A code sent to the wrong kind of number is money and trust spent for nothing. Look it up first.
Number lookup tells you what a number is, who carries it and whether it can be reached, before you send a thing.
Three answers per number.
Line type, carrier and reachability. Enough to decide what to do before any code goes out.
Is it a phone that takes messages?
Which network the number sits on.
Whether a message can get there.
Only send to numbers that can receive.
Number lookup checks line type, carrier and reachability before a code is sent, so the numbers that cannot receive never cost you a send.
