Nope. We don't think so. But judge for yourself. For single address verification, you just input or paste the address into Smarty's free address validation tool. For instructions, see the 2-minute video demo on How to Validate a Single Address.

For bulk address validation, choose from 5 easy ways to do it without knowing a lick of coding: 1) file upload into a web interface, 2) Microsoft Excel add-in, 3) Google Sheets add-on, 4) QGIS mapping plugin, 5) Command Line Interface (CLI)

For address correction API integration, we've prepared world-class, clear, easy API and SDK documentation that your developers will love. You'll be up and running in no time and we're here for you by phone, chat, or email with super responsiveness if you have questions or need help.

Address verification helps you delight customers, reduce fraud and business risk, minimize shipping returns and charge-backs, cut postage and delivery costs, enhance and deduplicate records, merge databases, improve data governance, and more.

Think of the savings and improved collections by just improving your billing addresses. What could delivery point verification and improved delivery logistics and rate do for customers' delivery experience and your bottom line? In some cases, the time saved or cost-saving delivery rates and postage discounts alone can entirely pay for the address verification service.

"...our shipping costs savings ends up paying for the cost."

User in package delivery, G2 review

"We saw our undeliverable shipping rate fall from 5% to <1%, which represents a ton of savings for us."

Address verification improves operations, cuts costs, increases revenue and improves your bottom line. It may be one of the fastest, easiest, highest ROI things you can do. Oh, snap!

Abso-friggin-lutely! You can use Address APIs to verify addresses and reduce checkout errors, such as spelling errors, as people complete your web forms. When the user enters their entire address, the API can suggest the correct, normalized, standardized address within milliseconds. See an e-commerce checkout UI case study. To additionally improve the customer experience, consider adding Address Autocomplete, which predicts correct, verified addresses as the user types.

When using International Address Verification, the API applies the address formats according to the respective country standards.

Address validation helps keep your data clean at the point of entry and get your mail, packages, and people to the right place. Use address verification to delight customers while reducing wasted postage, return, and chargeback costs.

Google does a lot of things well—Gmail, Google Assistant, and selling user data; and other things not so well—Google Glass, Google Latitude, and Google+. Only time will tell how Google's Address Validation will turn out. Address Validation is what Smarty has specialized in for more than a decade. Our very lifeforce is poured into giving our users the very best experience today and in the future.

We invite all who may be on Google address validation to graduate to Smarty's professional-grade, high-volume service.

"BEST service available. Address Verification that just Works - the way its supposed to! We recently reviewed service providers for address verification - checked out Google's offering and USPS but when looking at uptime and speed of returning info - Smarty couldn't be beat. Our e-commerce solutions wouldn't work without the reliable info Smarty provides for us. Reasonable pricing too!"

Rhonda R, VP

Smarty is differentiated as a quality, enterprise-grade provider relied on by thousands of companies including industry leaders like Microsoft, FedEx, and NASA. Here are a few ways Smarty is clearly a smarter address validation choice than Google:

• Price: Smarty's US Address Verification pricing is significantly better than Google's

• Accuracy: Accuracy matters a lot. Smarty offers building-level and apartment-level accuracy in milliseconds. Smarty constantly improves its data based on what we learn from processing billions of addresses each day. See the 2-minute video, Graduate from Google: Validate Addresses More Accurately.

  "The accuracy and speed are fantastic!"

  James C, VP

• Speed: Google maxes out at 100 address lookups per second. By contrast, Smarty's standard plans start at 50 addresses/second and our enterprise plans start at 300/second. Our speeds go up from there.

  In Smarty testing, Smarty is more than twice as fast as Google for international address validation. For US validation, it's like comparing the speed of walking to flying where Smarty is typically 200 times faster than Google.

  When a government agency needed to validate 75,000+ addresses per second in the cloud, they turned to Smarty. And we delivered. That's 750 times faster than Google. Need faster? We can do whatever you need. Really.

  "[Smarty's] response times are lightning fast."

  Tim R, Senior Software Developer

• Ease: Smarty is super easy to get started with quickly. You can start validating addresses in bulk simply by uploading a spreadsheet of addresses, no programming required. With Google, bulk validation requires programming work.

  A product feature example of Smarty ease is that Google requires a 2-character country code, whereas Smarty can support the country spelled out, as well as the 2 or 3-character country code.

  Also, all of Smarty's APIs are supported by worldclass API and SDK documentation that makes integration and startup a snap. Your developers will love you for choosing Smarty.

  "One of the best features is that our developers quickly and seamlessly integrated the API call. It's one of those products that sits in the background and just delivers over and over again. Very easy to use and very accurate. It's a fantastic alternative to something like Google places. We've been a customer for 10+ years and the team at Smarty is always responsive and easy to work with."

  Mark D, Director, IT Customer Service

• SmartyKey®: Every address validation result returns a persistent, unique SmartyKey identifier that never changes despite changes to an address. It’s an easy way to identify and merge or purge all those duplicates in your database and turn your address chaos into pristine location data.

• Autocomplete Validation: Smarty verifies/validates autocompleted addresses. Google does not. And, in our estimation, the performance of Smarty's Address Autocomplete is far superior to Google's.

• Data Expiration: Smarty's data doesn't expire. Google's data expires after 30 days. That means Google customers could end up paying over and over to validate the same address data. Google's address metadata also expires after 30 days. Smarty's does not.

• Mapping Flexibility: Google forces you to use its mapping tool. From google's documentation, "It is prohibited to use Address Validation API data on a map that's not a Google map." If you want to plot addresses via maps, you're limited to using Google Maps per their terms. That means you can't use ArcGIS, QGIS, MapInfo, or any of the many other powerful mapping platforms. With Smarty, you can use Google maps and any other mapping platform with any data overlays for superior visualizations, analysis, and decision-making.

• Bulk Processing: With Smarty, bulk address processing is as easy as uploading a list of addresses. Google's bulk processing requires custom code work.

• High Volume Testing: Smarty provides a 42-day trial period that supports high-volume testing. Google does not.

• Support: Smarty's support is legendary. Google's isn't.

  "Simply the best! I cannot speak highly enough of [Smarty's] customer service. Everyone there is friendly, professional, knowledgeable, and very quick to respond to questions, concerns, and they are eager to assist with configuring and integrating [Smarty] into your system."

  Tim R, Sr Software Developer

• Focus: Smarty is 100% focused on the address; we have been for more than a decade and will continue to be. Google, on the other hand, has hundreds of products they've launched and then sent to their failed product graveyard. See killedbygoogle.com for a full list. Will address validation also be scrapped in the future? With ongoing research and development, you can count on Smarty to guide you into the future with the leading address verification/validation service.

  "[Smarty is] always improving their service and their customer service is outstanding."

  Joseph M, Web Developer

• Terms: Google's terms and conditions are notorious for being confusing and constantly revised. Ours are straightforward and easy to understand.

  "We've been a customer for 10+ years and the team at Smarty is always responsive and easy to work with."

  Mark D, IT Director

• Privacy: Unlike Smarty, Google is all about building profiles and advertising to people and companies based on those profiles. Do you trust your client data with Google? Is that sort of data privacy a concern for your organization?

• Value: Combine Smarty pricing, performance, features, and support, and Smarty is your clear value leader versus not only Google but also other address validation providers. Compare for yourself. Offering you industry-leading value is our thing.

US address validation APIs normalize addresses to match the standards of the USPS. Smarty also offers International Address Verification. Address validation APIs efficiently integrate with websites, databases, CRMs, and other software to enhance address data quality.

Smarty builds on the data the USPS provides and gives ridiculously fast address validation, address data enrichment, standardization, and autocomplete with our own collection of flexible address APIs. Do an online 42-day free trial of the US Street Address API Tool.

Yep. As long as you can make an HTTP request and parse a JSON response, our APIs can be implemented in almost any CRM. Learn more about Smarty API capabilities.

"Smarty's API has been straightforward to integrate into our CRM and our business intelligence tools. …[Smarty] is a fantastic product.

Shawn R, IT and Security Manager

US Core Address API: 99.98% of requests containing a single lookup will respond within 500ms (over a five-minute period). See the full SLA.

"It ALWAYS works. We've been using their API for 3.5 years and have never once had an outage."

Smarty offers up to 55 points of data with each address when it validates an address. Those include longitude, latitude, Residential Delivery Indicator (RDI), vacancy, county name, congressional district, and more. See the full list above and/or watch the 2-minute video, What Data Do You Get When You Validate an Address.

Please be aware that based on the availability of data, it would be unusual for an address to contain all 55 points of data. However, most addresses come with most data points. Want to see for yourself? Try address validation free for 42 days.. Also, note that the longitude and latitude coordinates included with address verification are street-centroid. If you need the highest level of accuracy, see our Rooftop Geocoding offering.

Every address validation result also returns a persistent, unique SmartyKey® identifier that never changes despite changes to an address. It’s an easy way to identify and merge or purge all those duplicates in your database and turn your address chaos into pristine location data.

Check out how easy it is to clean and deduplicate records based on address in the 4-minute video, How to Remove Duplicate Addresses in Excel.

Also, we have a bulk address verification tool that works great for bulk lists. See some tips on Preparing Your Mailing List for Address Validation.

There are a few ways to renew. You can renew with an on-file credit card (self-service) or through your account manager via invoice.

In the self-service, credit card option, you can choose to make renewal automatic so that you never have to worry about service shutting off due to exceeding your plan's allocated number of lookups. We send an email when you have used 90% of your plan's lookups, to alert you that an automated billing charge is coming up. Following the charge, we send you a receipt.

If you select an annual plan with invoicing, your account rep will remind you of the upcoming renewal. And you can also set up autorenewal for peace of mind.

Smarty has been 100% laser-focused on location data intelligence for more than a decade, and that focus commitment is something you can count on in the future.

"I've been using Smarty for 10+ years to verify addresses…I highly recommend [Smarty] if you have a need for address verification."
