When you send Monero to someone you only need one piece of information, and that is their Monero address. A *raw* Monero address is a set of 95 characters starting with a '4'. The Monero donation address, for instance, is <spanclass="long-term">44AFFq5kSiGBoZ4NMDwYtN18obc8AemS33DBLWs3H7otXft3XjrpDtQGv7SqSsaBYBb98uNbr2VBBEt7f2wfn3RVGQBEP3A</span>.
Because those addresses are long and complex you will often encounter an @OpenAlias address instead. For example, Monero donations can be sent to <spanclass="long-term">donate@getmonero.org</span> or <spanclass="long-term">donate.getmonero.org</span>.
An integrated address is an address combined with an encrypted 64-bit @payment-ID. A raw integrated address is 106 characters long.
### In-depth Information
The address is actually the concatenation, in Base58 format, of the *public*@spend-key and the *public*@view-key, prefixed with the network byte (the number 18 for Monero) and suffixed with the first four bytes of the Keccac-256 hash of the whole string (used as a checksum).
