Is .co a good alternative to .com?

It is the closest widely-accepted alternative, and short meaningful names are far more available. The trade-off is real though: some visitors will type the .com out of habit, so if that .com is held by someone else you may lose traffic and misdirected email to them.

Do I need a Colombian address for a .co domain?

No. .co is operated as an open extension available worldwide with no local presence requirement.

.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.

What .co actually signals

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.
