Complex address systems and its verification have continued to be a big riddle for technology companies. Currently address verification is done manually by matching the address mentioned in the identity document with the address filled in any kind of application form filled by the customer.
Companies grapple with a wide variety of fraudulent activities where some users rig addresses to avail discounts or commit a fraud, and manual checks involving human resource can be a huge operational cost and error prone for the companies. This has been a major pain point for e-commerce companies which bank on the last-mile logistics and ultimately bleed revenues. That is why address verification must be given impetus during the very initial step of identity verification process.
We have taken a novel approach to solve this issue by building a unique Address Net model to match the address in the identity documents with the address in an application form. We have used state of the art deep learning models to identify different components from the address strings automatically.
The unique features of the model are: –
Data pre-processing and the scoring Logic
Post component identification and data pre-processing, an overall address match score and a component wise match score is calculated for the two address strings.
The component wise match score gives the end user a flexibility to assign own custom rules on different components as per their use case and requirements, for example: an e-commerce company would like to give more weight to last mile address components like premise, sub-premise, house no. etc.
