This is a GovSchema Standard Research cycle (GOV-3328), a general research-analyst brief covering DMV, Business Formation, Visa, Passport, Taxes, and National ID & Civic Documents across all jurisdictions.

Why this candidate

Ecuador opened as this registry's 65th jurisdiction only three cycles ago (GOV-3305), with a single vertical modelled — Visa, via ec/cancilleria/formulario-solicitud-visa. That schema's own VERIFICATION.md recorded SRI's web server (www.sri.gob.ec) as unreachable at the time ("connection timeout, curl exit 28"), leaving it un-pursued as a candidate for Ecuador's Business Formation vertical. This cycle re-checked SRI first rather than opening a 66th brand-new jurisdiction, since Ecuador, Ethiopia, and Georgia (the registry's three newest jurisdictions, each opened in the immediately preceding cycles) each still have 5 of their 6 verticals open — building out an already-open jurisdiction's next vertical is preferred over adding jurisdiction #66 when a live, well-sourced candidate is available.

SRI's server responded normally this cycle (HTTP 200 on every fetch, with a realistic desktop User-Agent header set) to both of the documents this schema is built from. Other Ecuadorian candidates screened this cycle and found weaker:

• Registro Civil passport renewal/first-issue: requires an already-created Agencia Virtual account (login-gated), with no downloadable field-by-field form found describing the online wizard's own structure.
• Registro Civil "Duplicado de cédula Express" (apps.registrocivil.gob.ec/portalCiudadano/cedulaexpress/): a genuine live, unauthenticated JSF/PrimeFaces application — confirmed live via direct curl and a real Playwright/Chromium session (screenshot captured) — but its entire visible field surface is a 3-field search step (10-digit cédula/NUI number, date of birth, and an image CAPTCHA); the actual duplicate-request/payment step that would follow a successful search is rendered server-side only after that CAPTCHA is solved against a real citizen's own registered data, which this cycle could not do without impersonating a real person. Left as a disclosed, thin, gated candidate — see "Known gaps" below — rather than authored as a 3-field schema.
• ANT (Agencia Nacional de Tránsito) vehicle-registration forms: the live ant.gob.ec/index.php/formularios page itself did not respond to a direct connection attempt this cycle; a Wayback Machine snapshot (dated 2020-09-20, the most recent full crawl found) resolves instead, but its form inventory is almost entirely heavy-transport/commercial-fleet paperwork (refund requests, transport-permit renewals, web-service access forms for professional transport operators) with no core "vehicle registration/matriculación" application form among the indexed links — weaker than the RUC candidate below.

SRI's RUC (Registro Único de Contribuyentes) registration for natural persons was the strongest candidate found: a genuine official request-form template (Formato solicitudes RUC inscripcion- persona natural.docx) hosted directly on www.sri.gob.ec, corroborated by SRI's own official screenshot-driven step-by-step guide (GUIA RUC EN LINEA.pdf) for the fully online channel. This document authors that candidate, opening Ecuador's Business Formation vertical (2 of 6).

Sources examined

Primary source

• Authority: Servicio de Rentas Internas (SRI)
• Document: Solicitud de Inscripción del RUC (persona natural) — "Formato solicitudes RUC inscripcion- persona natural.docx"
• URL (directly retrieved, HTTP 200, application/vnd.openxmlformats-officedocument.wordprocessingml.document): https://www.sri.gob.ec/o/sri-portlet-biblioteca-alfresco-internet/descargar/057da380-7223-4000-9e43-fd44c2550cd6/Formato%20solicitudes%20RUC%20inscripcion-%20persona%20natural.docx

• Extraction method: the .docx container is a ZIP archive; word/document.xml was read directly with Python's zipfile module and its <w:tbl> elements walked cell-by-cell via regex over the raw WordprocessingML (no docx-to-plain-text conversion, which would have lost the table's row/column structure). This confirmed 3 tables: The document's preamble (outside any table) reads: "Yo, ___, identificado con cédula/pasaporte No. ___, solicito la inscripción en el Registro Único de Contribuyentes (RUC), para el desarrollo de la(s) siguiente(s) actividad(es) económica(s):", followed by the closing declaration: "Declaro que todos los documentos presentados ante el Servicio de Rentas Internas son auténticos y verdaderos, y me hago responsable de los mismos dentro de los controles posteriores que la Administración Tributaria pueda realizar." and a note that a supporting document ("Documento que respalda la inscripción solicitada, de acuerdo a los requisitos publicados...") must be attached in PDF format.
  1. "Actividad Solicitada" — 4 rows: a header row ("Código CIIU" / "Descripción" / "Señale una de las actividades como principal") and 3 identically-structured data rows, each an empty Código-CIIU cell paired with an empty Descripción cell.
  2. Address block — 14 rows: a two-column header ("DIRECCIÓN DEL DOMICILIO" / "DIRECCIÓN DEL ESTABLECIMIENTO MATRIZ") followed by 13 rows, each a label/blank pair repeated for both address columns: Provincia:, Cantón:, Parroquia:, Calle principal:, Número:, Intersección:, Edificio:, Piso:, Oficina o local:, Referencia de Ubicación:, Teléfono convencional:, Celular:, *Correo electrónico: — 9 of the 13 carry the template's own leading asterisk, 4 do not.
  3. Estimated annual income — a single-cell question, "¿Cuál es el ingreso bruto anual que estima recibir por la actividad que realiza? $ ___".
• Provenance corroboration: docProps/core.xml records the document's author as an identified SRI staff member and a creation timestamp of 2022-08-17T17:45:00Z; word/header1.xml prints "Solicitudes del RUC" as the running page header — both consistent with a genuine internal SRI template rather than a third-party facsimile.

Corroborating source

• Document: "GUIA Inscripción de RUC — Guía para contribuyentes, Inscripción de RUC en Línea" (14 pages)
• URL (directly retrieved, HTTP 200, application/pdf): https://www.sri.gob.ec/o/sri-portlet-biblioteca-alfresco-internet/descargar/399ecb4a-1b47-4f68-99f8-57c96fc67dc5/GUIA%20RUC%20EN%20LINEA.pdf
• File identity: sha256:a94f767fb26d1f79862e8049678b704711ddc6f2373ff78286a6e91cc199757f, 1,044,290 bytes.
• Extraction method: pdfjs-dist (legacy build), getTextContent() per page.
• What it corroborates: the same field set (contact details, address including a "CUEN" electrical-supply-code lookup aid, economic activities via CIIU codes, estimated annual income) appears in this screenshot-driven walkthrough of the fully online SRI en Línea self-service channel, which requires an already-issued online-access password (clave de acceso a SRI en Línea) to reach — this schema does not model that login-gated wizard directly, only the requirement structure it documents in common with the primary .docx template. It also states (p.8) that the annual-income field "debe ser llenado de manera obligatoria" (must be filled in as mandatory) for every applicant, used to justify required: true on ingresoBrutoAnualEstimado despite the primary template printing no asterisk there; and (p.9) a hard cap of "mínimo 1 y máximo 20 actividades económicas por cada establecimiento" for the online channel specifically — disclosed as an online-only detail this schema's 3-slot economic-activity group (matching the primary template's own 3 printed rows) does not reflect.
• Two SRI-published trámite-guide pages on the government's own gob.ec portal were also fetched and read in full this cycle: gob.ec/sri/tramites/inscripcion-registro-unico-contribuyente-ruc-persona-natural and its -documento-habilitante sibling (for applicants in specific regulated professions/segments — accountants, notaries, artisans, transportistas, etc., a narrower sub-case not modelled separately here). Both list the same required-document categories the primary template's own closing note describes (a supporting document per the requisitos ficha), corroborating rather than contradicting the primary source.

External reference table

• CIIU (Clasificación Industrial Internacional Uniforme) code format: confirmed via INEC's own live Sistema Integrado de Consultas de Clasificaciones y Nomenclaturas (aplicaciones2.ecuadorencifras.gob.ec/SIN/), which resolves real codes in the shape [A-U][0-9]{4} with an optional .NN decimal sub-code (e.g. G4711, G4711.01, G4711.02 all resolve as genuine codes). Modelled as a pattern-validated free-text field per this registry's established convention for large external code tables (the full CIIU nomenclature runs to several hundred codes across all sectors), the same approach pe/sunat/solicitud-inscripcion-ruc-persona-natural already uses for its own CIIU fields.

Known gaps / disclosed scope boundaries

• Online-wizard-only conditional logic (RIMPE regime classification derived from declared income, professional-title/artisan-qualification selection changing available CIIU activities, conditional VAT-withholding question) is documented in GUIA RUC EN LINEA.pdf but not modelled here — it belongs to the login-gated SRI en Línea wizard, not the printed request template this schema is built from. A future companion/minor- version cycle that can walk that wizard live (with a real or test-provisioned SRI online-access credential) could extend this schema.
• Economic-activity cap: modelled at 3 slots (matching the primary template's own 3 printed rows), not the online channel's stated 20-per- establishment maximum — disclosed above, consistent with this registry's established bounded-repeating-group convention.
• Ecuador's "Duplicado de cédula Express" National ID candidate (apps.registrocivil.gob.ec/portalCiudadano/cedulaexpress/) remains a disclosed, open, thin lead for a future cycle: live, unauthenticated, confirmed via both direct curl and a real Playwright/Chromium session, but gated after its 3-field search step (cédula number, date of birth, CAPTCHA) by a server-rendered next step this cycle could not reach without a real citizen's own registered identity to search against.
• Ecuador's remaining verticals — Passport, DMV, Taxes, and National ID — are still open backlog candidates after this cycle.

Conformance fixtures

8 fixtures are committed under conformance/ec/sri/inscripcion-ruc-persona-natural/1.0.0/: 2 valid submissions (0 errors each — one single-activity applicant, one multi-activity applicant with a marked principal activity) and 6 mutation-control fixtures (each expected to raise exactly 1 error): a missing required address field (domicilioProvincia), a missing required contact field (domicilioCorreoElectronico), an invalid email format, a missing required applicantFullName, an invalid CIIU-code pattern, and an exclusivityGroups violation (two economic activities both marked principal). All 8 were checked with a from-scratch, throwaway Node mock validator implementing this schema's own required/validation/ exclusivityGroups rules (not committed — consistent with this registry's established per-cycle practice of writing an independent validator rather than reusing the authoring script). Both tools/validate.mjs and tools/validate-ajv.mjs pass at 507/507 across the full registry with this schema added.

Verification method assessment

manual-source-review-v1 — a human/agent read the primary source directly and transcribed its fields. No automated re-verification tooling exists yet for this schema; nextReviewBy is set 6 months out per the practice's default cadence.
