FEIN Verification

Verifying or changing the Federal EIN of a business account

Federal EIN Verification or Update

If your customer forms a new legal entity then we'll need to update the entity's Federal EIN in Sila's databases. Likewise, in some cases a potential customer can fail ID verification due to their FEIN. The following is a list of documents we can accept to verify or update your customer's FEIN.

A clear photo of one of the following documents:

  • IRS EIN verification letter
  • IRS Tax return
  • IRS Form W-9
  • IRS Form SS-4

❗️

Document requirements

  • We need to see all four corners of the document, and the business name and EIN you are verifying must be clearly visible.
  • Original PDFs are best.
