The key difference between GreatData.com and its competitors is its attention to detail and the fact that their products have been continuously refined since the 1990s. "Just using government data isn't sufficient."
Duggan continues, "One of our frustrations has been that people think that all ZIP Code databases are alike. We had one client who was using our ZIP Code data in an application sold to Apple. He switched to a competitor and told me, ‘Data is data, right?’ I could tell that he really wasn’t looking for an answer, but wanted to justify his decision to buy cheap, so I let it go. A few years later, Apple let him know that they weren't pleased with the other company’s data, so he switched back to us."
"With each version of the data, we go through hundreds of steps to ensure accuracy." reports Duggan. "We don't know of anyone else paying this high level of attention to detail, and our clients appreciate it!"
"A large auto manufacturer recently told us, 'Over the last 8+ years of working with your company, we’ve enjoy a great relationship and very accurate data. It’s been a pleasure working with you.'"
Recently GreatData decided to check out a main competitor’s latitude / longitude coordinates. This is the key ZIP Code data element that most of GreatData's clients want and an area that GreatData has spent countless hours on to get it right, even in remote areas such as Alaska. Their competitor provided a small sample file on their site, so GreatData mapped the coordinates and was shocked to find out the following:
• 56% of the latitude / longitude coordinates were over 3 miles off.
• Almost 10% were over 15 miles off.
• About 4% were over 20 miles off!
This was not in a rural area, but in a major metropolitan area. When companies use that data in their store locators, it can cause them to lose business.
