What are potential challenges with processing postal codes and street names in a PHP-based web application, especially in cases of multiple locations sharing the same postal code?

When processing postal codes and street names in a PHP-based web application, a potential challenge arises when multiple locations share the same postal code. To address this issue, you can utilize a combination of the postal code and street name to uniquely identify each location. 

// Example code snippet to uniquely identify locations with the same postal code
$postal_code = $_POST['postal_code'];
$street_name = $_POST['street_name'];

$location_identifier = $postal_code . '_' . $street_name;

// Use $location_identifier to uniquely identify each location
