HOW IT WORKS
- Junk is free
- Duplicates and rows that are not a ZIP code never enter the bill.
- Exact price up front
- Choose the checks you need and review the total before you pay.
- Pay for the file
- One payment runs one file. Nothing to sign up for, nothing to top up.
- Unknowns refunded
- If we cannot answer, that share comes back. If the job stops short, the remainder comes back too.
- Private results
- The file runs your job and nothing else. Results are private to your download link and available for 30 days from upload.
- 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.

QUESTIONS
- What does the lookup return?
- City, state, latitude, longitude, and timezone for every unique code. Each answer is a column in the results file.
- What about ZIP+4?
- 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. 48 countries and territories from official national sources, including UK postcodes, Japanese postal codes, and Dutch 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. Spreadsheets convert in the browser when you drop them.
