Using a master address list to improve asset tracking main image

Companies purchase national master address lists to use in many ways for many reasons.

Though some might assume the only reason to purchase a national address list is to blanket-mail or ship things to people not already in a company’s database, the lists are extensively used for asset location tracking, resource planning, market intelligence, operations optimization, business strategy, and decision-making.

Let’s take a closer look at the first non-mailing use case: asset location tracking.

Asset location tracking

Many companies have physical equipment located throughout their service regions. But tracking assets can get tricky when legitimate alias locations exist. For example, the following two addresses represent the same location or delivery point:

370 7TH AVE, NEW YORK, NY 10001
7 PENN PLZ, NEW YORK, NY 10001

An alias location as indicated by LACSLink

By separately entering both addresses in Smarty’s Single Address Verification tool, you’ll see that the second one is “Flagged for LACSLink” which indicates it’s an alias location.

Verified address and verified alias location

Might a company be confused and double-count their assets - once for each valid address? It happens.

SmartyKey Unique Address Identifier

The best master address lists help eliminate asset location and accounting confusion due to duplicate alias locations because they include a persistent unique identifier, like Smarty’s SmartyKey, which unifies all alias locations under a single, verified address having a single ID.

For example, the two addresses mentioned above share the same unique identifier, an integer of up to 10 digits. In fact, if the address had 20 aliases or more, all would share the same unique ID.

Because of the unique ID, deduplication, data blending, and accurate asset tracking have become a breeze for even the most massive databases.

Accessibility best practices at Smarty

An enterprise-level customer of Smarty’s recently shared how impressed they were with our accessibility-first approach, inquiring about how we designed our tools to function in a way that feels equitable and usable for everyone. At Smarty, one of our core values is outwardness — seeing people as people, not objects or caricatures. Every person who interacts with our tools has their own needs, wants, and objectives, and accessibility is one of the most meaningful ways we connect with people - an area we’re striving to improve.

Introducing Smarty’s mascot… Hermes?

Greek gods, as it turns out, have a lot to say to the mortals on Earth and the souls in Hades. What they don’t have is time to travel from Olympus all the way to Earth or Hades just to tell a mere mortal to perform 12 labors… or eat a magical herb… or free Odysseus. That’s why the gods have a personal messenger: Hermes. Equipped with winged sandals, Hermes travels between Olympus, Earth, and the underworld with lightning speed (Get it? Lightning? Because his dad is Zeus? 🤣)Smarty also knows a thing or two about outrageous speed, and that’s not where our similarities with Hermes end.
