H4 visa stamped with 5 year validity-mistake or valid?

Hi all,
I have a h4 visa stamped in 2018 and it was issued for 5 years (Expiring in 2023), not sure if it was a mistakenly issued for 5 years (Assumption here is visa is typically issued for 3 years). My question is if I can re-enter US on that visa? Anybody with similar situation was able to re-enter US?

Thanks

My guess is that the CBP officer at port of entry will only look at the expiry date and most likely let you in.

You may want to verify your visa validity with the consulate that issued it.
