It's free because it should be
We've been there before: funds are limited and address verification seems like a burden more than a necessity, even though it may be vital to what you do. To make better address data accessible for everyone, we're providing some lookups for free to everyone... forever.
In return, spread the love
If you stay on our free plan, all we ask is that you tell other people and organizations. For example, tweet about us on Twitter; give answers on Stack Exchange or Quora; publish a press release or blog post; write a review about your experience; tell your friends, associates, and other departments/branches of your organization.
Please also mention your free use of our services on your website:

Your first month
New SmartyStreets customers get 250 US address lookups per month for free. This allows you to process your existing list of addresses or test our API as you integrate it with your system.
Free forever after that
While you're on the free plan, you can login and renew your account with 250 lookups every month. If you need more lookups, you can upgrade easily at any time.
