Thank you for the opportunity to help you with your question!

Possibilities

Alphabets (A-Z) = 26

First digit (1-9) =9

second,third and fourth digits (0-9) =10 each

Therefore the possible number that can be formed from this combination is,

26*9*10^3 = 234,000

Please let me know if you need any clarification. I'm always happy to answer your questions.
