Regional Business PIN Code List

I need a clean, up-to-date database of businesses located in a single region of my choosing. For each record I only care about the address component that pinpoints location—the ZIP / PIN code. No street names, cities, phone numbers, or opening hours are required.

Your task is to research and compile every unique PIN code that is actively used by businesses in that region and deliver it in a spreadsheet (Excel or Google Sheets is fine). Please make sure each entry is accurate, deduplicated, and sourced from reliable public listings. If you already have scraping scripts or access to commercial datasets, feel free to use them as long as the final list is verifiable.

Deliverable:
• A spreadsheet containing one column: “PIN / ZIP Code”, listing every valid code found for the specified region.

I’ll supply the region details and any boundary notes once we start.
