You can simply add validate class for validation in magento 1.

For Phone Number Validation

'validate-phoneStrict' => 'Please enter a valid phone number. For example [phone] or 123-456-7890.'
'validate-phoneLax' => 'Please enter a valid phone number. For example [phone] or 123-456-7890.'
'validate-fax' => 'Please enter a valid fax number. For example [phone] or 123-456-7890.'

For Zip Code Validation

'validate-zip' => 'Please enter a valid zip code. For example 90602 or 90602-1234.'

You can use the below extension, it automatically adds validation based on the selected country with the country flags and automatically sets the user country by default based on their Geo IP location.
