In the SMS to be sent for registration, it appears that we can choose various code, such as P1 (HLB Website), P3 (SMS Blast), and so on.
What is the purpose of such codes?
In my opinion, HLB wants to know how we are aware of the contest, either by website, e-mail and so on.
I am not sure about this, but
is it possible that HLB wants to allocate the 200 monthly winners, based on source of the promotion? Example:
P1, HLB Website: 10 Credit Card Winners, and 10 Debit Card Winners, per month.
P2, HLB Facebook: 10 Credit Card Winners, and 10 Debit Card Winners, per month.

P10, Social Influencers’ Post: 10 Credit Card Winners, and 10 Debit Card Winners, per month.
The terms and conditions are vague about this allocation.

you may be right but you will never know.
