National Identification Number (NIN) Enrolment Form (v2.0)

Nigeria's pre-enrolment form for the National Identification Number (NIN), published by the National Identity Management Commission (NIMC) and completed by an applicant before attending an NIMC enrolment centre in person for biometric capture (fingerprints and facial image). Covers the applicant's names and any prior name change, residence and homelessness status, date/place of birth, place of origin (the applicant's own, and their father's and mother's), physical features and any disability, residence status and nationality, requested card type and issuing bank, an existing-NIN field used only for personal-data-update requests, up to 9 optional supporting identity documents (with document number and expiry date each), marital status, languages, education, religion, occupation, employment status, card home-delivery preference, contact details, both parents' particulars (including each parent's NIN if available), guardian details, next of kin and their address, and the applicant's declaration/attestation. Opens Nigeria's National ID & Civic Documents vertical (Nigeria now stands at 4 of 6 verticals: Business Formation, Taxes, Visa, National ID). This schema models the pre-enrolment form itself, which is the genuine, complete, unauthenticated, field-by-field specimen; it does not and cannot submit the in-person biometric-capture step, which is always required and for which the live NIMC channel (nimc.gov.ng) or an NIMC enrolment centre is authoritative. GovSchema is independent and is not affiliated with, endorsed by, or operated by the Federal Republic of Nigeria or the National Identity Management Commission.

This is GovSchema Standard Research cycle GOV-2569 (child of GOV-2567). It closes Nigeria's National ID & Civic Documents vertical, sourced from the National Identity Management Commission's (NIMC) "National Identification Number (NIN) Enrolment Form", v2.0 — the pre-enrolment form an applicant completes before attending an NIMC enrolment centre in person for biometric capture.

Sources examined

Source 1 — the PDF itself (chosen as source.url)
NIMC's own domain no longer serves this document — disclosed, not a dead end
  • The scouting pass for this cycle (a subagent search under GOV-2567) found that NIMC's own historical static path (nimc.gov.ng/docs/reports/enrolment_form_v2.pdf and sibling paths) now returns NIMC's redesigned React SPA shell / 404, not the PDF. A Wayback Machine CDX check (reported by the scouting pass, not independently re-run in this write-up) shows the direct PDF resolved from 2016 through late 2023, then began returning the SPA shell from 2024 onward — consistent with a 2024 site redesign, not a withdrawal of the underlying form. The Bern-embassy mirror is an official .gov.ng-domain copy of the identical NIMC document (same "v2.0" watermark printed on the form itself), used here as source.url since it is the reachable official copy, following this registry's established practice of citing the best reachable official-domain mirror when a primary agency domain's static path has moved (cf. ng/nis's embassy-mirror sourcing last cycle, GOV-2561).
  • Two other Nigerian-embassy paths for the same form (Nigeria's Washington DC and London missions) were checked opportunistically during this schema's authoring and returned the same v2.0 form byte-for-byte (sha256 matched the Bern copy), corroborating rather than contradicting the primary source, but are not separately cited as a second source.url per this registry's single-source convention.
Source 2 — direct pdfjs-dist text-layer extraction (own re-derivation)
  • This specimen carries zero AcroForm widgets — confirmed via page.getAnnotations() returning an empty array on both of the document's 2 pages — a flat, print-and-hand-fill form, the same tier as this registry's rw/dgie, ng/nis, and ng/firs specimens (no Widget/FT objects to derive field names, charLimits, or radio structure from, unlike the AcroForm-backed gh/nia specimen).
  • Full-page getTextContent() was extracted with each item's transform matrix (x/y in PDF space) preserved, then grouped by rounded y-coordinate into printed lines and cross-checked against every literal "*" glyph's own (x, y) position to determine, field by field, which of the form's ~110 printed blanks/checkboxes the form itself marks mandatory. The form's own footer instruction, printed on both pages, is unambiguous: **"ALL FIELDS MARKED * MUST BE FILLED."**
  • 18 lettered sections (A–R) were identified from the section-heading glyphs (each printed as an isolated single capital letter at a fixed right-margin x-coordinate, e.g. x≈481–503) and used directly as this schema's sourceRef section labels.

Field inventory and scoping/disclosure decisions

  • 104 fields[] + 1 documents[] entry, covering all 18 sections. Enum-shaped printed checkbox groups with named candidate values (e.g. Title, Marital Status, Education Level, Religion, Employment Status, Residence Status, Date of Birth Verification, Home Delivery Yes/No) are each modelled as a single enum field, per this registry's established Nigeria-vertical convention (ng/nis's sex/maritalStatus/ numberOfEntriesRequired fields), rather than N-boolean-plus- exclusivityGroups (the convention gh/nia used for a different jurisdiction's AcroForm checkbox groups) — the source form's own printed candidate lists make the enum boundary directly readable without needing AcroForm widget evidence.
  • Non-exclusive checkbox groups — Section H's physical-marks row (Tribal Marks / Hunch Back / Visible Scars / Others) and Section I's physical-challenges row (Blind / Deaf / Dumb / Paralyzed / Others) — are each modelled as N independent optional booleans, not an enum or exclusivityGroups group, since an applicant can plausibly have more than one mark or challenge simultaneously; no exclusivityGroups entry is declared for either group (disclosed here rather than silently omitted).
  • isHomeless gates the five residence-address fields (townCityOfResidence, countryOfResidence, stateOfResidence, lgaOfResidence, addressOfResidence) via requiredWhen: {field: "isHomeless", equals: "no"} — a disclosed inference from the form's own printed "IF NO, WHERE DO YOU LIVE?" instruction, since the form prints a * on each address field unconditionally (no separate "if no" marking distinguishes the two Yes/No branches in the raw asterisk layer). residencePostalCode remains unconditionally optional (no asterisk on either branch).
  • Section B (previous name) carries no Yes/No checkbox of its own — only a section heading ("HAVE YOU CHANGED YOUR NAME BEFORE?") followed directly by three blanks, none asterisked. Modelled as three independently optional fields with no gating condition, since no boolean trigger exists on the form to condition on.
  • Section K (existing NIN, "FOR APPLICANT'S PERSONAL DATA UPDATE ONLY") carries no asterisk and is modelled as an unconditionally optional field, disclosed in its own description as applicable only to the update use case rather than first-time enrolment; the form provides no separate boolean distinguishing "first enrolment" from "update" requests to gate it on.
  • Section O (Guardian Details) prints * on Surname, First Name, and National Identification Number (not Middle Name) with no separate toggle distinguishing a minor/dependent applicant (who would plausibly need a guardian) from an adult self-enrolling applicant. This schema takes the form's asterisks at face value — guardianSurname, guardianFirstName, and guardianNin are modelled required: true unconditionally — following the form's own blanket "ALL FIELDS MARKED MUST BE FILLED" instruction rather than inferring an unstated conditional trigger the source does not print. This is flagged explicitly as a disclosed judgment call, not a silent pass-through: a future review with access to NIMC's own internal completion guidance could reasonably revise this to a conditional (e.g. gated on an applicant-is-a-minor signal this form does not itself carry).
  • Section L (Supporting Documents) — 9 named document types (Any Identity Reference, Immigration Document, National Insurance, Nigeria Driver Licence, Nigerian Passport, Other Designated Document, Other National Identity Card, Other Passport, Other Travel Document), each with a Document Number and Document Expiry Date blank, none asterisked. Modelled as 18 independently optional fields[] entries (not documents[]) since each captures structured data (a number and a date) rather than a simple provided/not-provided attachment flag — consistent with how this registry models identity-document-number fields elsewhere (cf. gh/nia's institutional-ID fields) rather than as documents[] entries, which are reserved here for the form's actual attestation.
  • No maxLength values are derived from AcroForm charLimit (unlike gh/nia), because this specimen has no AcroForm at all. Free-text maxLength values are round-number estimates in the same spirit as this registry's other flat-form schemas (ng/nis's 100–200-character estimates), not a structural fact — disclosed here rather than presented as source-derived.
  • NIN-number fields (existingNin, fathersNin, mothersNin, guardianNin, nextOfKinNin) are modelled as plain strings with a generous maxLength: 20 and no digit-only pattern. Nigeria's NIN is widely documented elsewhere as an 11-digit number, but this specimen itself prints no character-count guide on these blanks, so no pattern constraint is asserted from this source — a deliberate choice not to import an external fact the form itself does not state.
  • applicantDeclaration (documents[], category attestation) quotes the form's own certification paragraph verbatim, including its citation of "the NIMC Act 23 of 2007," confirmed still in force via a fresh web search (NIMC continues to describe itself, and to be described in current reporting, as operating under the National Identity Management Commission Act No. 23 of 2007).
  • No documents[] entry models the raw signature/thumbprint capture — the source prints only a dotted signature line (this is a flat, non-AcroForm PDF, so there is no capture widget to exclude in the first place); signatureDate is modelled as a required date field instead, consistent with this registry's general practice of not modelling raw biometric/signature capture as a schema field.

Conformance run

Two valid fixtures were built against schema.json with a from-scratch, ajv-free checker script (evaluates required/requiredWhen with visibility gating, per-type validation keywords, and documents[] required/requiredWhen directly against the meta-schema's own rules) — not any author-provided tooling, since no shared tools/conformance-runner.mjs exists yet in this repo:

  • single-adult-first-time-enrolment-not-homeless.json — an unmarried female Nigerian applicant, not homeless (exercising the isHomeless-gated requiredWhen branch that requires residence-address fields), first-time enrolment (no existingNin). 0 errors.
  • married-personal-data-update-with-supporting-document.json — a married male applicant with a prior name change (Section B), a personal-data-update request (existingNin populated), a Nigerian Passport supporting document (Section L), a tribal mark and a paralysis physical challenge (exercising the independent, non-exclusive checkbox fields), and homeless (exercising the opposite isHomeless branch, where residence-address fields are correctly not required). 0 errors.

Five mutation-control fixtures, each a single deliberate violation of the first valid fixture, each correctly raised exactly 1 error:

  • mutation-control-missing-required-field.json — removes lastname (required) → 1 error.
  • mutation-control-invalid-date-format.json — sets dateOfBirth to "14-03-1998" (not YYYY-MM-DD) → 1 error.
  • mutation-control-invalid-enum-value.json — sets gender to "X" (not in the ["M","F"] enum) → 1 error.
  • mutation-control-missing-conditional-field.json — removes townCityOfResidence while isHomeless remains "no" → 1 error (requiredWhen violation).
  • mutation-control-missing-required-document.json — omits the applicantDeclaration document → 1 error.

node tools/validate.mjs and node tools/validate-ajv.mjs (JSON Schema draft 2020-12 meta-schema conformance) both pass clean for registry/ng/nimc/nin-enrolment-form/1.0.0/schema.json.

Backlog note

Nigeria now stands at 4 of 6 verticals (Business Formation, Taxes, Visa, National ID). DMV was confirmed a dead end in a prior cycle (GOV-2561: FRSC state licensing is SSO-portal-gated with no downloadable specimen). Passport remains the sole open backlog vertical — this cycle's scouting also identified a strong candidate, NIS "Form C1" (Application for Nigeria Standard Passport), reachable unauthenticated via the Nigeria High Commission London's own mirror (nigeriahc.org.uk/wp-content/uploads/2023/05/LostReqForm.pdf, ~35–40 fields plus a guarantor's Form of Undertaking), left for a future cycle. Rwanda's Business Formation vertical (RDB "RF-001 Domestic Company Application for Incorporation", businessprocedures.rdb.rw/media/2.5_rf-001%20domestic%20company.pdf, 18 numbered sections) was also scouted this cycle as a strong candidate and left open for a future cycle.
