Vendor Registration

Register through the Vendor Portal to receive alerts to procurement opportunities and submit bids/proposals. Vendor registration is free.

In order to enter into contract with Miami-Dade County, a firm must be fully registered.

Note: Vendor registration requires a valid email address.

Review the following list of required documents prior to completing your registration:

  • Miami-Dade County current Local Tax Receipt (for vendors physically located within Miami-Dade County)
  • Certificate of Incorporation (if applicable)
  • W-9 (or applicable IRS form)
  • IRS letter 147C, verifying your business name and FEIN or any other preprinted IRS form issued by the IRS identifying you
  • Final Summary pages must be notarized and attached to the online vendor application (required to complete the approval of your application)
  • Miami-Dade County strongly recommends using a Federal Employer Identification Number (FEIN) rather than a social security number for vendor registration purposes. If you do not have an FEIN number, you can obtain one from at no cost
  • If you decide to use a social security number instead of an FEIN number, it may be used for the purposes of verifying identity, maintaining vendor database, payment processing and/or tax reporting to government agencies. In accomplishing these purposes, the number used to register with Miami-Dade County may be transmitted internally within the various departments and divisions of Miami-Dade County and externally to the Internal Revenue Service. This statement concerning the purposes for collection of a social security number is provided pursuant to section 119.071(5)(a)2., F.S.
