PAN Card Validation in SQL | Real World Data Cleaning & Validation Project

Learn how to clean and validate Indian PAN card numbers using SQL – just like in real data engineering projects!

This video walks through a complete, real-world assignment that one of our subscribers received while on the bench. We use PostgreSQL to clean, validate, and categorize PAN numbers with rules like:

- Format checking with regex

- Removing duplicates

- Handling missing values

- Checking for adjacent repetition and sequences

📊 You’ll also see how to create a summary report and write modular, production-ready SQL code.
