IAP Receipt ASN.1 field type for offer_code_ref_name

According to this LINK, i can read IAP Receipt Fields.

For example product_id has type number 1702.

So what i am looking for is offer code field type number with named offer_code_ref_name as stated HERE

But the problem is i didn't find it anywhere. Any idea?

I have exactly the same question for field receipt_type.
