Uses the dialvalidator package to
parse and format phone numbers. For numbers without a country code, tries
each region in default_regions in order until a valid parse is found.
Numbers that cannot be parsed as valid in any region are returned as NA.
Usage
standardize_phone(phone, default_regions = c("NZ", "AU"))
Arguments
- phone
A single phone number string.
- default_regions
Character vector of ISO 3166-1 alpha-2 region codes
to try when the number lacks a country code (default c("NZ", "AU")).
Tried in order; first valid match wins.
Value
A standardised E.164 phone string (e.g. "+64211234567"), or
NA_character_ if invalid.
Examples
standardize_phone("021 123 4567")
#> [1] "+64211234567"
standardize_phone("+64211234567")
#> [1] "+64211234567"
standardize_phone("0412345678")
#> [1] "+61412345678"
