SSN

Validates that a value is a US Social Security Number. Both the dashed and plain digit forms are accepted.

Configuration

Config flag	Type	Description
`ssn`	`boolean`	When `true`, requires the value to be a valid US SSN.

const form = useForm({
  initialValues: { ssn: '' },
  validationSchema: {
    ssn: { ssn: true },
  },
});

import { V } from 'formify-js';

V.ssn();

Scenario	Message
Value is not a valid SSN	`Must be a valid Social Security Number`

The ###-##-#### shape is enforced — with or without dashes.
Pair with the ssn formatter (format: "ssn") to auto-format the input as the user types — see Formatters.
Empty values pass unless required: true is also set.
