ccTLDs in one minute
Two letters, one place
Each ccTLD matches a country or territory, mostly following the ISO 3166 code list: .jp for Japan, .br for Brazil, .nz for New Zealand.
Local rules
Every registry writes its own rules. Some extensions are open to anyone; others need a local address or business.
Some became words
.io, .ai, .tv and .me are country codes that found global second lives because of what their letters spell.
Not a ranking shortcut
Most ccTLDs tell search engines which country you're targeting. Rankings still come from content and reputation.
