The direct answer
An Employer Identification Number (EIN) is a nine-digit federal tax identifier assigned by the Internal Revenue Service to businesses and other entities that need one. It is commonly used on tax filings and legitimate business documentation.
An EIN identifies an entity for federal tax administration. It is not a business licence, credit rating, SAM.gov UEI or D-U-N-S Number, and those identifiers should not be used interchangeably.
Where a business may need its EIN
Businesses may need an EIN for federal tax filings, payroll, banking, vendor onboarding, certain applications and other transactions where the requesting institution has a legitimate need to identify the taxpayer.
The correct disclosure method depends on the transaction. Tax forms, secure onboarding systems and direct exchanges with authorized counterparties are more appropriate than exposing the number on an unrestricted public webpage.
Why DSDillon does not publish its federal Tax ID
DSDillon keeps its EIN off the public website. The IRS advises businesses to protect EIN information, and publication provides little verification value because a number displayed on a webpage does not prove that the visitor is dealing with the rightful entity.
Public verification policy
DSDillon publishes identifiers that are designed for public or institutional matching, including its UEI and D-U-N-S Number. Federal Tax ID information is supplied only through an appropriate secure business, tax or procurement process when required.
How a legitimate counterparty should verify tax identity
A customer, bank, payer or procurement team that genuinely needs an EIN should request it through the applicable tax or onboarding process. Depending on the transaction, that may include an IRS form, secure vendor portal or direct company documentation rather than a public web page.
