Interstate Mono Light  Suggested by Heron2001 
Letter Gothic Mono  Suggested by Lancon 

It seems it comes from a stamp.
The closest I could find is Letter Gothic Mono

I agree with Lipuro - but little bit closer is Interstate Mono Condensed - the 7 has a curve in it - that Letter Gothic doesn't.

I don't see the cond on myfonts - but I'm sure one exists...

I completely agree with you Heron2001
Even "1" has the curve
