Hello Dan

that answer in FAQ is good enough for me! and since users of my app only use it at data entry, to get suggestions, no mass/batch processing would occur - just as USPS likes it. and the results (even if not the best matching/verification/correction) is at this time more then good enough for me.

>Sort of. The database is up-to-date and free, but they do a poor job of attempting to correct addresses that might not be entered correctly. Where a 3rd party product would correct an address, USPS will return an error. But good enough for most situations.

>>do you remember where you saw the mentioning of that the USPS site is "...but are willing to let people do it"? it would be helpfull to have a reference for the future just in case they complain at a later point in time.

>The purpose of the ZIP+4 look-up system on our WWW server is to avail the public of a simple means of obtaining ZIP+4 Code information. The primary audience we seek to serve are customers who occasionally require ZIP+4 Codes.

>ZIP+4 Lookup is intended for interactive use, not automated script processing. Although we do not intend to impose a limit on the number of inquiries we allow a customer to request in a given session. If we determine that our open-access policy is being abused or overburdened, we will have to review it. Regardless, we do not intend to offer batch processing capabilities via this service.

>Sounds like Don't-ask-don't-tell to me. It's useless for large batches anyway, so my type of use is certainly not going to burden their server.
