How much does it cost?

The Actor is billed by Apify according to the pricing shown on the Pricing tab of this page. Runs are small and fast, and the Apify Free plan includes monthly platform credits so you can try it at no cost. You can set a maximum cost per run, and the Actor stops cleanly when that limit is reached.

Notes and limitations

• Data comes from the US Census Bureau Geocoder (TIGER address ranges, US federal work, public domain). Uses the current benchmark and vintage.
• Write each address on one line with city, state and ZIP, e.g. '1600 Pennsylvania Ave NW, Washington, DC 20500'. Addresses that cannot be matched return a row with a note.
• Coordinates are interpolated along the street segment, so they are approximate rather than rooftop-accurate.

Tips

• Start with a small test run, then scale up the input.
• Use Schedules to automate recurring runs and Webhooks or Integrations to deliver the data where you need it.
• Call the Actor from your code with the Apify API or the official JavaScript and Python clients.

FAQ

Does it work outside the US?

No. It covers the 50 states, DC and Puerto Rico.

What is a GEOID?

The Census Bureau's numeric code for a geography: state (2 digits), county (5), tract (11), block group (12) and block (15). Use it to join Census statistics.
