The USPS Street Address Standardization Library allows you to standardize street addresses according to USPS guidelines from USPS Publication 28. This is useful for bulk mail compliance, and to match street addresses from different systems. It standardizes street numbers, pre-directionals, post-directionals, directionals within street names, rural routes, street abbreviations, and unit abbreviations.

Unlike other address standardization software, there is no monthly subscription, and there is no maximum limit to the number of addresses that can be standardized. It performs the standardization completely offline. It is a perpetual license.

StandardizationLogic standardization = new StandardizationLogic (); // trial mode 

// StandardizationLogic standardization2 = new StandardizationLogic ( "place user name here" , "place license key here" ); // license mode 

string addressToStandardize = "1500 Serpentine Road, Suite 100" ;

string result = standardization.StandardizeStreetAddress(addressToStandardize);

//This will output: 1500 SERPENTINE RD STE 100

Console .WriteLine(result);
