Use the list with caution. Most appear to be accurate, however there are notable omissions. For example, see Canada who are also regulated by the CWTA, and it is listed as only the CRTC. USA is listed only as the FCC when in a premium SMS context, you need to pay more attention to MMA Global's Best Practice Guidelines.
Similarly the APCC maintain a list of Asian regulators via the above link.
To ensure you adopt the correct regulations, use these lists in conjunction with the country listings in our Regulations and Market Data forums.
