Grand Valley Identifiers

The Grand Valley Identifiers are a standard identification procedure for all children from the Grand Valley orphanages. Similar to the Numbering system used in Grace Field House, they are likely marked before they reach the farm. However, while the Grace Field House orphans' identifiers are on their necks, the Grand Valley children marks are across the chest. Mamas, Sisters, and Grandma like any other adult human in the Hierarchy of the demons, presumably also have an identifying number.

Understanding
The Grand Valley Identifiers consist of a single letter followed by a Roman numeral, then a sequence of 3 numbers, a dash, and a second 3 number sequence. It is so far not known how the identifiers can be decoded.
