Army LRC National Stock Number Check

The Army LRC National Stock Number Check was a logistics lookup utility hosted on the Aberdeen Proving Ground Logistics Readiness Center's web server (lrcweb1.apg.army.mil). That server is now offline — the domain no longer resolves — and its underlying application appears to have been part of a broader Army requisition/item-lookup system that was formally retired and replaced. Army logisticians who previously used it should transition to i3Log, its official CAC-gated successor on the Army Vantage platform.

What it is

The tool ran on the same host (lrcweb1.apg.army.mil) that served the Army's i2Log application, which let users search requisitions by document number, DODAAC, or NIIN, and also served a separate CECOM equipment-search tool called PIE (Policy and Information Encyclopedia) searchable by NSN/NIIN, LIN, part number, or item name. Per Army PS Magazine (the official Army sustainment/maintenance publication), i2Log was scheduled to sunset and was extended to March 30, 2024, before being formally replaced.

Who operates it

The host server was operated by the Logistics Readiness Center (LRC) at U.S. Army Aberdeen Proving Ground, Maryland, which directs garrison logistics functions including supply, equipment management, and logistical support planning for the installation.

Access

The domain lrcweb1.apg.army.mil no longer resolves (DNS lookup fails), so the original URL is dead, not merely gated. The directory record's "public" access classification does not reflect reality: the underlying application (i2Log) required a Common Access Card (CAC). Its official successor, i3Log, is hosted on the Army Vantage platform at vantage.army.mil/i3log and requires CAC login plus Army Vantage registration for first-time users.

How logisticians use it

Army supply and logistics personnel used tools on this host to trace requisition status by document number/DODAAC and to look up item and NSN/NIIN data tied to CECOM-managed equipment. For authoritative, service-wide NSN/NIIN data (item name, CAGE, manufacturers, part numbers), the Defense Logistics Agency's WebFLIS and FED LOG remain the federal systems of record; i3Log and Army Vantage are the current Army-specific successors for requisition tracking.

Related systems

DLA's WebFLIS and FED LOG are the authoritative federal sources for NSN/NIIN data. i3Log (Army Vantage) is the direct successor for Army requisition lookups formerly handled by i2Log on this same retired host.
