SUMMARY
Per ITU-T Operational Bulletin 751, the Czech Republic (country code +420) announced that effective September 22, 2002, the Czech Republic will change to a flat nationwide numbering plan without city codes. The &quot;0&quot; long-distance prefix will no longer be used. This article describes how to configure Windows 98, Windows NT 4.0, Windows 2000, and Windows XP to reflect this change. This change has already been made in Windows XP Service Pack 1 (SP1)



MORE INFORMATION
WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

To reflect the dialing change on a computer that is running Windows 98, Windows NT 4.0, Windows 2000, or Windows XP, use the following procedure to change the REG_SZ LongDistanceRule value from &quot;0FG&quot; to &quot;G&quot;. Follow these steps, and then quit Registry Editor:  Click Start, click Run, type regedit, and then click OK. Locate and then click the following value in the registry:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Telephony\CountryList\420\LongDistanceRule

 On the Edit menu, click Modify. Type G, and then press ENTER.
