Business Tax Identity
What Is an EIN and Should a Business Publish Its Tax ID?
Understand the IRS Employer Identification Number, where businesses use EINs, and why DSDillon does not publish its federal Tax ID on the public website.

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, use the applicable IRS form, secure vendor portal or direct company documentation.
Treat the EIN as a tax-administration identifier, not a public trust badge.
The IRS uses the Employer Identification Number to identify businesses and other entities for federal tax administration. The EIN application also requires a responsible party who ultimately owns, controls or exercises effective control over the entity and its funds or assets. That requirement is separate from public marketing or vendor-verification claims.
A counterparty that legitimately needs the number can request it through the appropriate tax, banking, payroll, procurement or vendor-onboarding process. Publishing an EIN on an unrestricted webpage does not establish that the person viewing the page is dealing with the rightful business, and it creates no equivalent to checking an official entity record.
- Use the EIN for federal tax and legitimate institutional processes that require it.
- Use SAM.gov UEI information for federal entity identification and D&B identifiers for D&B business records.
- Keep tax identity, business registration, licensing and commercial credit identifiers conceptually separate.
What DSDillon publishes instead
Public verification pages can use identifiers designed for public or institutional matching, together with corporate registration details and official-source links. Tax information can be supplied through a controlled process when a payer, bank or procurement team actually requires it.
