I didn't login from Iran, this is bullshit by Coinbase, a lot of people are complaining about it, coinbase is blocking their accounts without any reason. I have almost $1000+ in account and worried about it.
Maybe someone tried to hack into your account from Iran, or from a VPN server based there. Unfortunately, it sounds like you are going to need to fork over your ID and let them verify you before they will proceed. It sucks, but Coinbase is super worried about legal compliance, and this involves a sanctioned country. It sounds like if you verify your ID, they will unlock your account.
Since you're not a US resident and the amount of money is fairly small by money transmitter standards, I wouldn't worry too much at this point. I do hate giving my documents to exchanges, but Coinbase is one of the few that I've been willing to. Given their emphasis on compliance, they
should be putting a lot of resources into storing your documents and personal information securely.
But how can I send them documents? There's no link in support neither their email is working, it looks like they are thieves working underground without any proper support, no email, no support team, no contact information.
You can't send your documents via email. It's a real hassle: they make you upload your ID/passport via webcam while logged into the website, or with your smartphone's camera. My webcam wasn't good enough, so I had to use the mobile app. Find the official app, download it, and look for the ID section under "Settings." It was an automatic process. After taking a picture of my driver's license and a picture of myself holding it, my account was instantly verified.
Per their site:
Most ID verifications must be completed either through the Coinbase website or the mobile app. We are not able to accept emailed copies of ID for verification purposes.
Try using your mobile device. In some instances you can use the mobile app to complete the ID verification step using your phone's camera. The 'Identity Verification' section can be found under 'Settings' in the app.
For customers outside of the US, we are unable to accept scanned or otherwise saved image files. If you do not have a webcam on your computer, in most instances the mobile app or Mobile Camera option can be used to complete this step.
