I moved, so now I have to go through all my key accounts (banks, credit cards, student loans, etc.) to update my address. Why?
If Mint can get all my financial data in one place, why can't I update my address from one tool? I checked Yodlee, but they seem to only provide APIs for transactional data, not account address.
Am I missing something?
When you fill out a change of address card, it goes into the National Change of Address (NCOA) database. Many companies, from "junk mail" all the way up to your mortgage company, subscribe to services that routinely update their databases with NCOA data.
It can take two to six months for the NCOA stuff to filter all the way through the system, though, so even if you do fill out a change of address card, be sure to contact any company or organization whose correspondence you must get in a timely manner (e.g. mortgage, rent, bills, etc).
Still, for the truly lazy who don't mind a late fee or two, they will find you (for the most part).
