UsSsnPattern class

Matches US Social Security Numbers (123-45-6789 or 123456789).

Format-only check — does not verify that the number has been issued. The mode field controls which input shape is accepted: ValidationMode.any (default) accepts either the fully-formatted or fully-unformatted shape, ValidationMode.formatted requires the dashes, and ValidationMode.unformatted rejects them.

V.string().taxId(
  patterns: [const UsSsnPattern(mode: ValidationMode.formatted)],
);
