Abstract: Postage pricing data may be determined and reported in a uniform manner from data files. The data files may be provided to a vendor and include postage pricing data, mailing attribute data and other data for locating the appropriate postage. To obtain postage pricing, a number of attributes associated with a user's mailing are identified. A first data file may be searched using the attribute data. A key is accessed from the first data file based on the attributes and then a second data file is searched using the key and a pricing structure. The postage price for the mailing may then be retrieved from the search of the second data file.
