Why our data is different:
We insist on quality! In the zip code
/ postal code arena, there is our premium data and there are U.S. Postal
Service generic copies.
verify our data! We have spent thousands of hours manually verifying
our zip codes and related data to ensure that it is the most accurate
data possible! Government data, which others sell, is often outdated,
inaccurate and not suited for many commercial applications. We standardize
the spelling of our place names. For instance, in the USPS file, they
will have ST THOMAS in one place and SAINT THOMAS
We only charge you for the data you
want! You can choose the base product and only the add-ons you want.
We have a custom data extraction tool that lets you extract only
what you want.
give you extra records with misspelled names in them! Our Pro-Zipcode
Deluxe product has alternate city names (because zip codes can cross
city boundaries). The generic copies have about 76,000 records with
alias records which normally are intentional misspellings
of valid city names. For instance, 17702, the USPS has some of the following
city names: S WILLAMSPOR, S WILLIAMSPRT, SWMSPRT for South
Williamsport. For 41465 (Salyersville, KY), they have 25 different entries!
This is not what you want for your zip code data!
We update our data about every 2 months.
Once a month is too often and quarterly isnt enough for most businesses.
We manually verify our zip codes, area codes (because of splits) and
other data every release as well.
We notify you when new versions are
available. We will e-mail you when a new version is available.
Established in 1992,
we started selling just a simple 5-digit zip code file over the Internet.
We were the first to sell zip code data on the web! We quickly received
requests for additional countries and add-on products. Soon, data products
and related tools and services became our only business.
Today, we have thousands of clients, from small
businesses to many of the Fortune 500 companies (including over
half of the Fortune 100!). They rely on our data. We strive
to ensure the best data possible!
