Director of Product Management

SmartyStreets delivers exactly what we need — reliable, fast, and accurate address verification. Since implementing their US address validation, we’ve drastically reduced the amount of returned mail we receive.

E-commerce consultant

The product is very robust, from a user and a developer perspective. When I’ve had questions about address records, customer service was able to provide very good insight. And the database seems very nearly complete, for the US anyway.

IT Lead - Patient Systems

It's fast in response even though we implemented it using a proxy on our app server and not hitting the APIs directly, it's still fast.

Additionally, its comprehensive and user-friendly API documentation greatly facilitates our developers with integrating address validation into our various use cases. Whenever we've needed assistance from customer support, they've consistently provided prompt and knowledgeable responses, backed by thorough documentation.

Senior Software Engineer

The address validation services are critical for our business and saves staff time from having to manually process address validations/corrections with other software solutions.

Wedding Invitation Designer

It is the right address data service for wedding professionals, and I believe continued feedback from users like me will make it even better.

Product Manager

The capability to efficiently breaks down complex address strings into individual components such as street name, city, state, and zip code.

As a wedding stationery designer, I love how accurately Smarty validates both domestic and international guest addresses.

General Manager

Meaning, If I paid for 5K searches last month but only used 4K, I should be able to carry over those 1K to the subsequent month...at least for 2-3 months before they expire.

Fast, accurate address lookup integrated with our product, without introducing a "new and different" UI look and feel.

Head of Operations

Initially, I was moving too fast and selected "Address Verification" subscription rather than the "Address Auto-Fill" subscription that I needed.   But switching subscriptions was no problem.

Happiness Engineer

This made it slightly harder for me to navigate the site and get my simple task done.

Managing Director

It saves us time, reduces errors, and keeps everything running smoothly — exactly what we needed.

Head of Product and Data

The accuracy is phenomenal - it's saved us from countless shipping errors and returned mail.

Our use case is related to new residential construction, and they seem to be getting newly registered addresses with minimal delay.

SVP, Product and Engineering

This is limiting for us since we deal with land parcels that are not developed and our customers cannot find the addresses.

I receive accurate results for the addresses and longitude/latitude coordinates within seconds which is very useful.

Principal Solutions Architect

We are able to validate postal addresses in seconds using their API, and couldn’t be happier.

The ability to validate US addresses is also great, the tool ensures only accurate and deliverable addresses are accepted.

Sr. Data Migration Analyst

I tested two other address validation platforms prior to making the decision to go with Smarty exclusively for my address transformation needs.

VP of Technology

I loved how easy and fast Smarty made it to validate and autocomplete addresses—super helpful for improving data accuracy without adding extra work.

Principal Engineer

The solution boasts exceptional uptime with minimal service disruptions, ensuring consistent data integrity and processing.

We deal with all property types and I have not found anyone (including Google) that supports condos as well as Smarty.

Owner, Member, Secretary, Treasurer, Engineer

We run marketing campaigns twice a year and the monthly billing works very well for our needs.

Software Engineer

The documentation made it super simple to get going and build a solid solution.

Solution Architect

The reliability of their address validation coupled with the peace of mind their customer support provides has made Smarty an invaluable partner to our business.

Director of ecommerce

If the user is utilizing a virtual private network (VPN), the Smarty response may be 400.

The tool is simple, intuitive, and integrates easily into our workflow.

Architect

Its service accuracy and speed are unmatched, streamlining the user experience significantly by reducing errors and improving efficiency.

The outcomes are satisfactory, enabling the development of an intuitive address validation system.

Salesforce Administrator

Smarty's auto-complete and auto-correct functionalities are probably the features I like the most. But it doesn't stop there.

Office Manager

Canada being in a separate search, it makes sense, but I wasted some of my searches because I didn't realize they were mixed in.

This includes the autocomplete and the verification services.

After trying multiple address auto-complete solutions on the market, Smarty was without hesitation the cleanest and most robust one.

Director of Operations

There is also the 1 in 100,000 addresses that while USPS valid, just do not validate well through the API call.

On an occasion where we encountered a billing issue, their team's swift and effective resolution ensured that our mission-critical app remained uninterrupted.

The fact that it is fast and accurate, when met with a 4400-line spreadsheet in a new team I needed help, this was it!

Their service is not just a tool but a vital component of our infrastructure, ensuring data integrity and operational efficiency.

Auto-complete of addresses is only for places where USPS et al.

JavaScript is not my strength, so keep that in mind. But better or maybe just more examples of how to integrate it would have been helpful.

From creating an account to using it on our application, it's seamless, without flaw.  

It was the most cost effective and low impact solution for us to automate and integrate address correction.

In the realm of custom software development, integrating reliable address verification can be pivotal.

Very smooth from trial to integration with production, very responsive support and handles scale well.

Engineering Manager

The ability to identify addresses is getting better and better

The pricing is fair but the only drawback is the inability to carry-over searches.

Senior Engineering Manager

The documentation is super easy to follow, and the integration was easy for us

The API integration is seamless, fitting effortlessly into our bespoke platform with minimal configuration.
