I know Bitcoin addresses start with 1, and it seems that testnet addresses start with m or n, and Namecoin addresses start with N, but is there a more complete list that would allow me to identify the coin type from an address? I hope this isn't offtopic, asking about other block chains.

I specifically want to know what these addresses are for (they're embedded in the executable linked to in this question):


but a complete list associating address prefixes with coin types would be more useful.


There is a list here, and a more detailed one here. 3 is indeed for a Bitcoin script hash.

  • I looked at blockexplorer.com/testnet/block/… to see some example testnet addresses. They start with 'm' and 'n' there... I'm guessing the wiki page is wrong. – Chris Moore Feb 18 '12 at 22:21
  • I was hoping for a more complete list - there are all kinds of altchains (solidcoin, litecoin, tenebrix, ixcoin, geistgeld (?), etc.), none of which I care about, but it would be useful to have a definitive list that would let me know what kind of an address I was looking at. – Chris Moore Feb 18 '12 at 22:22
  • The wiki page was changed in this revision: en.bitcoin.it/w/… - the same change which makes the page say things like "Bitcoin addresses always start with the digit '3'". – Chris Moore Feb 19 '12 at 1:41

    Sounds like the kind of edit Luke would make. I created a more complete list at en.bitcoin.it/wiki/List_of_address_prefixes , but it still requires some work. – Meni Rosenfeld Feb 19 '12 at 6:36

    @ChrisMoore Great work. – Meni Rosenfeld Feb 20 '12 at 9:10
