Standardize Phone Number

Normalizes a phone number to E.164 international format. If the dialr package is installed, supports all countries via Google's libphonenumber. Otherwise, falls back to built-in NZ/AU rules.

Usage

ac_standardize_phone(phone, default_region = "NZ")

Arguments

phone

A character vector of phone numbers

default_region

ISO 3166-1 alpha-2 country code assumed for numbers without a country prefix (default: "NZ")

Value

A character vector of E.164 formatted phone strings (e.g., "+6421234567"), or NA_character_ for unparseable numbers

Examples

ac_standardize_phone("021 123 4567")          # "+6421234567"
#> [1] "+64211234567"
ac_standardize_phone("+64211234567")           # "+64211234567"
