.co domain names
One letter from .com, with far more still available.
Quick answer
.co is the country-code extension for Colombia, marketed globally as a short alternative to .com and commonly read as "company". Its strength is availability of short, meaningful names; its weakness is that traffic and email can leak to the matching .com when people mistype.

- Operated as an open global extension despite being a ccTLD, with no local presence requirement.
- One character shorter than .com and visually close to it, which is both the appeal and the risk.
- Widely used by startups that wanted a specific word and found the .com unavailable or unaffordable.
