  "title": "Spain Census Declaration for Natural Persons (Declaración Censal, Modelo 030)",
  "description": "The Agencia Estatal de Administración Tributaria's (AEAT, Spain's tax authority) Modelo 030, 'Declaración censal de alta en el Censo de obligados tributarios, cambio de domicilio y/o de variación de datos personales' — the simplified census declaration a natural person (persona física) not carrying out a business/professional activity uses to register in Spain's Censo de Obligados Tributarios for the first time, request a NIF when they hold no DNI/NIE, change their fiscal or notification domicile, update identifying data (name, nationality, birth data), report a change of civil status, or add/withdraw a phone number or email address AEAT may use for informational notices. A single Section 1 ('Causas de presentación') carries fifteen checkboxes — one pair (interesado/cónyuge) per cause, plus one interesado-only cause for phone/email notices — that determine which of the form's other conditional sections (2/3 identifying data, 5 fiscal domicile, 9 civil status) are completed; Sections 4 (phone/email), 6 (foreign domicile), 7 (notification domicile), and 8 (representative) are available regardless of which Section 1 cause is marked. The form is genuinely downloadable and fillable (a 4-page AcroForm PDF hosted directly on sede.agenciatributaria.gob.es, HTTP 200, no login/CAPTCHA/WAF gate; pages 3-4 are an identical duplicate 'Ejemplar para el interesado' copy of pages 1-2's 'Ejemplar para la Administración', not modeled separately). This document opens Spain as a new jurisdiction in this registry. Deliberately does not model: the electronic-filing channel (Modelo 030 can also be submitted through AEAT's authenticated Sede Electrónica, an entirely different, session-based flow this document does not attempt to describe); the external AEAT code tables the 'Clave' fields in Section 8 and the country-code field in Section 6 reference, none of which are reproduced inside this 2-page form; and the physical-signature line itself, which is not applicant-supplied data. GovSchema is independent and is not affiliated with, endorsed by, or operated by the Government of Spain or the Agencia Estatal de Administración Tributaria.",

Screened alongside Chile's remaining Passport/National ID/Visa gaps (all re-confirmed ClaveÚnica-gated or non-resolving, no fillable form found), Peru's Migraciones/RENIEC channels (a genuine Peru PDF exists — SOLICITUD-GENERAL.pdf — but carries no AcroForm layer at all; RENIEC's own DNI-renewal app is a reCAPTCHA-enterprise-gated Angular SPA), and Argentina's RENAPER (appointment/Mi Argentina-app gated, no downloadable form found) — see VERIFICATION.md for the full candidate comparison. The live PDF was independently fetched (HTTP 200, no login/CAPTCHA/WAF) and its AcroForm field structure extracted via pdfjs-dist (annotation/widget layer plus page text layer, cross-referenced by x/y-coordinate and corroborated with a rendered page-image visual check via pdfjs-dist+canvas at 3x zoom), since — like the sibling cl/sii/aviso-venta-vehiculo schema's F1816 — this form's AcroForm field names are generic (dato.1...dato.135) and carry no descriptive information of their own; each field's real printed label and reference-number box were attributed by matching widget rects against the nearest label text and confirmed visually against the rendered page image. See VERIFICATION.md for the full field inventory, sourcing, and every disclosed judgment call."
