ccTLD

Country-Code Top-Level Domain — a TLD assigned to a country or territory using ISO 3166-1 alpha-2 codes (.uk, .de, .in, .cn).

ccTLD (Country-Code TLD) is a TLD delegated to a country or territory. The label is always a 2-letter ISO 3166-1 alpha-2 code — .uk, .de, .in, .cn, .jp, .br, .au.

Governance

Each ccTLD is operated by a national registry chosen by the country’s government or an ICANN-recognised sponsoring organisation. Rules vary widely.

Registration Restrictions

Some ccTLDs are open to anyone (.co, .io, .me — often used as gTLD-alternatives). Others require:

  • Local presence (.au requires ABN or citizenship, .fr requires EU nexus, .ca requires CIRA presence test)
  • Trademark holder status (.gov.uk, .mil.it)
  • Local trustee if the registrant is foreign

SEO Impact

Google uses ccTLD as a strong geographic signal. .de sites rank in Germany by default; .in sites rank in India. If you’re targeting a specific country, using its ccTLD is often better than an international gTLD.

Exception: “open” ccTLDs like .co, .io, .me are treated by Google as gTLDs, not as geographic signals.

Watch List

Some ccTLDs sold as gTLD-alternatives have had renewal-cost spikes after the country renegotiated the ICANN contract (.io, .tv). Consider registration cost stability before basing a business on a ccTLD.
