Accessing ACF author field in a function

I have a custom field ‘zipcode’ and this is setup as a custom Author field. I’m using Relevanssi to do a standard search with the Authors as opposed to blog posts or pages. On the results page, I’m able to, in the loop, retrieve the custom zipcode field as such:

$zipCode = get_field('nestwell_user_b_zipcode', 'user_'.$userID );

and then I’m free to use the $zipCode variable to pull in each users zip code. However… I have a function in functions.php that needs to access this zipcode. For the life of me i can’t seem to figure it out. I need to construct a custom URL with the users zipcode from ACF in this function. Right now the $to variable is hard coded to a zipcode and it all works great. Though I need it to be dynamic for each user in the loop.

How can I achieve this??

function google_distance_between_places( $from, $to ,$decimals = 0 ){
  $url = (isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] === 'on' ? "https" : "http") . "://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";
  parse_str(parse_url($url)['query'], $zipURL);

  $from   = $zipURL['zip'];
  $to     = '99141';
  $data   = file_get_contents("https://maps.googleapis.com/maps/api/distancematrix/json?units=imperial&origins=$from&destinations=$to&key=xxx&language=en-EN&sensor=false");
  $data   = json_decode($data);
  $distance   = 0;
  if( !empty( $data->rows[0]->elements ) ){
      foreach($data->rows[0]->elements as $road) {
          if( $road->status == 'OK' ){
              if( isset( $road->distance->value ) ){
                  $distance += $road->distance->value;
              }
              $convert_miles = 1609.344;
              $distance = ( $distance / $convert_miles );
              $distance = round( $distance,$decimals );
          }else{
              $distance = "not_found";
          }
      }
  }
  return $distance;
}
