What does the lookup return?

City, state, latitude, longitude, and timezone for every unique code. Each answer is a column in the results file.

A ZIP+4 resolves at its 5-digit code, and both forms of the same ZIP bill once.

Does it work outside the US?

Yes. Nine countries, each from its official national source, including UK postcodes and Japanese postal codes. The drop asks for the country when the file does not carry one.

Do you charge for duplicates?

No. The bill counts unique, valid-shaped codes. Duplicates and malformed rows are free.

What files can I drop?

Excel, Numbers, CSV, TSV, or a plain text list. A Google Sheets export works too. Spreadsheets convert in the browser when you drop them.

Free sample: A slice of your file is verified on the quote. Floor of 3, 5 percent of billable rows, cap of 10. A one-row file is the exception.
Unknowns refunded: If we cannot answer, that share comes back. If the job stops short, the remainder comes back too.
Results last 30 days: We email the download when the run finishes. Download available for 30 days.
Bring your team: On a plan, invite teammates from dashboard settings. Anyone on the team can drop a file and run it from the shared allowance. Owners and admins manage the plan and spending limits.
