When does my subscription expire?
Information on subscription expiration
is hidden in the top line of your mailing label, thanks to changes we had to
make to avoid “Y2K” problems (remember Y2K?). Here’s how to find and
translate it:

The other information on the top line includes magazine ID (first two digits; CQ=01),
your subscription number (the long one) and, after the expiration date, the
issue date -- 2110 in our example would be October, 2001 (21=2001; 10=October).
If you have questions about your
subscription, please be sure to include your full mailing address, including ZIP
code in the US. Our system is set up to search most quickly on last name and ZIP
code, NOT on callsign. Please e-mail subscription inquiries to <circulation@cq-amateur-radio.com>.
