1. A shipping label validation system comprising: one or more memory storage areas; and one or more computer processors that are configured to receive data stored in the one or more memory storage areas, wherein the one or more computer processors are configured for: (A) receiving a shipping label hash index that has been obtained by reading the shipping label hash index from a shipping label; (B) receiving un-encoded hash index verification information that has been obtained by capturing the un-encoded hash index verification information from the shipping label, the un-encoded hash index verification information comprising a combination of address data and non-address data and being received separately from the shipping label hash index of (A); (C) using the un-encoded hash index verification information to calculate a confirmation hash index, said calculating being performed without reference to the shipping label hash index and including: i. retrieving at least one hash key value from the one or more memory storage areas; ii. determining whether the retrieved at least one hash key value is valid; iii. inputting the at least one hash key value into a calculation tool, activation of said calculation tool being dependent, at least in part, upon inputting of a valid hash key value; and iv. calculating the confirmation hash index based on the at least one hash key value and the un-encoded hash index verification information; and (D) determining whether the shipping label is a valid shipping label, said determination including: i. determining whether the retrieved at least one hash key value is valid; ii. comparing the shipping label hash index with the confirmation hash index; iii. in response to the shipping label hash index and the confirmation hash index being the same and the hash key value being valid, determining that the shipping label is a valid shipping label; and iv. in response to at least one of the shipping label hash index and the confirmation hash index not being the same or the hash key value being invalid, determining that the shipping label is not a valid shipping label.
