AC6 (Atlantic Council document prefix)

AC6 is a prefix that identifies Atlantic Council documents. NATO's Glossary of NATO Acronyms and Abbreviations (AAP-15) lists it as "Atlantic Council" with the note "Prefix identifying Council documents." It belongs to the reference system NATO uses to label the papers produced by the North Atlantic Council and its subordinate bodies. You can read the entry in the AAP-15 glossary.

The glossary prints the term as AC6, without a slash. NATO's archival catalogues write the same series as AC/6. Both forms point to the same Atlantic Council document prefix. Canadian suppliers are most likely to meet the term in NATO reference material or archival records, not in a Canadian tender notice.

How NATO document prefixes identify a paper

NATO assigns each official document a reference that shows what kind of paper it is and which body issued it. NATO's page on publicly disclosed NATO documents explains the lettering used in its document series. A stands for Agenda, D for Document, M for Memorandum, N for Note and R for Record.

A prefix such as AC6 works at the level of the issuing body. It tells a reader that the paper comes from a Council-related series and not from another NATO committee. Reading the prefix correctly helps a researcher place a document in the right archive series.

AC/6 and the Working Group on Security in NATO

In NATO's archives, AC/6 is the series of the Working Group on Security in NATO. The North Atlantic Council's Deputies established the group on 11 June 1951. Its series holds documents, notes, records and related papers about NATO's security system.

This history explains why AC/6 appears in archival finding aids. It is a record of how NATO organized its own security arrangements in the early 1950s. The prefix does not name a current programme, standard or contract vehicle.

AC6 and AC/6: one series, two spellings

• AC6 is the form in the AAP-15 glossary, where it is defined as an Atlantic Council prefix for Council documents.
• AC/6 is the form in NATO archival records, where it labels the Working Group on Security in NATO series.

When you search NATO archives, try the slashed form. When you check an acronym list, expect the unslashed form. NATO's official terminology database is maintained by the NATO Terminology Office within the NATO Standardization Office. It is available through NATO's terminology portal.

What AC6 means for a supplier bidding on Canadian public contracts

AC6 is not a supplier qualification, a security requirement, a deliverable or a contract condition in the Canadian guidance reviewed. You do not need to quote it in a bid or register under it.

The term can still reach you through NATO work. CanadaBuys carries tender notices from the NATO Support and Procurement Agency, as described in its guidance on searching tender opportunities. Canadian businesses can bid on eligible NATO opportunities. National Defence explains the process in its page on how to do business with NATO.

If a NATO document you are reading carries an AC6 or AC/6 reference, treat it as a label for the issuing series. Take your actual obligations from the solicitation itself. Public Services and Procurement Canada states that organizations bidding on NATO opportunities must meet the security requirements listed in the procurement documents. See its page on NATO agreements and contract security requirements.
