@munesoft/phonex

The AI-first phone number validation, parsing, and intelligence library for JavaScript & TypeScript. Faster, smarter, and more powerful than traditional solutions like libphonenumber-js.

🚀 Why Phonex?

Most libraries only parse phone numbers.

Phonex goes further:

• ◆✅ Validate phone numbers (lenient, strict, AI modes)
• ◆✅ Format international & national numbers
• ◆✅ Detect country, carrier, and number type
• ◆✅ Identify spam, fake, and reserved test numbers
• ◆✅ Optimize SMS / WhatsApp / OTP delivery
• ◆✅ Power AI agents with structured phone intelligence
• ◆✅ Zero runtime dependencies, works in Node.js, browsers, and edge runtimes (Cloudflare Workers, Vercel Edge, Deno)

⚡ Install

npm install @munesoft/phonex

yarn add @munesoft/phonex

pnpm add @munesoft/phonex

🧠 One-Line Usage

import phonex from "@munesoft/phonex";

const phone = phonex("+254712345678");

console.log(phone.valid);          // true
console.log(phone.country);        // "KE"
console.log(phone.countryCallingCode); // "254"
console.log(phone.national);       // "712345678"
console.log(phone.international);  // "+254 712 345678"
console.log(phone.e164);           // "+254712345678"
console.log(phone.type);           // "mobile"
console.log(phone.carrier);        // "Safaricom"
console.log(phone.timezone);       // "Africa/Nairobi"
console.log(phone.risk);           // { score: 0, level: "low", flags: [] }

CommonJS works too:

const phonex = require("@munesoft/phonex");
phonex("+254712345678");

🔥 Features

📞 Phone Number Validation (Best-in-Class)

Three validation levels for different stages of your funnel:

import { validate } from "@munesoft/phonex/validate";

// Lenient: fast length-based check, ITU-T E.164 compliant.
// Use during signup so you don't reject borderline-valid international numbers.
validate("+254712345678", { level: "lenient" });

// Strict: full per-country regex validation.
// Use for KYC, billing, OTP delivery.
validate("+254712345678", { level: "strict" });

// AI: strict + anomaly detection (sequential digits, low-entropy, test ranges).
// Returns confidence score + list of anomalies. Use for fraud detection.
validate("+254712345678", { level: "ai" });
// → { valid, possible, confidence: 0.95, anomalies: [], ... }

🌍 Country Detection

phonex.detect("+447911123456");   // "GB"
phonex.detect("0712345678", { country: "KE" });  // "KE"

🔄 Normalize Phone Numbers

Turn any messy input into clean E.164:

phonex.normalize("07 12-345-678", { country: "KE" });
// "+254712345678"

phonex.normalize("+254 712.345.678");
// "+254712345678"

⚡ Format Phone Numbers

const phone = phonex("+254712345678");

phone.formatInternational();  // "+254 712 345678"
phone.formatNational();       // "712345678"
phone.e164;                   // "+254712345678"

🧠 AI Mode (Perfect for AI Agents & LLMs)

phonex("+254712345678", { ai: true });

Returns LLM-friendly structured data with confidence and reasoning:

{
  "valid": true,
  "country": "KE",
  "type": "mobile",
  "carrier": "Safaricom",
  "ai": {
    "confidence": 0.95,
    "reasoning": "identified as KE; type: mobile; carrier: Safaricom; validated against curated metadata for KE",
    "anomalies": []
  }
}

🚨 Risk & Spam Detection

Heuristic detection of fake numbers, test ranges, and patterns commonly seen in fraud:

import { risk } from "@munesoft/phonex/risk";

risk("+254000000000");
// { score: 0.9, level: "high", flags: ["all-identical-digits"] }

risk("+12125550100");
// { score: 0.95, level: "high", flags: ["reserved-test-range"] }

risk("+254712345678");
// { score: 0, level: "low", flags: [] }

Detected signals:

• ◆Repeated digits (0000000000)
• ◆Sequential digits (1234567890, 9876543210)
• ◆Reserved test ranges (NANPA 555-01xx, country-specific test prefixes)
• ◆Low entropy (only 1–3 unique digits)
• ◆Implausible length
• ◆Failed strict validation

📡 Carrier Detection

Curated, accurate carrier mapping for supported regions. Returns null rather than guess for unsupported countries:

phonex.carrier("+254712345678");  // "Safaricom"
phonex.carrier("+254733456789");  // "Airtel Kenya"
phonex.carrier("+2348031234567"); // "MTN Nigeria"
phonex.carrier("+447911123456");  // null (UK carrier prefixes are not stable)

Supported carrier-detection countries: KE, UG, NG, ZA, IN.

🧭 Timezone & Region

import { geo } from "@munesoft/phonex";

geo("+254712345678");
// { country: "KE", callingCode: "254", timezone: "Africa/Nairobi", multiTimezone: false }

geo("+14155552671");
// { country: "US", callingCode: "1", timezone: null, multiTimezone: true }

📲 Multi-Channel Detection

Decide whether SMS, WhatsApp, or voice is appropriate for a number:

phonex.channels("+254712345678");
// { sms: true, whatsapp: true, voice: true }

phonex.channels("+442012345678");
// { sms: false, whatsapp: false, voice: true }   // UK landline

phonex.channels("+8613912345678");
// { sms: true, whatsapp: false, voice: true }    // CN: WhatsApp blocked

Pass ai: true for reasoning on each channel.

✍️ As-You-Type Formatting

Perfect for phone-input UI components:

phonex.input("0", { country: "KE" });          // "0"
phonex.input("0712", { country: "KE" });       // "0712"
phonex.input("0712345678", { country: "KE" }); // "0712 345 678"

phonex.input("4155552671", { country: "US" }); // "415 555 2671"
phonex.input("+254712345678");                 // "+254 712 345 678"

💡 Smart Suggestions

When a number is malformed, suggest plausible fixes:

phonex.suggest("712345678");
// {
//   input: "712345678",
//   suggestions: [
//     { e164: "+254712345678", country: "KE", confidence: 0.65, reason: "valid as KE national number" },
//     ...
//   ]
// }

📊 Bulk Processing

Process thousands of numbers with bounded concurrency:

const results = await phonex.batch(numbers, {
  concurrency: 50,
  country: "KE",
  level: "strict",
  continueOnError: true,
});

Or stream them lazily:

for await (const phone of phonex.stream(numbers)) {
  console.log(phone.country, phone.valid);
}

stream() accepts both Iterable and AsyncIterable — works seamlessly with file streams, fetch responses, generators, and database cursors.

📈 Analytics

Aggregate stats over a list of numbers — perfect for CRM data cleaning, KYC reports, or dashboards:

phonex.analytics(numbers);
// {
//   total: 5000,
//   valid: 4823,
//   invalid: 177,
//   countryDistribution: { KE: 3200, NG: 1100, US: 523 },
//   typeDistribution: { mobile: 4500, landline: 323, voip: 0, tollfree: 0, unknown: 177 },
//   riskDistribution: { low: 4823, medium: 0, high: 177 },
//   topCarriers: [{ carrier: "Safaricom", count: 2400 }, ...]
// }

🔌 Express Middleware

Auto-validate and normalize phone fields in every request:

import express from "express";
import phonex from "@munesoft/phonex";

const app = express();
app.use(express.json());

app.use(phonex.middleware({
  fields: ["phone", "mobileNumber"],   // fields to scan in body/query/params
  country: "KE",                        // default country
  level: "strict",
  reject: true,                         // 400 on invalid; default false
  normalize: true,                      // rewrite valid fields to E.164
}));

app.post("/signup", (req, res) => {
  // req.body.phone is now "+254712345678" (normalized)
  // req._phonex.phone holds the full PhonexResult
  res.json({ ok: true, phone: req.body.phone });
});

Works with any framework using the standard (req, res, next) signature: Express, Connect, Restify, Polka.

🔐 Privacy Mode

Mask or hash numbers for logging and storage:

phonex("+254712345678", { privacy: true });
// e164: "+********5678"

phonex("+254712345678", { privacy: "hash" });
// e164: "phx_a1b2c3d4"     // deterministic hash

Note: privacy: "hash" uses FNV-1a — fast and great for deduplication keys, but not cryptographic. For GDPR / regulatory hashing, use Web Crypto SubtleCrypto.digest in your application layer.

🧵 Streaming Support

for await (const phone of phonex.stream(asyncIterable)) {
  // process one at a time
}

🧩 Plugin System

Extend Phonex with custom logic — third-party data, alternate validation rules, audit logging:

phonex.use({
  name: "twilio-lookup-enrichment",
  onResult(result) {
    // mutate or replace the result
    return result;
  },
});

⚙️ Modular Usage (Tree-Shaking)

Phonex ships with subpath exports so you only pay for what you use:

import { validate } from "@munesoft/phonex/validate";
import { risk } from "@munesoft/phonex/risk";
import { input, suggest, normalize } from "@munesoft/phonex/input";
import { analytics } from "@munesoft/phonex/analytics";
import { middleware } from "@munesoft/phonex/middleware";
import { phonex, parse } from "@munesoft/phonex/core";

Modern bundlers (Vite, esbuild, Rollup, Webpack 5, Parcel 2) will tree-shake unused features automatically. The full bundle is ~40 KB minified before tree-shaking; a typical app importing only validate is well under 20 KB.

🌐 Universal Compatibility

Phonex runs everywhere modern JS runs:

| Runtime | Supported | |---|---| | Node.js ≥ 16 | ✅ | | Modern browsers (ES2020) | ✅ | | Cloudflare Workers | ✅ | | Vercel Edge Runtime | ✅ | | Deno | ✅ | | Bun | ✅ |

No Buffer, no fs, no crypto.randomBytes — Phonex is pure JavaScript with zero runtime dependencies.

⚡ Performance

• ◆⚡ < 1ms typical parse time (cached: ~0.01ms)
• ◆🪶 Zero dependencies
• ◆🔁 Built-in LRU+TTL cache (2000 entries / 10-minute TTL by default)
• ◆🌳 Fully tree-shakable via subpath exports
• ◆📦 ~40 KB full bundle, much less when tree-shaken

Disable the cache for individual calls when needed:

phonex("+254712345678", { noCache: true });
phonex.clearCache();   // wipe the entire cache

🌍 Country Coverage

Phonex includes:

• ◆Full ITU-T E.164 calling code table (200+ countries) — every country can be detected from its calling code.
• ◆Curated strict-validation metadata for 30+ high-traffic countries: KE, US, GB, DE, FR, NG, ZA, IN, BR, CA, AU, JP, CN, MX, ES, IT, NL, RU, SA, AE, EG, GH, UG, TZ, RW, ET, SG, ID, PH, KR, TR.
• ◆For countries outside the curated set, strict mode falls back to length-only validation and flags metadataAvailable: false in the response — so you always know the confidence level.

This is intentional: rather than ship 250 hand-rolled regexes that may be inaccurate, we ship a smaller curated set we've verified, plus a clear honest API for the long tail.

🧠 Use Cases

• ◆Signup & authentication — validate at the form, normalize for storage
• ◆Fintech & KYC — strict-mode validation before money moves
• ◆CRM data cleaning — analytics over messy historical records
• ◆Messaging platforms — pick the right channel (SMS / WhatsApp / voice)
• ◆AI agents & LLM tools — structured phone intelligence with confidence scores
• ◆Fraud detection — flag fake numbers before you spend money on lookup APIs

📘 TypeScript

Full type definitions ship with the package. All public APIs are strictly typed:

import type {
  PhonexResult,
  PhonexOptions,
  ValidationLevel,
  RiskAssessment,
  PhoneType,
  AnalyticsResult,
} from "@munesoft/phonex";

🆚 Comparison

| Feature | @munesoft/phonex | libphonenumber-js | |---|---|---| | Parsing | ✅ | ✅ | | Formatting | ✅ | ✅ | | Strict validation | ✅ | ✅ | | AI / anomaly mode | ✅ | ❌ | | Risk / spam detection | ✅ | ❌ | | Carrier detection | ✅ (curated) | ❌ | | Channel detection (SMS/WhatsApp/voice) | ✅ | ❌ | | Built-in LRU cache | ✅ | ❌ | | Bulk + streaming | ✅ | ❌ | | Suggestions for malformed input | ✅ | ❌ | | Privacy mode (mask / hash) | ✅ | ❌ | | Express middleware | ✅ | ❌ | | Plugin system | ✅ | ❌ | | Country coverage (parsing) | 200+ | 240+ | | Country coverage (strict validation) | 30 (curated) | 240 (autogenerated) | | Bundle size (minified) | ~40 KB | ~145 KB | | Zero dependencies | ✅ | ✅ |

Phonex is not a replacement for libphonenumber-js if you need exhaustive coverage of every country's regulatory metadata. It's the AI-first intelligence layer built for modern apps that care about developer ergonomics, AI compatibility, and feature density over raw country-count metrics.
