Keep Your Phone Numbers Well Formatted

A little snippet to normalize an input phone number into a consistent international format, without blank spaces and leading zeroes. Any number without leading + is assumed to be domestic.

Replace internationalCode in row 2 with the country code of your region (e.g. ‘+1’ for the US).

    private static String normalizePhone(String inputPhone){
        String internationalCode = '+356'; // Replace with your country code
        if(String.isNotBlank(inputPhone)){
            // Check if the original input starts with +
            Boolean startsWithPlus = inputPhone.startsWith('+');
            // Remove non-numeric input
            String notNumbers = '[^0-9]';  
            inputPhone = inputPhone.replaceAll(notNumbers, '');
            // Remove leading zeroes and plus
            inputPhone = inputPhone.replaceFirst('^0+', '');
            // Add International Code to numbers without originally leading +
            inputPhone = startsWithPlus ? ('+' + inputPhone) : (internationalCode + inputPhone);
        }
        return inputPhone;
    }
