<p>I realize this can be done at blockchain.info, but would like to find a way to do this with just the bitcoind client. if all I have is the receiving address and the transaction number, I can't figure out what command or set of commands to use. I can get and decode the raw transaction (<code>bitcoind decoderawtransaction $(bitcoind getrawtransaction 3dd264f603f75871c5a36b61db8e137d8cee6b019a8d5bdfdabd7383ccc47068) | less</code>), but that doesn't give me the block number. </p>

<p>note that I can't use <code>gettransaction</code> because my local box (netbook) isn't the origin nor the destination of the transaction; I get <code>error: {"code":-5,"message":"Invalid or non-wallet transaction id"}</code>. I also can't use <code>listreceivedbyaddress</code> for the same reason, although I don't get an error in this case because I did once send to the address in question from my netbook.</p>

note to people coming across this question: don't mark down Luca's answer, I hadn't made it clear at the beginning that I couldn't use  gettransaction. added that  in just now.

This may be impossible to do without looking up each block down until you get to one that contains it.

yeah, I'm beginning to think that's probably my only option. I guess that's what blockchain.info does too, just loads all the blocks into a database.

If you're good with Javascript this can be done easily with [Bitcore](http://bitcore.io/). It's really interesting and powerful.

how does one map a transaction number to a block with just the bitcoind client?

I realize this can be done at blockchain.info, but would like to find a way to do this with just the bitcoind client. if all I have is the receiving address and the transaction number, I can't figure out what command or set of commands to use. I can get and decode the raw transaction (`bitcoind decoderawtransaction $(bitcoind getrawtransaction 3dd264f603f75871c5a36b61db8e137d8cee6b019a8d5bdfdabd7383ccc47068) | less`), but that doesn't give me the block number.

note that I can't use `gettransaction` because my local box (netbook) isn't the origin nor the destination of the transaction; I get `error: {"code":-5,"message":"Invalid or non-wallet transaction id"}`. I also can't use `listreceivedbyaddress` for the same reason, although I don't get an error in this case because I did once send to the address in question from my netbook.

figured it out after finding my own previous post about how I found out this info with americancoind, [coin seems to have gone to a duplicate address](https://bitcoin.stackexchange.com/questions/19971/coin-seems-to-have-gone-to-a-duplicate-address), by its error message on attempting to resend the raw transaction. but bitcoind doesn't tell you what block it's in, merely stating `error: {"code":-5,"message":"transaction already in block chain"}`. however, on searching through the source (rpcrawtransaction.cpp) I noticed that getrawtransaction takes an extra arg, verbose, which if greater than 0 gives the blockhash:

```
jcomeau@aspire:~/rentacoder/jcomeau/bitcoin/src$ bitcoind getrawtransaction 3dd264f603f75871c5a36b61db8e137d8cee6b019a8d5bdfdabd7383ccc47068 1 | grep block
    "blockhash" : "000000000000000116f3abab7d0f620f620eae189de29ddb06fe8baae566467a",
    "blocktime" : 1393013064

```

and with the blockhash you can use getblock:

```
jcomeau@aspire:~/rentacoder/jcomeau/bitcoin/src$ bitcoind getblock 000000000000000116f3abab7d0f620f620eae189de29ddb06fe8baae566467a
{
    "hash" : "000000000000000116f3abab7d0f620f620eae189de29ddb06fe8baae566467a",
    "confirmations" : 255,
    "size" : 341358,
    "height" : 287092,
    "version" : 2,
    "merkleroot" : "d0fd6154ba64682b48c9c15600ee7c8594336cf4c0a2917b5cbcf1f5a74d2096",

```

so, 287092 is the block number that contains the transaction.
