> The data used to be available on CDROM (back in the 90s) but moved to an API in the early 2000s. Until August 2026, you used to be able to look up addresses for free.

What was the reason for the 2026 change to make it non-free? Some "government should be run like a business" (and therefore charge for services) BS, or was there some kind of abuse or privacy issues they were trying to limit?

My university used to get copies of the CDs in the 1990s. I think they came out quarterly. You had to pay for the CDs, but the data was free. We bought one copy and put it on a server for everyone to use.

All governments provide some services for "free" and charge for others. Sometimes it makes sense, other times it really is BS.

Mostly as a commercial shift under the new board of governors that are concerned on financials (except when it comes to throwing away new efficient mail sorting machines ahead of an election).

They spun it as supporting the new RestAPI based system they put in place, it does have more efficient rate limiting, and some controls like Mailer ID verification (able to tie who makes a request for a label to that actual label, etc.) that are supposed to help with fraud.
