Codes 0, 6, 7, and 8 are all confirmed matches. Codes 2 and 3 require W-9 outreach. Codes 1 and 4 are data quality issues fixable before re-submission.

Result Distribution

By volume

TIN Type Distribution

EIN vs SSN vs Unknown
A high proportion of TIN Type 3 (Unknown) increases processing time and reduces diagnostic detail. Use Type 1 (EIN) or Type 2 (SSN) where entity type is known.
