An anthology of tools for working with Persian (Iranian) data in Go.

No dependencies. The module's go.mod lists nothing, and there is no go.sum. Everything here is the standard library and this repository.

Packages

Package	What it does
text	Normalize Persian text, fold Arabic look-alikes, fix keyboard layouts, romanize
digit	Convert digit sets, group and spell numbers, format Toman and Rial
bank	Validate card numbers (Luhn), resolve banks, validate Sheba (IBAN) codes
nationalid	Validate national numbers (code-e Melli), resolve city and province
phonenumbers	Validate Iranian mobiles, normalize prefixes, resolve operators

Install

go get github.com/amiranmanesh/go-persian-tools@latest

Requires Go 1.22+. Import only the sub-packages you need.

Usage

text

import "github.com/amiranmanesh/go-persian-tools/text"

// Fold Arabic look-alikes so text compares reliably.
text.FixArabic("علي كريم")  // علی کریم
text.Normalize("مقالهٔ من") // مقاله من  (idempotent: safe to apply twice)

// Recover text typed on the wrong keyboard layout.
text.SwitchToPersianKey("sghl") // سلام
text.SwitchToEnglishKey("اثغ")  // hey

text.Finglish("سلام")           // salam
text.Reverse("سلام")            // مالس
text.CheckIsEnglish("ali")      // true
text.OnlyPersianAlpha("123شاهینhi") // شاهین

Normalize is meant for comparison keys, not display: it folds alef and hamza variants, drops vocalization marks, and turns zero-width joiners into spaces. Keep the original for showing back to the user.

digit

import "github.com/amiranmanesh/go-persian-tools/digit"

// Digit sets — Persian, Arabic-Indic and ASCII.
digit.ToPersianDigits("123salam456")   // ۱۲۳salam۴۵۶
digit.ToEnglishDigits("۰۹۱۲٣٤٥٦٧٨٩")   // 09123456789
digit.OnlyNumbers("شماره: 0912-345")   // 0912345

// Grouping and words.
digit.AddCommas(14555478854)            // 14,555,478,854
n, err := digit.RemoveCommas("۱۲۳،۴۵۶") // 123456
digit.ToWords(156789)                   // صد و پنجاه و شش هزار و هفتصد و هشتاد و نه
digit.ToWord("-10")                     // منفی ده

// Money.
digit.Currency("1234567") // ۱،۲۳۴،۵۶۷
digit.Toman("1234567")    // ۱،۲۳۴،۵۶۷ تومان
digit.Rial("1234567")     // ۱،۲۳۴،۵۶۷ ﷼

bank

import "github.com/amiranmanesh/go-persian-tools/bank"

name, err := bank.CardInfo("6037701689095443") // "keshavarzi", nil
// errors.Is(err, bank.ErrInvalidCard) / bank.ErrBankNotFound

sheba := bank.ShebaCode{Code: "IR820540102680020817909002"}
if sheba.IsValid() {
    info := sheba.IsSheba()
    fmt.Println(info.Name, info.PersianName) // Parsian Bank بانک پارسیان
}

nationalid

import "github.com/amiranmanesh/go-persian-tools/nationalid"

nationalid.Validate("0067749828") // true

place := nationalid.GetPlaceByIranNationalID("0499370899")
fmt.Println(place.City, place.Province) // شهرری تهران

phonenumbers

import "github.com/amiranmanesh/go-persian-tools/phonenumbers"

phonenumbers.IsPhoneValid("09122221811") // true

details, err := phonenumbers.GetPhoneDetails("09123456789")
if err == nil {
    fmt.Println(details.GetOperator()) // MCI
}

phonenumbers.PhoneNumberNormalizer("09122221811", "+98") // +989122221811

bill

import "github.com/amiranmanesh/go-persian-tools/bill"

params := bill.Params{BillID: 1117753200140, PaymentID: 12070160}

bill.GetBillType(params)  // تلفن ثابت
bill.GetCurrency(params)  // 120000
bill.GetBarCode(params)   // 111775320014000012070160
bill.VerifyBillID(params) // true

Command line

Every package is also reachable from one binary, usable as a one-off or as a pipeline filter:

go install github.com/amiranmanesh/go-persian-tools/cmd/persian-tools@latest

persian-tools normalize "علي كريم"          # علی کریم
persian-tools words 156789                   # صد و پنجاه و شش هزار و هفتصد و هشتاد و نه
persian-tools currency -unit toman 1234567   # ۱،۲۳۴،۵۶۷ تومان
persian-tools key-to-persian sghl            # سلام
persian-tools national-id 0067749828         # true   (exit 0; invalid exits 1)
persian-tools sheba IR820540102680020817909002

cat names.txt | persian-tools normalize > keys.txt

Or without installing anything:

docker run --rm ghcr.io/amiranmanesh/go-persian-tools:latest normalize "علي كريم"

Prebuilt binaries for Linux, macOS and Windows are attached to every release.
