I am wondering if there is any way to check that a bitcoin address was created on an exchange.
For example, if I want to only interact with (send BTC to) people that have verified their identity (like on Coinbase), is there any way to check that their address is connected to a Coinbase account?
Thanks.

No, it's not possible at all. read more How does Bitcoin work

"Verified" addresses are not something you are likely to see, although could be implemented by trusting a 3rd party (if users choose to opt in). This isn't really the allure of Bitcoin, so I wouldn't expect such an idea to gain much traction.
Determining if an address belongs to an exchange, however, may be possible using blockchain analysis. By correlating inputs and outputs of a transaction known to be from an exchange, you may be able to determine with a varying degree off certainty other addresses and transactions that belong to that entity.

Such a verification would require the providing of specific evidence (such as a screen shot, which could still be faked) or a verification by Coinbase themselves. I wouldn't hold my breath for either of those options, if I were you.
Thanks. So there are no APIs or libraries available or made public by exchanges with lists of wallets created by their site for users? – John Murphy – 2018-02-01T11:01:00.640
No, because it's not possible with Bitcoin since there's no particular sign about how that address created or where. Bitcoin built to be like that. Anonymous. – Adam – 2018-02-01T11:34:03.480
Thanks. I realised that about bitcoin but was curious if exchanges made it public somehow through some APIs when they create those wallets.
I appreciate your help. – John Murphy – 2018-02-01T12:05:37.887
