This article describes how to build an OCR API that extracts data from SS4 using our deep learning engine. If you want to automate your workflow, this article is for you. 




  1. You’ll need a free account. Sign up and confirm your email to login.
  2. You’ll need at least 20 SS4 images or pdfs to train your OCR.



Define your SS4 use case


First, we’re going to define what fields we want to extract from your SS4. 





  • Entity Name: The legal name of the entity. 


  • Address: The entity's full address (mailing, city, state)


  • SSN: The Social Security Number of the principal officer. 


  • Type of entity: The type of entity. 


  • Reason for applying: The reason why you apply for an employer identification number.



That’s it for our use case. Feel free to add any other relevant data to fit your requirements. 



Deploy your API


Once you have defined the list of fields you want to extract from your SS4, head over to the platform and press the ‘Create a new API’ button.


You land now on the setup page. Here is the image you can use for setting up the API, and my set up looks like this:



Set up your  SS4 OCR API


Once you’re ready, click on the “next” button. We are going to specify the data types for each of the fields we want our API to extract.

To go further, you can download this json config to set up your data model or do it manually.


Entity Name: type String that never contains numeric characters.

Once you’re done setting up your data model, press the Start training your model button at the bottom of the screen.

Deep learning SS4 OCR API



You’re all set! 


Now is the time to train your SS4 deep learning model in the Training section of our API. 


In a few hours (minutes if you're fast), you’ll get your first model trained and will be able to use your custom OCR API for parsing SS4 in your application.


To get more information about the training phase, please refer to the Getting Started tutorial. If you have any questions regarding your use case, feel free to reach out using our chat!
