How to Validate a Postal Code in Node.JS

When working with location information, ensuring your data is correct will save you from accidental shipping or billing mishaps and prevent future headaches for you and your clients. Postal codes provide exact information for any location internationally. Outfitting your systems with the ability to automatically validate any postal code with the following API to return location information will save you time and energy and help you better your business.

The first step in our process is to run this command to install the SDK:

npm install cloudmersive-validate-api-client --save

You can also add this snippet to your package.json:

"dependencies": {
"cloudmersive-validate-api-client": "^1.2.4"

Then, we will call our function, AddressValidatePostalCode:

var CloudmersiveValidateApiClient = require('cloudmersive-validate-api-client');
var defaultClient = CloudmersiveValidateApiClient.ApiClient.instance;
// Configure API key authorization: Apikey
var Apikey = defaultClient.authentications['Apikey'];
Apikey.apiKey = 'YOUR API KEY';
var apiInstance = new CloudmersiveValidateApiClient.AddressApi();var input = new CloudmersiveValidateApiClient.ValidatePostalCodeRequest(); // ValidatePostalCodeRequest | Input parse requestvar callback = function(error, data, response) {
if (error) {
} else {
console.log('API called successfully. Returned data: ' + data);
apiInstance.addressValidatePostalCode(input, callback);

Now, you can validate postal code information with ease! You can find your personal API Key on the Cloudmersive website, providing you with up to 800 call across our library of APIs.
