Hmm, I received mine last year & have an expiration date of 7/31/3029
The duration of aircraft registration certificates has been extended up to 7 years. The Registry will be issuing revised certificates in batches based on the former expiration date. For verification purposes, even though the expiration date on the registration certificate may not match the expiration date in the FAA Aircraft Registration database, any registration certificate displaying an expiration date of January 31, 2023 or later is still valid. This applies to all foreign Civil Aviation Authorities or anyone else with a verification need.
WOW, any plastic you have in your plane will decompose before your registration expires.
How long does plastic take to decompose?
Plastic can take anywhere from 20 to 500 years to decompose, depending on the material’s structure and environmental factors such as sunlight exposure.
As a matter of fact, if you go to the FAA web site (‘N number lookup’), there is a note in red that says if the web site shows you are unexpired, you’re good to fly, even if your paper certificate has expired!

I wasn't the only one confused by this after talking to some peeps around the airport...
Well, there's the explanation. LOL! I wish I had a dollar for every piece of flat-out wrong "information" I've heard from old airport dogs. And some not-so-old ones.
