*TIN Validation*

# Catch bad TINs before the regulator does.

A single missing or malformed Taxpayer Identification Number can reject an entire filing. Label validates every TIN for format and jurisdiction structure the moment it’s collected — not the night before the deadline.

*Why it matters*

## One bad identifier, one rejected file

TIN errors are the single most common cause of FATCA & CRS rejections and regulator notices. Because Label checks every identifier at the point of collection, the errors get cured while you still have the investor’s attention — not in a deadline scramble.

### Format validation

Every TIN checked against the correct length, character set and structure for its jurisdiction.

### Jurisdiction rules

Country-specific TIN logic kept current — including jurisdictions that don’t issue TINs at all.

### Missing-TIN handling

Flag absent TINs and apply the correct reason codes so filings stay compliant where a TIN isn’t available.

### Point-of-collection checks

Validation runs as data arrives — investors fix their own errors instantly, not weeks later.

### Bulk validation

Run existing portfolios through validation in bulk to find latent errors before they surface.

### Cured & logged

Every correction tracked and timestamped for a defensible audit trail.

*How it works*

## Validation, not verification-after-the-fact

1. 1: **Collect**

   TINs captured through digital forms or bulk import.
2. 2: **Validate**

   Format and jurisdiction structure checked instantly.
3. 3: **Flag**

   Errors and missing TINs surfaced with reason codes.
4. 4: **Cure**

   Corrections captured and logged before filing.
