Any benefit to memorizing A# and Naturalization certificate number?

[actblue]

I became a naturalized citizen in July of 2020. I already have my SSN memorized. Should I do the same for my A# and my naturalization certificate number? Is there any benefit in doing so?

No. If you really want to carry proof, I would recommend a passport card in addition to the passport. You can use card as proof of citizenship
Alternately, you can make a copy of the passport page and keep it in your wallet

The benefit to memorization is that if you petition an alien for immigration, you need you A# and N#. But you can just keep copies of these numbers on your phone, your computer and in an email message to yourself.
