Features

Phone Number Normalization

An extensible normalizier allows you to normalize the phone number into a standardized format you want. The default out of the box provides

• Trimming whit spaces, dashes, and decimals
• Converting to English numbers
• Replacing and standardizing to 09

val input = "+၉၅၉၇၈၄၁၂၃၄၅၆"
val normalizer = MyanmarPhoneNumberNormalizer()
val result = normalizer.normalize(input)
print(result) //: 09784123456

Custom Rules

You can also use the builder provided to add custom rules. This allows you to create your own standardized format such as using "+959" instead of "09", or converting other languages to English numerals etc.

class NineFiveNineRule : Rule {
  private val possibleCases = Regex("(09-)|(\\+959)|(09\\s)|(959)|(09\\.)")
  
  override fun convert(input: String): String {
    if (possibleCases.containsMatchIn(input)) {
      return input.replaceFirst(possibleCases, "+959")
    }
    return input
  }
  
}

val builder = MyanmarPhoneNumberNormalizer.Builder()
builder.addRule(NineFiveNineRule())

val input = "09784123456"

val output = builder.build().normalize(input)

print(output) //+959784123456

Phone number Validaiton

Check whether a phone number is a valid Myanmar phone number

MyanmarPhoneNumberUtils.isValidMyanmarPhoneNumber("09978412345") //true
MyanmarPhoneNumberUtils.isValidMyanmarPhoneNumber("14155552671") //false

Opreator Checking

Check which opreator the number is from

MyanmarPhoneNumberUtils.getTelecomOperator("09958412345") //Ooredoo
MyanmarPhoneNumberUtils.getTelecomOperator("09784123456") //Telenor
MyanmarPhoneNumberUtils.getTelecomOperator("09420012345") //MPT
MyanmarPhoneNumberUtils.getTelecomOperator("09690000966") //MyTel

Network Type Checking

Check which network the numer belongs to

MyanmarPhoneNumberUtils.getNetworkType("09978412345") //GSM
MyanmarPhoneNumberUtils.getNetworkType("09451212123") //WCDMA
MyanmarPhoneNumberUtils.getNetworkType("096355555") //CDMA 450Hz
MyanmarPhoneNumberUtils.getNetworkType("0973123456") //CDMA 800Hz

val extractor = MyanmarPhoneNumberExtractor()
val input = "၀၉၁၂၃၄၅၆၇ (မောင်မောင်)၊ ၀၉၁၂၃၄၅၆၆ (အောင်အောင်)"
val result = extractor.extract(input) //[091234567, 091234566]
