## .co at a glance

- **Type**: Country-code TLD (ccTLD) of Colombia
- **Best for**: Startups, companies
- **How we check**: Registry RDAP where the registry publishes it, DNS otherwise. Each result says which one answered.

## Worth knowing

- People often type .com by habit. If you pick .co, consider owning the .com too, or at least check who has it.
- Email sent to the .com version of your address goes to whoever owns that domain, so be careful when the .com belongs to someone else.
- Two-letter and short dictionary .co names are largely gone, but compound names are often still available.
