Reference: 8621-C12-02/00

Correction to public notice CRTC 2000-52 dated 7 April 2000

Paragraph 4 of the above public notice should read as follows:
The theoretical capacity of the current plan is 6.4 billion numbers. There are 800 area codes, each capable of supporting 800 CO codes, each of which has 10,000 telephone numbers. The actual capacity is less than stated as certain digit combinations are not available for use as area codes or CO codes, such as 9-1-1. Other numbers are used for different applications such as 800, which may cause customer confusion if they were assigned as a CO code.
