International mail processing centers (IMPCs) are postal facilities that play a crucial role in inter-operator mail processing of Russian Post, as they either form or receive items, or serve as transit centers for mail exchanged between other IMPCs. Each Russian Post IMPC has a clearly defined physical location, is managed or under the responsibility of a postal service, and processes a specific set of mail flows both domestically and internationally.
