FAQ

How can I validate a list of addresses?

To validate an entire list of addresses, follow the instructions in the free validation tool above. Note that this web tool defaults to trial mode, where you can only validate 10 addresses simultaneously. Get a free or paid account to process more addresses at once.

Alternatively, with a paid subscription, you can process your entire list with the Command Line Interface (CLI) tool.

We recommend the above web interface tool for smaller projects and the CLI for larger ones.

A paid subscription also unlocks Smarty's Google Sheets and Excel plugins that allow you to batch verify addresses right inside your spreadsheet programs.

Is it free to use the above bulk address validation tool?

Yes. You can verify up to 10 addresses at a time for free without an account in the above batch address verification tool.

Need more free lookups? Verify up to 1,000 US or 100 international addresses with a free trial.

How do batch address verification services work?

Batch address verification services follow these steps:

Begin by normalizing and parsing the input data into its respective address components.
Then, the entire address is standardized and formatted according to the official postal address standards of the destination country or territory.
Next, the validation phase is initiated, where the standardized data is verified against Smarty's entire database to determine its accuracy and legitimacy. Users can turn on Enhanced Matching to help find and match even some incomplete addresses.
Finally, Smarty’s lookup-by-address process returns the standardized, correct addresses as well as the original input addresses.

How many addresses can I validate with your bulk address verification tool at a time?

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.
