Help developing film shot around 5 years ago without labels

edit- by labels, I mean to say my physical handwriting on the canister 

I have various 35mm films shot around 5 years ago. Only one of them was appropriately marked on the canister, tri-x, shot at 400. But I did not label the second film for some reason. There is a high possibility that I shot it at a higher ISO, maybe 800, I dunno! Might even be at 400. I use to develop with diafine back then, but not always, so not sure how I shot it.

what is the best thing to ask for when I send the film to a lab? Tell them to develop as 800? Or better to just process at 400, even if it was shot at higher ISO? My intuition tells me it’s safer to have the film pushed, but I dunno for sure 

For what it’s worth, there’s probably nothing important on the films. 
 

I also have around 4-5 rolls of film that are all now 5 years old, is it correct that overexposing a stop the way to go? 

Thanks !

throw them away , then ...

😉

or

process in the 'overexpose' side( 400 film as ISO 200 or less)

Just process them normally, If you are doing it yourself do one first and see how it comes out then increase or decrease the development for the next one. If anything they will have lost a bit of contrast over time, if they have not been stored in the fridge, so increase the development a bit to compensate.

if you are sending them to a lab to be developed you won’t have any control over what they do.

The unused ones should be ok to use, just try one and see, I have plenty of five year old film.

Thanks for the replies!

Has anybody here used citizen photo in Portland? Any recommendations?

If you are completely in the dark about film stock and speed used, either Diafine (if you still have any) or Rodinal 1+100 semi-stand for an hour would be my suggestions. The latter seems to work for anything.
