Some of the Hilton corporate codes seem to be primarily domestic whereas others appear to be valid only for international properties. The code that you listed returns some very good rates at some domestic Hiltons. I have another IBM code,
001368083, that sometimes returns decent rates at international properties. As an additional complication, codes that work at Hilton and HGI typically do not work at any of the former Promus properties (Embassy Suites and Homewood Suites and Hampton Inn) and the Promus codes do not work at Hilton properties.
