MT Intelligence
a.co is owned and operated by Amazon.com, Inc., registered on 2010-04-26 with active status through 2027. Our antivirus network reports zero detections across 92 engines, and the hosting IP carries no abuse reports. The domain is locked with multiple WHOIS protections typical of high-value corporate assets. Web research confirms a.co is Amazon's branded shortener used alongside amzn.to for product links and mobile app shares. Scammers sometimes impersonate Amazon using lookalike domains or other shorteners like cutt.ly, but a.co itself is legitimate. The blank page appearance is expected for a redirect service — users don't visit a.co directly; they follow shortened links that redirect to Amazon product pages.

Still, stay alert
No major threat indicators — but a clean scan does not guarantee every page is safe, and phishing emails routinely spoof real domains.
- Double-check the exact URL in your address bar
Confirm you are actually on a.co and not a lookalike like a-.co.com or an IDN homoglyph.
- Use a password manager
Password managers only auto-fill on the exact domain they were saved for — they refuse to fill lookalike domains, which is the single best phishing defence.
- OpenDiscuss this site on the forum

Safety FAQ
Common questions about this site, answered directly from the scan data above — so the answers always reflect the latest verdict on this page.
- Our automated security review found no threat indicators on a.co. The site appears legitimate based on the signals we checked, but always stay alert for phishing emails that spoof real domains.
- a.co passed our automated security checks with a trust score of 96/100. No antivirus engines or major blacklists flagged the site at the time of the last scan.
- Yes. a.co presents a valid TLSv1.3 certificate issued by Amazon · Amazon RSA 2048 M01, expiring in 61 days. Note that SSL only encrypts the connection — it does not guarantee that the site itself is trustworthy.

- No. a.co is not currently listed on the major browser blocklist feeds that modern browsers use.
- a.co resolves to an IP operated by Amazon Data Services Northern Virginia in US (usage type: Data Center/Web Hosting/Transit). Hosting location alone doesn't make a site good or bad, but unusual geography for a brand's claimed country is one of many signals we weigh.
- Yes. a.co sits in the global top-100k on Cloudflare Radar, which means it has substantial real-world traffic. That does not automatically make it safe, but established brands almost always rank here and throwaway scam domains almost never do.
- This is a permanent record of the scan run on June 17, 2026. The verdict and evidence above reflect that scan and do not change on their own. If circumstances around a.co have changed, MalwareTips staff can run a fresh scan, which re-runs every check from scratch and publishes an updated report.
