# Validated ID Numbers

The script `pci_postprocessing.lua` (see Configure Post Processing) includes steps to validate ID numbers that are found by Eduction. This improves accuracy by discarding results that match the pattern for a valid ID number, but cannot be genuine because they have an invalid checksum. The script increases the score for matches that have a valid checksum, because this is an indication that the match is more likely to be genuine.

The following tables list the entities that are validated.

Magnetic Stripe Data (`magstripe.ecr`)
pci/magstripe/context/magstripe | pci/magstripe/nocontext/magstripe | Validation implicitly validates the Primary Account Number (PAN) that is included in the magstripe data.

Primary Account Numbers (`pan.ecr`)
pci/pan/context/pan | pci/pan/nocontext/pan
