Registration

Registry allows up to 5 years. We currently offer 1 year. Transfer does NOT renew domain.

Transfer Procedure

Auth code (transfer key) created by losing registrar at registry; valid 30 days. Transfer key ≠ trade key. Using wrong code causes 'invalid code' error.

Trade key ≠ transfer key. Requesting the wrong type causes 'invalid code' failure. Auth code only available from losing registrar (who generates it at registry).

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

Registrant Change

Trade requires separate trade key (different from transfer auth code). Trade key sent to registrant by registry. Registry does NOT send confirmation email to domain contacts after trade. Tech handle for trade must be a company with registration number.

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

Renewal & Deletion

Standard renewal. Grace period exists after expiry.

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

Restore / Redemption Grace Period

Grace period after expiry. Restore process via registrar.

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

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