Systems and methods which provide for allocation of tokens, such as may be used for tracking number dissemination, for shipment document processing are described. Embodiments operate to allocate tokens to the various shipping document processing systems for their use by the respective document processing systems. The various shipping document processing systems may be enabled to independently perform shipping document processing for extended periods of time (e.g., days, weeks, etc.) using their respective allocations of tokens, such as to use the tokens, including reuse of the tokens over time, without overlap (e.g., without introducing overlapping instances of tracking numbers). Logic of shipping document processing systems record use time information (e.g., a date and/or time of use of a token or tokens) in association with their use of tokens of their allotment, wherein the use tokens from the allocations is in accordance with last use time information.
