Temporary postal mail forewards.

USPS NCOA (Change of Address) file is another major data source.

What makes me crazy about having your mail forwarded is that they often don't even forward it to your new address. I know because I once lived with a crazy person and had to move out and they just kept delivering all my mail there despite duly submitting my forwarding address and stressing the importance of it.

I still get mail for the last folks who lived here and they moved out 13 years ago.

But anybody willing to pay the post office for the data can find out your new address.

And then there's how we pay higher rates for first class mail so that junk mail can be cheaper.

It's almost like the government doesn't work for the people.

Thanks for the tip, from the link:

"There is, however, a loophole that keeps data brokers from accessing your updated address. When you fill out the online form to change an address, you can indicate a temporary change that provides six months of forwarding that can then be extended for another six months. That information, unlike the changes marked as permanent, is not included in the master list sold to data brokers."

And the online link for online change of address with the loophole:

Yes, but will they fail to forward the mail as reliably as they fail to forward permanently forwarded mail?

Correct.

(I've mentioned the temporary forwards tip elsewhere in the thread myself.)
