The multilingual NATO Master Catalogue of References for Logistics (NMCRL) exists as a real time database on the Internet (NMCRL-WEB) and as an offline database for use on any PC not connected to the Internet (NMCRL-OFFLINE). It is a valuable tool for logisticians and manufacturers in every nation, providing information about materiel and significant business intelligence gathered from the databases of the National Codification Bureaux in the NATO Codification System (NCS) user countries (NATO and AC/135 sponsored countries). Although the NMCRL was originally designed for use by NATO logisticians, has proved to be an invaluable tool for non-NATO logisticians and civilian companies. The product now has worldwide distribution. In addition to ease of use and rapid search and extract features, the main advantage of the NMCRL is that it contains all of the NATO Stock Numbers assigned by the NCS countries. As the primary logistics tool for NATO and AC/135 sponsored countries, the NMCRL provides a catalogue of the materiel they use. The NMCRL is also extremely valuable to any civilian company wishing to do business with many armed forces worldwide. The NMCRL is available on an annual subscription basis.

The NMCRL includes the following data used by the armed forces of the NCS countries (NATO and AC/135 sponsored countries):

  • 17.6 million active NATO Stock Numbers (NSNs)
  • 38.8 million manufacturer or vendor Reference (Part) Numbers
  • 02.8 million active manufacturers and vendors (NCAGE code, names and addresses)
  • 30.0 million User Registrations
  • 12.1 million NSNs with Characteristics Data display NMCRL-WEB only
  • 03.9 million NSNs with Packaging Data display NMCRL-WEB only
  • 15.5 million NSNs with Custom Codes (HS & Schedule B) display NMCRL-WEB only
  • 13.4 million NSNs with Common Procurement Vocabulary (CPV) Codes display NMCRL-WEB only


NMCRL-WEB is a web-based multilingual application for querying codification data.

The application is available on-line 24/7 anywhere in the world via a high-speed Internet connection: all you need is a user ID, a password and an up-to-date browser (IE and Firefox supported).

Multi-user licences are available.

Beyond the additional features and data, one major advantage of using NMCRL-WEB online is that no periodic updates need to be installed.

NMCRL-WEB is updated on a daily basis.

NMCRL-OFFLINE is a multilingual application for screening codification data without an Internet connection, but which provides fewer features and fewer types of data than NMCRL-WEB.

The application installation file (in ZIP format) is downloadable to any storage device on a PC connected to the Internet. After downloading, the offline application is ready to be installed on any PC running Windows and can also be shared on a network, provided the necessary licences have been purchased.

An updated version of NMCRL-OFFLINE is released every two months.

Both NMCRL-WEB and NMCRL-OFFLINE feature “Basic” and “Advanced” inquiry modes. The Basic mode is specially designed for non-experts and mostly displays plain text instead of NCS codes. The Advanced mode is intended for codification experts and includes (NMCRL-WEB only) a “Query Builder” functionality for the Item of Supply and NCAGE modules.

NMCRL can be queried interactively or in batch mode:

1. Interactive mode

The interactive mode enables users to query based on search criteria. Queries on any combination of data elements is only possible in the NMCRL-WEB application. The results are displayed on-screen. Results can be displayed in detail, printed out or saved and a batch process can be run. The following interactive search modules are available:

  • Item of Supply
  • Characteristics NMCRL-WEB only

2. Batch mode

Using the batch mode, codification data can be extracted from the NMCRL database by using a list of criteria (search keys) recorded in an existing file or by generating a new list (in lieu of making a one-by-one search in the interactive program).

This method was developed mainly to facilitate effective and friendly extraction of codification data by users.

Predefined batches limit the number of actions required to extract simple data and facilitate the majority of frequent searches on codification data.

Batch results can be saved in various formats or printed out. Batch instructions can be entered either by using the keyboard or by importing data from external files. Conditional matches are possible. Maximal limit per batch input/output is 10.000 line items.

Inquiry Modes

As the NMCRL application is used not only in NATO member countries but all around the world, particular attention has been paid to linguistic needs.

The information contained in the NMCRL reflects the contents of the information held in the NCS countries’ national files. NMCRL information is in coded format, but majority of data elements can be de-coded. De-coded information and data element labels change depending on the interface language selected. All of the translations are provided by the National Codification Bureaux of the NCS countries (NATO and AC/135 sponsored countries).

In NMCRL-WEB currently 15 different language interfaces are selectable (3 language interfaces in NMCRL-OFFLINE: English-French-German).

If you have any questions regarding either NMCRL-WEB or NMCRL-OFFLINE you might find the answer below, if not, do not hesitate to contact us via

  • Only a small number of the countries share their management data via NMCRL. The majority of NATO Codification System countries (i.e. NATO and AC/135 sponsored countries) do not exchange that data internationally. In most cases, management data contained in the NMCRL database usually relates to US NSNs.

  • The technical characteristics associated with NSNs are not included in the batch module output fields because that data cannot currently be batch processed owing to the complexity of the Master Requirements Codes (MRCs). Moreover, disclosure of technical characteristics to private companies is prohibited by certain countries.

  • The batch processing module is based on “Advanced” mode querying. The “procurement status” field displayed in basic mode results from a simplification of the reference number related codes used in the “Advanced” mode. To see whether an item is procurable using batch mode, extract the RNCC/RNVC data elements then look up the meaning of the combinations in help file “EN-12”.

  • NMCRL is used by individuals, small businesses and large international holdings with different subscriptions in various locations around the world. Because large organizations can have different types of subscription (single user, up to 5, up to 20), management of users is left to the discretion of the Master Administrator, who can attach or detach any other user from his/her subscription.

  • An item of supply can be identified with an Approved Item Names (AIN) or a Non-Approved Item Name (NAIN). Every AIN is linked to a corresponding item name in ACodP-3, the multilingual catalogue of NATO Approved Item Names, but this is not the case for NAINs. When the item is codified, if an AIN is used in Segment A then the corresponding ACodP-3 item name will be displayed in the “Item Name (ACodP 3)” field (if the user interface is English, the item name will be identical in both fields). If a NAIN is used in Segment A, no ACodP-3 item name will be displayed.

  • The Query Builder was designed to facilitate searches in the Item of Supply and NCAGE modules by using simple queries. It replaces the Boolean operators previously used to combine search criteria.

  • The only browsers fully compatible with NMCRL are Internet Explorer (IE) and Firefox. While other browsers may be used, there is no guarantee that all of the functions will work correctly.

  • The subscription form provides the VAT number of NSPA.

  • Yes, but only one user at a time can connect to the application. If second user tries to connect simultaneously, access will be denied.

  • The NMCRL subscription lasts 1 calendar year starting the 1st day of the month in which the subscription has been requested.

  • NMCRL Subscription prices are valid through all the calendar year from 1st January till 31st December. Prices are adjusted at the very beginning of the calendar year. Usually there is an increase of 2.5% yearly to cover the inflation rate.

  • Yes, NSPA sends to every NMCRL subscriber a document called “Invoice Paid”.

  • An NMCRL Master Administrator login is generated for the person taking out the NMCRL subscription. The Master Administrator is responsible for managing the users of his/her subscription and communicates with NSPA. Generic logins are intended for all other users of the subscription and are created by the Master Administrator.

  • NMCRL is a database containing all NSNs worldwide. FED LOG consists just US NSNs and NSNs used by US, but on the other hand there is more information in compare to NMCRL (e.g. management data, prices, etc.)
