Middleburg, VA (March 5, 2019) - How do DMA ZIP codes provided by Nielsen compare to TRUCKADS ZIP codes? It's a question we are asked almost everyday. Our answer is; they are very similar. TRUCKADS ZIP codes may vary depending on when we update our market ZIP codes vs. Nielsen's DMA ZIP codes. This and other factors determine how similar our ZIP code list is within a given market. Do the differences matter? In our opinion, no. No ZIP code list is perfect except the USPS list maintained by the United States Post Office (www.USPS.com). The ZIP code list we source is updated once per year and ZIP code changes that occur across the country are relatively minimal. Published estimates indicate ZIP code changes don't amount to even 0.1% per media market, per year.

According to https://wikipedia.org, there were over 42,000 ZIP Codes in the United States in 2015. ZIP Codes are used for tracking U.S. mail and gathering geographical statistics in the United States. Because ZIP Codes are the cornerstone of the U.S. Postal Service (USPS) mail distribution system, USPS has long resisted changing them for any reason other than to improve the efficiency of delivery.
