The National Information Data Center (NIDC) has published the National ZIP Code® Directory for over 30 years. Now, it’s the only hard-copy ZIP Code® directory available. Using data licensed directly from the USPS, our two-volume set features the most complete, up-to-date ZIP information available. You can look up U.S. streets in large cities and post offices by ZIP Code®, 3-Digit service area, and even national area code listings.

The 2-volume 2011 ZIP Code® Directory set includes:

• More than 21,000 updated ZIP Codes®, covering 151 million addresses, licensed directly from the United States Postal Service.


• Easy-to-reference ZIP Code® look-up. You can search by city, state and street to avoid additional
  mail and overnight charges.


• Completely updated U.S. telephone listing. You will save time and money on directory assistance fees with this easy-to-use guide.

Now includes newly updated, easy-to- read individual 3-Digit U.S State Maps. The 8.5" x 11" map located after the each state information page shows every 3-digit ZIP Code® in the area.

Now Available! Official U.S. Census Bureau State and County Demographic and Economic Profiles. Now you can get quick, easy access to facts about people, business and geography for the states that you do business in and how it compares to the overall U.S. population.
