Find Bitcoin wallet ID

You can find your wallet address in the Account Settings page under the the Bitcoin Addresses tab:

You'll see that you may have multiple addresses associated with your account - you can use any of these addresses for receiving bitcoin and it will fund your Coinbase account. Don't be alarmed if you see addresses that you don't remember creating - we automatically generate a new address for every transaction and whenever we move funds between your wallet and our cold storage system.

From this view, you can see a QR code which can be embedded in your website (for example). You can also set a label so you can keep track of which address you've used for what.

You can also specify a callback URL. This is an advanced feature used by developers to notify their apps when a bitcoin payment is received by an address. Normally, you don't have to worry about callbacks unless you're working with our API to develop your own application.
