The free web tool above limits you to 10 address checks per batch. With a paid subscription, you can process larger address files containing thousands of records. We recommend you use the above tool up to 25,000 addresses at once. For more than 25,000 addresses, we recommend you use the Command Line Interface (CLI) to do your bulk address list validation. You can verify huge batches of hundreds of thousands of addresses at once - the only limit on the amount you process through the CLI is your subscription limit.
