This is a surprise:
It was time for me to submit another temporary change-of-address /forwarding order.
The USPS wants you to do it online.
So I started online, only to find that a new requirement has been added.
Unless you have a working mobile phone account,
you MAY NOT submit an order to have your mail forwarded.

I have a little flip phone with a cancelled account.
Now it seems that the mobile phone is part of the means
for verification of identity.
It has come to this . . .
