Solicitation Numbers – What Do They Mean?


Classify this information as not exactly essential, but good to know…


The solicitation number is made up of several parts.

  • The first 6 digits (a mix of letters & numbers) identifies the specific department, agency and office issuing the solicitation. This is known as the Activity Address Code – AAC – or DoDAAC for Dept. of Defense contracts.
  • The second two digits identify the fiscal year the bid is issued
  • The next letter indicates if the solicitation is an Invitation for Bid (B); a Request for Proposal (R); a Request for Quote (Q), and so on.
  • The final four numbers are specific to that particular solicitation


For example:

SPM8ED -18 – Q – 0123
Buying Office – Fiscal Year – Request for Quote – Solicitation ID Number
