# Migrating `tin_matched` field from enum to boolean

> March 7, 2024

The `tin_matched` field has been migrated from being an enum with values `NO_MATCH` or `EXACT` to a boolean to reduce confusion.

`tin_matched` was previously an enum to align more closely with the `business_name_match` and `business_address_match`, but since there is no `SIMILAR` match for the `tin_matched` field, it makes more sense to treat it as a boolean - since the TIN is either a match by the IRS or not.
