic.
