Cannot send 5 digit sms from LG G4

[AC Question]

Please assist, I can't send any messages to a short digit number.
eg want to send "AB674" to the number 36697, but only receive a triangle error message and then a block stating "retry".

Doesn't recognise it as a real phone number?

Which SMS app?
