octopos-ve-documents

Venezuelan identity documents (cédula, RIF, passport) for the octoPOS ecosystem: validation, mod-11 check digit, formatting, input masks and per-type placeholder examples. Zero runtime dependencies, dual ESM + CJS, TypeScript types included.

This package is the cross-repo single source of truth for the octoPOS Venezuelan identity-document standard (owner ruling 2026-07-16). The octoPOS repos (admin, pos, platform, web) consume it through thin per-repo shims.

The standard

• Cédula (person identity): V|E + 6–8 digits, stored zero-padded to 8; display V-01234567. 9 digits is NEVER a cédula.
• RIF (fiscal tax id): V E J P G C + 9 digits (8 body + 1 final digit); display J-12345678-9. Validation is format and length only (owner ruling 2026-07-18): SENIAT never officially published the check-digit algorithm and legitimately issued RIFs exist that do not match the public variant, so the mod-11 arithmetic (rifCheckDigit, prefix values {V:1,E:2,J:3,C:3,P:4,G:5}×4 + body weights [3,2,7,6,5,4,3,2], digit = 11 − (sum mod 11), → 0 when ≥ 10) is exposed as an informational utility — used e.g. to generate realistic placeholder examples — never as a write gate. Document legitimacy is verified by human review of the RIF certificate.
• Passport (person identity, type P): ^[A-Z0-9]{5,15}$ — person contexts only, never a fiscal tax number.

Storage and API contracts always carry the split pair (fiscal taxType+taxNumber, person idDocumentType+idDocument); the composed dashed string is display-only.

Install

npm install octopos-ve-documents

API

Split-pair (type letter + digits)

import { classifyTaxId, formatTaxId, isValidTaxId, rifCheckDigit } from "octopos-ve-documents";

classifyTaxId("V-1234567");   // { type: "V", number: "01234567", kind: "cedula" }
classifyTaxId("123456784");   // { type: "J", number: "123456784", kind: "rif" }
isValidTaxId("J-12345678-4"); // true (structure/length only)
formatTaxId("J", "123456784"); // "J-12345678-4"
rifCheckDigit("J", "123456780"); // 4 — informational mod-11 utility, never a gate

Composed-string (parse/compose canonical J-12345678-9 / V-01234567)

import { composeTaxId, composeTaxIdStrict, parseTaxId, validateRif } from "octopos-ve-documents";

parseTaxId("J-12345678-4");           // { type: "J", number: "123456784" } — structure-only
parseTaxId("J-12345678-9", { requireCheckDigit: true }); // null — opt-in mod-11 screening (informational)
composeTaxId("V", "1234567");         // "V-01234567" (loose: null on bad parts, never throws)
composeTaxIdStrict("J", "123456784"); // "J-12345678-4" (throws on structural problems only)
validateRif("J-12345678-4");          // true (format/length)

Input metadata (placeholders & masks)

import { documentInputRules, sanitizeDocumentInput, taxIdExample } from "octopos-ve-documents";

taxIdExample("V", "person");  // "12345678"
taxIdExample("P", "person");  // "AB123456"
taxIdExample("J", "fiscal");  // "301420608" — check digit computed, valid by construction
documentInputRules("P", "person"); // { alphanumeric: true, maxLength: 15, inputMode: "text" }
sanitizeDocumentInput("V", "12.345.678", "person"); // "12345678"

Testing

The suite pins the canonical cross-repo mod-11 vectors for the informational rifCheckDigit utility — matching: V-12345678-1 E-12345678-8 J-12345678-4 C-12345678-4 P-12345678-0 G-12345678-7 J-30142060-8; non-matching: V-12345678-9 E-12345678-0 J-12345678-9 C-12345678-5 P-12345678-1 G-12345678-1. (Validation gates accept both sets — they check format/length only.)
