Berechtigung & Einschränkungen

Open to anyone worldwide — individuals, foreign entities, legal persons. No residency requirement. No maximum on number of domains.

Registrierung

1 year minimum. Transfer includes 1-year renewal.

Transferverfahren

Auth code from registrar or directly from nic.cz/whois/send-password/ (sent to registrant and admin contacts). Auth code valid 14 days. Transfer completes within 24 hours. To generate auth code at registry: remove transfer lock — registry automatically emails registrant with new code.

📘 ICANN Transfer Policy (IRTP) — See ICANN Transfer Policy for the full IRTP framework, auth code rules, 60-day lock periods, and TEAC.

Inhaberwechsel

Owner change (trade) free of charge via ModifyDomain command. Registrant change done in real-time.

📘 ICANN OwnerChange (COR) — See ICANN OwnerChange for COR triggers, FOA/DA modes, 60-day lock, and opt-out.

Verlängerung & Löschung

Standard renewal. 60-day post-expiry protection: first 30 days domain still resolves; day 31-60 excluded from DNS zone but not yet available for registration.

📘 ICANN ERRP — See ICANN ERRP for the standard gTLD expiry lifecycle (Auto-Renew Grace → RGP → Pending Delete → Released).

Wiederherstellung / RGP

NO redemption period. Deleted domains available for re-registration immediately. No restore possible.

No redemption period. Once deleted, the domain is immediately available for re-registration by anyone. This is a critical difference from most TLDs. The 60-day protection only applies to expiry, not explicit deletion.

📘 ICANN ERRP — See ICANN ERRP for RGP details and standard restore fees.

WHOIS / Datenschutz

For organisations: name and address shown. For individuals: address can be hidden on request. Standard WHOIS service.

📘 ICANN Registration Data Policy — See Registration Data Policy for RDP 2025, RDAP, redaction defaults, and privacy/proxy rules.

NIS2-Konformität

No .CZ-specific NIS2 implementation documented beyond standard EU obligations.

📘 NIS2 Compliance — See NIS2 Compliance for Article 28 requirements, registry implementation status, and operational impact.
