numbering-plan

This library helps you migrate exiting phone numbers format to new phone number formats.

Usage

First you start by defining the migration rules for you country

val ivoryCoastPlanFactory: CountryPlan = CountryPlan.Builder()
    .setOldPhoneNumberSize(8)
    .setInternationalCallingCode("225")
    .setDigitMapperPosition(Position.START) // Position.END
    .setMigrationType(MigrationType.PREFIX) // MigrationType.POSTFIX
    .setPrefixesMapper(
      mapOf(
        "07" to "07", // Orange
        "08" to "07", // eg: 08 XX XX XX => 07 08 XX XX XX (if MigrationType.prefix is used) => 08 XX XX XX 07 (if MigrationType.postfix is used)
        "09" to "07",
        "04" to "05", // MTN
        "05" to "05",
        "06" to "05",
        "01" to "01", // MOOV
        "02" to "01",
        "03" to "01"
      )
    ).build()

Then you pass those rules to NumberingPlan and you can start the migration:

val ivoryCoastPlanFactory: CountryPlan = ...
val numberingPlan = NumberingPlan(ivoryCoastPlanFactory)
val newPhoneNumbers = numberingPlan.migrate(mapOf(
  "userId-1" to listOf("08060709"),
  "userId-2" to listOf("06060709"),
  "userId-6" to listOf("zezae/03-060-701", "01020304"),
  "userId-3" to listOf("03060701"),
  "userId-4" to listOf(" 03 060 701 "),
  "userId-5" to listOf(" 03-060-701"),
  "userId-7" to listOf(")'.03-060-701")
))

After the migration newPhoneNumbers will be equal to:

mapOf(
  "userId-1" to listOf("002250708060709"),
  "userId-2" to listOf("002250506060709"),
  "userId-6" to listOf("", "002250101020304"),
  "userId-3" to listOf("002250103060701"),
  "userId-4" to listOf("002250103060701"),
  "userId-5" to listOf("002250103060701"),
  "userId-7" to listOf("")
)

Invalid phone numbers are replaced by empty string.

Known limitations

• Migrates only valid phone numbers.
• Can add new digits before or after the old phone number. We decided to not handle in between insertions.
• Can only look for digits to replace at the start, or the end of old phone numbers. We think this shouldn’t be a problem (generally) but as of now we decided to not handle such cases.
• It is synchronous. This is a choice that will let you pick the any library you want to handle async tasks.
