FILE FORMATS FOR BID UPLOAD FEATURE FOR ALL ROUNDS
AU Docket No. 14-252
GN Docket No. 12-268
WT Docket No. 12-269
1. The Wireless Telecommunications Bureau (Bureau) today updates specifications for 
Auction System data file formats and provides a new set of sample data files for the clock phase of the 
broadcast incentive auction’s forward auction (Auction 1002).1 Of particular note, today’s updates 
include the specifications for data file formats and sample data files that will enable bidders to use the 
Auction System’s bid upload feature in all rounds of the auction.2 Other minor modifications have been 
made to the supporting text and file specifications.  A complete description of all modifications is 
included in the updated specifications.
2. The updated specifications and sample data files are available on the Auction 1002 
website (www.fcc.gov/auctions/1002) in the Data section.  The specifications provide for each data file an 
overall description of the file, the data fields that are included (with definitions of the data elements in 
each field), the data type, examples, and notes.3 Please note that for the sample data files the website 
provides a single ZIP file containing the individual CSV files, but the Auction System will provide each 
of the CSV files separately.  We emphasize that the updated sample data files we release today are for 
illustrative purposes only; they do not reflect any predictions or assumptions about the actual bidding in 
the auction, the number of rounds, or the outcome of the auction.
