🇮🇹 .it — Italy

The .it is a country-code top-level domain (ccTLD) operated by Istituto di Informatica e Telematica (IIT-CNR). This article documents the technical, operational, and contractual requirements for the TLD, along with special considerations for registry, registrar, and domain management.

Contact Attributes

.it carries two registry-specific attributes on the registrant contact, beyond the standard EPP fields. Both are required on registrations and inbound transfers:

Attribute	Type	Required	Applies to	Allowed values
`NIC_IT_ENTITY_TYPE`	Enum	✅ Required	Registrant	See the entity-type table below
`NIC_IT_REG_CODE`	String	✅ Required	Registrant	Tax or registration code, 1-36 chars (format depends on the entity type)

Entity types (`NIC_IT_ENTITY_TYPE`)

The registrant declares its legal nature through NIC_IT_ENTITY_TYPE. That value drives the nationality, organization, and registration-code rules below. The registry code is the number NIC.it echoes back in policy errors (e.g. "entity type = 1").

Value	Legal nature	Registry code	Natural person
`natural_person`	Natural person	1	✅
`company`	Company / one-person company	2	❌
`individual_firm`	Freelancer / sole proprietor	3	❌
`non_profit`	Non-profit organization	4	❌
`public_org`	Public organization	5	❌
`other`	Other entity	6	❌
`foreign_legal_entity`	Foreign (non-Italian) legal entity	7	❌

Registration code (`NIC_IT_REG_CODE`)

The expected format depends on the entity type and nationality:

Entity type	Expected code
`natural_person` (Italian)	16-character Codice Fiscale
`natural_person` (non-Italian)	Home-country identifier (no format check)
`company`, `public_org`, `other`	11-digit Partita IVA
`individual_firm`	Codice Fiscale or Partita IVA
`non_profit`	Partita IVA, or the literal `N.A.` when none exists
`foreign_legal_entity`	Home-country identifier (no format check)

Nationality, province, and organization

The registrant's standard fields are constrained by the entity type:

Country (contact.country):
- Italian legal types (company, individual_firm, non_profit, public_org, other) must be IT
- foreign_legal_entity must be a non-IT country in the EEA plus Vatican, San Marino, Switzerland, and the UK
- natural_person may be any country in that same EEA-plus set, including IT
Province (contact.state): required and must be a valid 2-letter Italian province code (e.g. RM, MI, NA) whenever the country is IT
Organization (contact.org):
- required for every legal-entity type
- for natural_person it must be omitted or equal the contact's full name

Per-role rules

.it is a thick registry with a registrant, admin, and tech contact. A few cross-role rules are enforced before the request reaches the registry:

the tech contact is required, on both create and update
for a natural_person registrant, the admin contact must reference the same contact as the registrant
the registrant is immutable through a normal update: omit it and the existing registrant is kept; it cannot be replaced via update

⚠️ Reusing one contact for every role? For a natural_person registrant the admin has to be that same contact, and any contacts update must still carry a tech. The two failures integrators hit most:

{
  "type": "policy-validation-error",
  "title": "Policy Validation Error",
  "status": 422,
  "code": "ERROR_POLICY_VALIDATION",
  "errors": [
    {
      "detail": "For 'natural_person' registrant, the admin contact must reference the same contact as the registrant",
      "pointer": "contacts.admin[0].contact_id"
    }
  ],
  "detail": "Policy validation failed"
}

{
  "type": "policy-validation-error",
  "title": "Policy Validation Error",
  "status": 422,
  "code": "ERROR_POLICY_VALIDATION",
  "errors": [
    {
      "detail": "Tech contact is required",
      "pointer": "contacts.tech"
    }
  ],
  "detail": "Policy validation failed"
}

The attribute constraints are machine-readable: each possible_attributes entry returned by GET /v1/tlds/it carries its own values, required, and contact_roles fields.

Registrant Policy Acknowledgement

.it registrations and inbound transfers require the registrar to confirm — on the registrant's behalf — compliance with the Registro .it (IIT-CNR) policies, and to pass those policies on to the domain owner. Surface the acknowledgement below to the end user before submitting a .it create or transfer; the confirmation is mandatory for both operations.

Privacy Policy	nic.it — Privacy Policy

Confirmation text

Present a single required checkbox. The registrant must accept it for the create or transfer to proceed. Suggested copy in English and German:

English

Please confirm that you comply with the following policies and that you will pass them on to the domain owner accordingly.

ℹ️ The acknowledgement is required for both .it registrations and inbound transfers. Capture the confirmation at the point of sale for each operation — a prior registration does not carry the acknowledgement over to a later transfer.
