How our Database Subscriptions Work

Becoming a subscriber to any of our database products is easy and your satisfaction is guaranteed. When you purchase an annual subscription, you may immediately begin to download and use the data. You can download as often as you like for the duration of your subscription. Our ZIP Code and Postal Code databases change regularly so it’s a good idea to get a fresh copy every month or so. Our specialty / targeted-use data changes less frequently but improvements and updates do occur throughout the year. In fact, with recent advances in mapping technologies, some of these products have never been as accurate as they’ve become in the past months. When your subscription is nearing an end, we will notify you within a couple weeks of the expiration. If you wish to continue your subscription, you can choose to renew without interruption. Otherwise you can simply let it expire. The bulk of our clients elect to have their subscription auto-renew upon expiration. This is safe because we always notify you prior to renewing anything and give you plenty of time to determine your preference. More importantly, we are committed to insuring your satisfaction and are determined that you will not have any misgivings about doing business with GreatData.com. If you have any questions, feel free to contact us. Our support desk has real people and is located at our headquarters here in the United States.

GreatData.com - Enterprise Level Databases that are Clean, Precise, and Current

For over 20 years GreatData has matured our processes to provide the finest enterprise level databases on the market.

Compared to the many low-end, repackaged government database products on the market today, we use the best sources to obtain the most current and accurate data possible. ZIP Code databases sourced from the Census Bureau or US Postal Service may have thousands of duplicates, different spellings for the same place, and numerous out-of-date records. Our zip code database is very clean and appropriately lean. We utilize a sophisticated cleaning and standardization process that is unmatched in the industry. Our excellence is a result of years of experience and a desire to deliver precision products based on very high standards. We believe most of our customers will yield a greater return on their investment by choosing a superior data product. Good data can save thousands... bad data is costly.

We not only guarantee a clean, accurate, and up-to-date database product, we believe it to be the finest in the industry.

Sincerely, GreatData.com
