Do Ethereum Addresses Start With a Zero or an O?

When it comes to cryptocurrency addresses, there is a lot of confusion surrounding the topic. One of the most common questions is whether Ethereum addresses start with a zero or an O. The answer to this question is actually quite simple. Ethereum addresses always start with a zero.

NOTE: WARNING: Do not confuse the letters ‘O’ and ‘0’ (zero) when looking at Ethereum addresses. Ethereum addresses always begin with a number ‘0’. Any address that begins with an ‘O’ is not an Ethereum address and should be treated with caution.

However, there are some exceptions to this rule. For instance, if you are using an ERC20 token, then the address will start with an O. Other than that, all Ethereum addresses will start with a zero.
