The following is the list of dozenal prime numbers and their equivalence to decimals, up to 400 in dozenal (576 in decimal). The third column lists if the number in the first column is P (prime) or C (composite) if that number is represented in decimal, while dozenal numbers that contain X and/or E are left blank as those digits don't exist in decimal.

Unlike the decimal system, some dozenal, including the first five, numbers ending with 5 are primes, while all dozenal numbers ending with 3 or 9 are composites as they are all divisible by 3. As a result of the absence of numbers in the first column ending with 3 or 9 (except for the single-digit 3) and the presence of those ending with 5, there are more dozenal prime numbers when if represented in decimal are composites than are primes, outnumbering 42-24.
