Come check out our newest webinar, where our specialists talk about how to analyze Smarty's API output like a Pro! Check it out now!

Smarty's US Street Address API and International Street Address API provide a lot of output. Things like Carrier Route, Congressional District, geocode, eLOT sequence, timezone, and much much more are available with every address check.

But there may be points of data that you are not entirely sure what it means, or how to use it.

In a recent webinar, we brought Lyle Durland, Head of Support, and Jeffrey Duncan, Technical Product Manager, together to outline some of the more useful points of data, and how to interpret it. Watch it now.

US Street API slide 1

Lyle began by pointing out that there are two particular properties that are extremely valuable: DPV Match Code, and Enhanced Match. These data points will answer:

  • Which addresses are valid?
  • Does an address actually exists or not?
  • Which mail carriers and delivery services will be able to deliver a letter or package to the address?
  • Is the address in the output is the same one in the input?

First, here are the possible values for DPV Match Code.

DPV Match Code values

So this tells you if an address is present in the USPS data and can be delivered by them. It can be handy to know if you're mailing something to discover that you're missing an apparent number.

There are some carriers that will ship to addresses that are not in the USPS address database but still exist.

This is where Enhanced Match data can come in very handy.

Enhanced Match values

If an address is marked as non-postal-match in the enhanced match data then you can likely still mail it.

Interpersonal skills and how they tie to leadership, teamwork, and business growth is no cakewalk. Yet every business knows that retention of employees is largely contingent upon quality interpersonal skills. That's why so many organizations implement principles and techniques taught by the greats. I'm sure you've heard of Dale Carnegie's "How to Win Friends & Influence People", Steven R. Covey's "The 7 Habits of Highly Effective People", or maybe even "Dare to Lead" by Dr. Brene Brown.

Properly implemented address autocomplete can help businesses to improve conversion rates by speeding up address entry, improve address data quality by reducing typos, and reduce user frustration related to errant address data.  But, if you choose the wrong autocomplete API or make implementation errors, those benefits can evaporate. In our new ebook, "Magical Benefits of Address Autocomplete," where we've compiled valuable insights and implementation tips, including the best practices we'll cover here.

It's often said you need two skills to find love: sales and marketing.  You need marketing skills to present yourself well and gain the attention of the person you want. Then, you need sales skills to lie like you're the devil himself.  But what if you aren't conventionally attractive and (like the sales team at Smarty) aren't willing to lie? To compensate, you'll need to dial up your marketing; we're talkin' data automation, streamlined & integrated data systems, time-saving and cost management, eliminating human error, and workflows like crazy.
