parsing - Type-of-address of the sender number (SMS) -

I would like to know what kind of sender number is type-off-address for example , 91 type-off-address in pdu below: 9742020096F6400B 91 9742039333F7

91 means the format of the international phone number and I will add + before this number, sometimes I need to type-off-address Have to face such as D0 , C8 and so on. So what do they mean? Where can I find information about this? Thanks in advance.

- Update -

I got a program called PDUspy . It can recognize type-off-address . So I have found that D0 - alpha (ACS TS 03.38) and the number is shown as text, for example Nikolas . C8 - Customer number . But what do they mean and how to parse these numbers on the basis of these types?

TON / NPI information can be found in section 9.1.2.5. Address value (phone number) is left BCD coded, it is compounded with optional 'F', it is also swapped and then swapped.
