Hello and welcome to the Community @Shivam_Bhateja!
Are you working on the mobile or web app? If you are using mobile here is the support article for more on the barcode field type.
At the moment, we don’t natively support the ability to generate barcodes using Airtable. However, people have successfully built integrations to do this – some folks talk about how to do so in this community forum thread.
Let me know if I can help provide any more information, and if this helped answer your question please mark it as the solution :white_check_mark: .
