FAQs (Frequently Asked Questions)


  • Technical Requirements

A computer with access to Internet and a web browser having JavaScript enabled. We support the following web browsers: Internet Explorer 7,8,9 and 10, Firefox 3.6, Chrome and Safari. The minimum screen resolution required to operate I2ES is 1280 x 768. Higher resolution screens with a resolution of 1920 x 1200 are recommended.



  • Specifications

  • As agreed with the Member States, development of I2ES is to be done in two phases. Upon conclusion of the development of the Phase 1 software, and after a second pilot testing by interested competent national authorities, I2ES was officially launched on 10 March 2015.

  • While the Phase 1 I2ES software does yet not comprise all features listed in the agreed requirements document, it provides a highly-usable initial system fully ready for deployment. I2ES covers all internationally controlled narcotic drugs and psychotropic substances.

  • Trade in preparations containing these substances is covered as well.

  • The balance of estimates/assessments does not include transactions that countries have carried out using their national systems prior to 10 March 2015, as I2ES does not have the records of these transactions.

  • If a participating country sends data to a non-participating country it will not receive a reply through I2ES. Only countries who are using I2ES can reply via I2ES and they will have the choice to respond or not.



  • Language

For the time being, I2ES will operate in the English language version only.



  • Main features of I2ES

  • I2ES is a web-based application designed to complement, but not replace, existing national electronic drug control systems.

  • I2ES serves as a platform for uploading and exchanging import and export authorizations between importing and exporting countries.

  • I2ES is able to link with other national electronic systems so that Governments will not need to adjust their own systems.

  • I2ES allows competent national authorities to generate and transmit import and export authorizations electronically and to download and print them.

  • I2ES enables countries without an own national electronic drug control system to electronically generate their own import and export authorizations.

  • A key feature of I2ES is the automatic checking of the quantity of a shipment against the latest estimate or assessment of the importing country.

  • In all cases involving excess imports or exports, a warning message is automatically sent to the authorities concerned.

  • I2ES provides an online endorsement function, which allows the authorities of importing countries to verify the quantity of a shipment arriving in their territory, and to endorse receipt of the shipment to the authorities of the exporting country.

  • I2ES automatically sends alerts, in real-time, to the authorities of the exporting country in all cases where the amounts exported are smaller than the amounts received.

  • All features of I2ES are in compliance with the provisions of the Single Convention on Narcotic Drugs, 1961 and the Convention on Psychotropic Substances, 1971.

  • I2ES was developed in close cooperation with Member States.

  • It is planned to make I2ES available also in other languages at a later stage.
