Cheez-It is halal by ingredient — the maker confirms the cheese uses microbial (not animal) rennet — and the Original and Hot & Spicy varieties are IFANCA halal-certified. Only a handful of flavours with added meat or unusual seasoning need an individual check; the core range is halal, unlike many cheese snacks that rely on animal enzymes.

The short version
Cheez-It uses microbial rennet, not animal enzymes, and its Original and Hot & Spicy varieties are IFANCA halal-certified — so it is a reassuring case.
Why Cheez-It is different from other cheese snacks
Many cheese snacks (like some Cheetos and Doritos) use animal-derived cheese enzymes. Cheez-It's maker has confirmed the cheese is made with microbial (yeast-based) rennet — no animal enzymes — which is halal. That is the key distinction.
Certification
The Original and Hot & Spicy Cheez-It varieties are certified halal by IFANCA. Other flavours are not all individually certified, but the microbial-rennet cheese base means they are halal by ingredient — check any flavour with added meat or unusual seasoning.
