getCountryCode() and getRegionCode() are mixed up

[StijnCoolen]

According to docs:

{{ entry.phone.getCountryCode() }} - The alphabetical country code
{{ entry.phone.getRegionCode() }} - The numerical region code

Actual (php code):

->getRegionCode() returns the alphabetical country code (ES when using Spanish phone nr.) ->getCountryCode() returns the numerical region code (34 when using Spanish phone nr.)

This also matches the libphonenumber-for-php docs
