Validate Iranian mobile numbers, normalize between formats (`0...`, `+98...`, `0098...`), extract the 4-digit operator prefix, and look up operator name plus province coverage. Use when validating SMS gateway input, building contact forms, or showing operator info next to a number. Triggers on mentions of isPhoneNumberValid, phoneNumberDetail, phoneNumberNormalizer, getPhoneNumberPrefix, ایرانسل, همراه اول, mobile validation, +98.

phoneNumber — Iranian mobile number tooling

import {
  phoneNumberDetail,
  isPhoneNumberValid,
  phoneNumberNormalizer,
  getPhoneNumberPrefix,
} from "@persian-tools/persian-tools";
// CommonJS
const {
  phoneNumberDetail,
  isPhoneNumberValid,
  phoneNumberNormalizer,
  getPhoneNumberPrefix,
} = require("@persian-tools/persian-tools");

Public exports

phoneNumberDetail(mobile: string): OperatorModel | null
isPhoneNumberValid(mobile: string): boolean
phoneNumberNormalizer(phoneNumber: string, token: "0" | "+98"): string
getPhoneNumberPrefix(mobile: string): string

interface OperatorModel {
  province: string[];           // provinces this prefix covers
  base: string;                 // home province
  type: ("permanent" | "credit")[];   // SIM type(s) available
  operator: { id: number; name: string; ... };   // operator metadata
  model?: string;
}

The exported validator is isPhoneNumberValid, not validatePhoneNumber. The operator-detail function is phoneNumberDetail, not getPhoneOperator.

isPhoneNumberValid

import { isPhoneNumberValid } from "@persian-tools/persian-tools";

isPhoneNumberValid("09123456789");      // true
isPhoneNumberValid("+989123456789");    // true
isPhoneNumberValid("989123456789");     // true
isPhoneNumberValid("00989123456789");   // true
isPhoneNumberValid("9123456789");       // true (bare)
isPhoneNumberValid("0212345678");       // false (landline, not mobile)

Regex: /^(\+98|98|0098|0)?9(\d{2})\d{7}$/. The function additionally checks that the 3-digit operator prefix (9xx) is in the known prefixes list (which excludes unassigned blocks). It only validates mobile, not landlines.

phoneNumberNormalizer

Convert between 0 and +98 representations. Throws if the input doesn't validate.

import { phoneNumberNormalizer } from "@persian-tools/persian-tools";

phoneNumberNormalizer("+989022002580", "0");   // "09022002580"
phoneNumberNormalizer("09022002580", "+98");   // "+989022002580"
phoneNumberNormalizer("989022002580", "0");    // "09022002580"
phoneNumberNormalizer("09802002580", "0");     // throws: "phone number is not valid"

token is exactly "0" | "+98" — no other prefixes supported.

phoneNumberDetail

Look up operator + coverage by the 3-digit operator prefix.

import { phoneNumberDetail } from "@persian-tools/persian-tools";

phoneNumberDetail("09123456789");
// {
//   province: ["البرز", "تهران", ...],
//   base: "تهران",
//   type: ["permanent"],
//   operator: { id: 1, name: "همراه اول", ... },
// }

phoneNumberDetail("09000000000");
// null — prefix "900" not assigned

Don't compare phoneNumberDetail(...) === "همراه اول" — the return is an object. The operator name is result.operator.name.

getPhoneNumberPrefix

Returns the 4-digit operator prefix (including the leading 9) — e.g. "0912" for همراه اول prefixes:

getPhoneNumberPrefix("09123456789");   // "0912"

Useful for grouping numbers in dashboards.

Common pitfalls

  • Validates mobile only. Landlines (021..., 031..., etc.) all return false. There's no landline validator in this module.
  • phoneNumberDetail returns OperatorModel | null — not a string. Older docs claim it returns the operator name directly.
  • phoneNumberNormalizer throws on invalid input. Always isPhoneNumberValid first or wrap in try/catch.
  • Persian/Arabic digit input is NOT normalized. Run autoConvertDigitsToEN first if input may contain them.
  • +98 token includes the +. Don't pass "98" and expect the same result.

Composition pattern for forms

import {
  autoConvertDigitsToEN,
  isPhoneNumberValid,
  phoneNumberNormalizer,
  phoneNumberDetail,
} from "@persian-tools/persian-tools";

function processPhone(raw: string) {
  const norm = autoConvertDigitsToEN(raw.trim());
  if (!isPhoneNumberValid(norm)) return { ok: false as const };
  return {
    ok: true as const,
    e164: phoneNumberNormalizer(norm, "+98"),
    local: phoneNumberNormalizer(norm, "0"),
    detail: phoneNumberDetail(norm),
  };
}
