It won't allow me to submit the form, and it highlights it as an error, but I can still enter it. Using a maxlength means I can't even enter 12345, and it's obvious that it will only accept 4 digits.

Numeric codes are almost certainly actually type=text, with a
pattern="\d+" or the like.  If the first digit is allowed to be 0,
it's not type=number.  Note that we have the inputmode attribute
to still indicate that the on-screen keyboard should be numeric rather
than alphabetic.
