Shopping around? Ask these

We would rather you checked. These are the questions that actually separate one ZIP+4 data provider from another — and our answers to them.

Is the data licensed, or scraped?
We are a non-exclusive licensee of the U.S. Postal Service. ZIP+4 is not a dataset anyone can legitimately assemble by crawling.
How much of the file actually carries coordinates?
The number most providers will not put in writing. Ours: ~60% on Standard, ~80% on Premium, ~95% on Deluxe — and we say what the coordinate points at, which is the other half of the question. See the edition comparison.
Can you apply a monthly change file, or must you reload everything?
Every record carries UpdateKey and Action, so you can apply adds and deletes rather than rebuilding 48.5 million rows each month.
How often is it updated, and for how long?
Monthly — 12 times a year, for the whole term you buy.
Can you see the price without talking to sales?
Yes. Every price is on the pricing section, starting at $399.95/year. No demo required, no quote to chase.
Does it renew without asking?
No. There is no automatic renewal — when the term is up, you decide.
Can you get history, not just today?
Yes — monthly ZIP+4 publications back to September 2007, as a one-time purchase. See the Historical ZIP+4 Database.
Are there query limits or per-call fees?
None. You download the files and query them as much as you like, on your own infrastructure.
What if it turns out not to fit?
30-day money-back guarantee, unconditional.
Who answers when you call?
A person, in the United States, on 1-800-425-1169 — during business hours, usually within the hour by email too.
