Client wants .amazon. Not tld. Brand battle one. Checked icann. Complicated. Need help.
Client wants .amazon. Not the TLD, the brand battle one.
As far as I know, the .amazon TLD is under contract with Amazon since 2019 after a lengthy dispute with the Amazon Cooperation Treaty Organization. The governments of Brazil and Peru objected for years. The brand battle you mention was resolved in ICANN's favor of the corporation. The geographic region lost. There is no public registration possible for .amazon domains. Your client could consider .aws as pragmatic alternative. Or register a standard domain and use "amazon" as subdomain. To be precise, this is not legal advice.
Neuland. Aber schnell.
