Hi,

If i send bitcoins from my blockchain wallet to my coinbase wallet, is it possible to know that the coins came from a coinbase wallet by the bitcoin address?

No, not unless the service who owns and controls the address places their unique 'tag' on the transaction, otherwise it's basically just like any other address. Usually, services like blockchain.info and Coinbase don't really place their unique 'tags' or markings on any of the address they control. Gambling sites, however, do place their tags on addresses and on every transaction they create. Take a look at this example from Luckybit ^{(not a promotion, anyway)}

DEFINITELY, we are on blockchain technology! they will not know who you are but your address will remain!
There will be safe on your side as long as you are not doing any KYC. though the address will be kept on track!

certainly it cannot be detected from where the shipment came from, because this block system is a bitcoin chain called Peer-to-peer

You are missing something unless there's some conditions just like what was mentioned above.

I wish it could happen, this would also have helped in recognizing scammers and bust them more quick.
There is a service called https://walletexplorer.com where you can try your luck and maybe know as well which address belongs to which wallet (it may not show you names probably but it can definitely show you connections). They try their best to label addresses and wallets to their specific Services.

If your address is not known by someone, no. When we say that Blockchain is decentralized, that is exactly what we are talking about. The centralized exchange here is also involved, but it does not matter because in most exchanges everyone has own BTC address.

The answer to your question is complicated. There is no way to associate an address with a service just by the address itself. Addresses are effectively random.

However, addresses can sometimes be associated with services by analyzing the transactions that use them and analyzing how they are used in those transactions. Here is an example regarding blockchain.info:

When blockchain.info started out, each account was given a single address and that address was reused. In general, no other wallets did that. So, you could look at a transaction and deduce that it was a blockchain.info wallet if the change was sent back to the input address. Thankfully, that behavior is gone now that blockchain.info has moved to HD wallets.

Out of curiosity, are you trying to trying to look for an anonymous solution to send/receive Bitcoin? If yes, then whatever the answer to this question is, you need another technique to increase your anonymity. You can try CoinJoin or a mixer in order to make your transactions more anonymous, therefore blockchain analysis will at least require some time to find out which address is yours.

Yes of course, I'm sure you've heard this before: "Bitcoin's transaction aren't anonymous but rather pseudo-anonymous[/i]."

Coinbase is a centralized wallet and exchange and can be easily analyzed using any blockchain analysis tool (https://www.walletexplorer.com/) since they "consolidate" most of the inputs using multiple and different (deposit) addresses, using addresses' inputs together will link them to the same wallet used by any one of those addresses.
Although using that tool (link above) is as easy as checking a transaction/address in a blockexplorer, a normal internet guy might find it hard but not the authorities with sophisticated tools and agents, they can always find a way.

And in addition, your KYC data is always available for the Gov't and Coinbase to see and every deposit address you've generated will be marked as "yours".

Next time, post questions like this in the Bitcoin Technical Support board in order to get more accurate answers.

It is a rather complicated to answer the question. You can just base the answer from feedbacks here. First, No you can't see or check where the coins yoy get came from. Second is you know who send you the coins or refer to dothebeats reply which is true when it is gambling sites.
