Does anyone have a source for cross-referencing 9-digit zip codes to their county? I’ve scoured the net pretty hard looking for one and even found a site that seemed to sell it cheap, but they’re apparently out of business. Sources appear to come from CDC (link is dead) and HUD (doesn’t have what it seems to promise . . . 5 digit zip codes only) and I can’t make them work.
This is for state government. We’re looking to place Zip+4 into the proper county for hundreds of thousands of records, need a data table as a source. Onesie lookups and Geocoding don’t look like viable options.
This is burning thousands and thousands of taxpayer dollars. If anyone can provide a lead I’d very much appreciate it.
