When will new zip code data be made available?


Zip codes are not census geography so they are always one of the last products that the Census Bureau produces. Another reason for the delay is that zip codes are built from underlying census geographies like census blocks and tracts. New census tract boundaries will not be available until 2011.

Census tract data will be available in late 2010 - ACS 2005-2009, which will be based on Census 2000 boundaries. The following year, the census tract file (ACS 2006-2010) will be based on definitions based on the 2010 Census.

Zip code characteristics will be available in the 2007-2011 5-year estimates for zip codes. You can access them thorough American Factfinder.
