If you hand-key a Bitcoin invoice address, and each character is not transcribed exactly - including capitalization - the incorrect invoice address will most likely be rejected by the Bitcoin software. You will have to check your entry and try again. The probability that a mistyped invoice is accepted as being valid is 1 in 2 32 , that is, approximately 1 in 4. Most Bitcoin wallets have a function to "sign" a message, proving the entity receiving funds with an invoice has agreed to the message.
This can be used to, for example, finalise a contract in a cryptographically provable way prior to making payment for it. Some services will also piggy-back on this capability by dedicating a specific invoice address for authentication only, in which case the invoice address should never be used for actual Bitcoin transactions.
When you login to or use their service, you will provide a signature proving you are the same person with the pre-negotiated invoice address. It is important to note that these signatures only prove one receives with an invoice. Since Bitcoin transactions do not have a "from" address, you cannot prove you are the sender of funds. Current standards for message signatures are only compatible with "version zero" bitcoin invoice addresses that begin with the number 1.
If you would like to validate a Bitcoin invoice address in an application, it is advisable to use a method from this thread rather than to just check for string length, allowed characters, or that the invoice starts with a 1 or 3. Validation may also be done using open source code available in various languages or with an online validating tool.
Invoices can be created for keys that require a combination of multiple private keys. Since these take advantage of newer features, they begin with the newer prefix of 3 or bc1 instead of the older 1.
These can be thought of as the equivalent of writing a check to two parties - "pay to the order of somebody AND somebody else" - where both parties must endorse the check in order to receive the funds. The actual requirement number of private keys needed, their corresponding public keys, etc. Most Bitcoin invoice addresses are 34 characters. They consist of random digits and uppercase and lowercase letters, with the exception that the uppercase letter "O", uppercase letter "I", lowercase letter "l", and the number "0" are never used to prevent visual ambiguity.
Some Bitcoin invoice addresses can be shorter than 34 characters as few as 26 and still be valid. A significant percentage of Bitcoin invoice addresses are only 33 characters, and some invoices may be even shorter.
Technically, every Bitcoin invoice stands for a number. These shorter invoices are valid simply because they stand for numbers that happen to start with zeroes, and when the zeroes are omitted, the encoded invoice address gets shorter.
Several of the characters inside a Bitcoin invoice are used as a checksum so that typographical errors can be automatically found and rejected. The checksum also allows Bitcoin software to confirm that a character or shorter invoice is in fact valid and isn't simply an invoice with a missing character.
Invoice addresses on the Bitcoin Testnet are generated with a different prefix. See List of address prefixes and Testnet for more details. Invoice addresses are not intended to be used more than once, and doing so has numerous problems associated. See the dedicated article on address reuse for more details. Invoice addresses are not wallets nor accounts, and do not carry balances.
They only receive funds, and you do not send "from" an address at any time. Various confusing services and software display bitcoins received with an invoice address, minus bitcoins sent in random unrelated transactions as an "address balance", but this number is not meaningful: it does not imply the recipient of the bitcoins sent to the address has spent them, nor that they still have or don't have the bitcoins received.
An example of bitcoin loss resulting from this misunderstanding is when people believed their invoice address contained 3 BTC. You can sum up all your worth in bitcoins and get settled in another country altogether with the help of a Bitcoin address.
