## Availability

## What it does

This component represents a US Employer Identification Number (EIN).

It allows the user to enter an Employer Identification Number in the format `12-3456789`, with or without the dash.

* The user input is sanitized to remove any non-digit characters.
* The user input is validated:
  * to ensure that it contains exactly 9 digits, otherwise the field value is considered invalid
* The value is formatted as `12-3456789` when displaying the value.
* The value is stored in the database as a string of 9 digits including two separator dashes, for example `12-3456789`.

*NOTE: Storing the value with dashes is a design choice which seems to match the most common usage.*

Unlike the [US Social Security Number (SSN)](/form-runner/component/us-ssn.md), the EIN does not have any additional options for obscuring or revealing the value, as it is considered less sensitive than a Social Security Number.
