β 14y agocombining the 26 letters with the 10 digits you have 36 possible characters to choose from to go into 16 slots. Grab the nearest scientific calculator, or use Google or whatever you like, and use the permutation function nPr, inputting 36P16 you get 1.529x1023 different possible combinations to 4 significant figures.
Alternatively if you don't have the use of the nPr function you can use the formula n!/(n-r)! where n is the characters available and r is the amount of slots they have to go in.

No. An alphabet consists of only letters. A phoneme is a unit of language which has meaning. Letters, numbers, and symbols are all phonemes. There are dozens of phoneme types and subtypes. For instance, within letters you have consonants and vowels.
Just use letters and numbers, no symbols.
Letters are not numbers. Not all letters in the alphabet represent Roman numerals though some letters do.
it is 26
In California, for example, the first digit of a standard plate is a number, followed by 3 letters, and then three numbers. There are 26 letters in the alphabet, so there are 26 raised to the 3rd power combinations, or 26 * 26 * 26, which is 17,576 possibilities just of the 3 letters.

Zero. The alphabet consists of letters only. There are no numbers in it.

A code is a secret way of writing. A simple code, for example, would be to use the numbers 1-26 as they correspond to the letters of the alphabet, and then write words with the numbers instead of letters.

The NATO phonetic alphabet doesn't have any codewords for numbers, only for letters of the alphabet.

720 is the number of ways to combine three known letters and three known numbers.For example, the letters A, B & C and the numbers 1, 2 & 3. The total combinations of these 6 characters is:(6 options)*(5 options)*(4)*(3)*(2)*(1) = 720.However, if the three numbers and three letters are unknown and any number or letter is possible, and repeated numbers or letters are acceptable (such as with a license plate), then the total possibilities for each "space" are multiplied together:(26 possibilities)*(26 possibilities)*(26 possibilities)*(10 possibilities)*(10 " ")*(10 " ") = 17,576,000 combinations.That is, there are 26 letters in the alphabet and 10 numbers (0 thru 9).This is assuming that three of the six spaces spaces are reserved for letters and three spaces are reservedfor numbers.If the combination can be any three letters and any three numbers where different combinations are made by changing whether each space contains a number or a letter, then the answer becomes a product and sum of different choose functions and is much more complicated...
