Generating batches of addresses is useful in several scenarios, such as e-commerce websites where a unique pre-generated address is dispensed to each customer who chooses a "pay with Bitcoin" option.

Newer "HD wallets" can generate a "seed" token which can be used to allow untrusted systems such as webservers to generate an unlimited number of addresses without the ability to spend the bitcoins received. Old-style Bitcoin addresses are case-sensitive. Bitcoin addresses should be copied and pasted using the computer's clipboard wherever possible.

If you hand-key a Bitcoin address, and each character is not transcribed exactly - including capitalization - the incorrect 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 address 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 address 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 address for authentication only, in which case the 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 address. It is important to note that these signatures only prove one receives with an address.

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 addresses that begin with the number 1. If you would like to validate a Bitcoin 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 address 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. Addresses can be created that require a combination of multiple private keys.

Since these take advantage of newer features, they begin with the newer prefix of 3 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 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 addresses can be shorter than 34 characters as few as 26 and still be valid.

A significant percentage of Bitcoin addresses are only 33 characters, and some addresses may be even shorter. Every Bitcoin address stands for a number. These shorter addresses are valid simply because they stand for numbers that happen to start with zeroes, and when the zeroes are omitted, the encoded address gets shorter. Several of the characters inside a Bitcoin address 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 address is in fact valid and isn't simply an address with a missing character.

Addresses on the Bitcoin Testnet are generated with a different address version, which results in a different prefix. See List of address prefixes and Testnet for more details.
