Is 1800 ok to use in a domain name or is it a trademark?

[LaunchUp.com]

I saw alot of websites using 1800 in their domain name. But when i attempted to register a 1800 domain name, Godaddy said there is a possible trademark on 1800. Can someone expound on this for me please?

Like what if i wanted 1800.org or 1800cars.com o 1800.cab?

1800 itself cannot be trademarked if you try to register 1800gfdgfgdsdjh.com im sure its fine

Yes you can trademark 1800. Most people will think that 1800 means a 1-800 phone number but not in this case. The trademark is for the Tequila brand "1800"

The vast majority of 1800 domains that you see are based on the phone number. You will have no issues registering a 1800 name unless it has something to do with the Tequila. Godaddy's software picks out anything that has a trademark and tells you. Just because it has a trademark doesn't mean you can't use it for something in a totally different category.
