This domain borrows the Coinbase name, which should immediately raise alarm for anyone in the crypto space. Legitimate exchanges use their own branded domains, not numeric prefixes or odd subdomains. The SSL certificate doesn't match the site, a classic sign of either misconfiguration or impersonation. Google Safe Browsing has flagged it for social engineering, meaning real users have reported it for deceptive behavior. The site is also unreachable. On paper there are privacy and terms pages, but these are easy to copy and don't outweigh the core security failures. If you're wondering whether 1789503-coinbase.com is a scam, the evidence says yes. Stick to the official Coinbase website and avoid any variations with numbers or unusual subdomains — that's the safest move for your crypto and personal data.
No — 1789503-coinbase.com doesn't look safe
In plain English
This site is dangerous. It uses a fake SSL certificate and is flagged by Google for social engineering — both clear signs of a phishing operation. The domain name mimics Coinbase, so you should stay far away.

Where the score comes from
This site has a catastrophic security failure. The SSL certificate belongs to a different domain entirely, and Google Safe Browsing has flagged it for social engineering, meaning it's actively used in phishing or deception attacks.
The domain name copies Coinbase, a well-known crypto exchange, which is a clear impersonation tactic. While a business disclosure page exists, the registrant hides behind a budget registrar and no direct ownership details are publicly available.
Google's warning for social engineering is a decisive red flag — this site is known to trick visitors. It has no history in the Wayback Machine and zero independent trust signals, making its reputation critically poor.
An About page and business disclosure are present, which is better than nothing. But the absence of any contact information or social media, combined with the site being unreachable, leaves its operators effectively anonymous.
Privacy policy and terms of service exist, meeting basic legal boxes. For a site trading on the Coinbase name, however, missing clear contact details and financial-compliance disclosures is a meaningful gap.
Hosting on Amazon Web Services is solid, but the SSL certificate mismatch is a severe technical failure that makes the site inaccessible and untrustworthy. Email and DNS setup are otherwise passable.
