North America, with 10-digit telephone numbers, is going to run out of area codes.

To quote the movie Casablanca, “Maybe not today, and maybe not tomorrow, but soon, and for the rest of your life.”

A change in how calls are dialed is going to have to be made.

This website proposes, and explains, that the “pain” of increasing the size of telephone numbers by 1 digit be started now, rather than later. I also explain why it should be 11 instead of 12, and why a “hybrid” system should not be used.

The North American (+1) telephone are includes the following countries and posessions: American Samoa; Anguilla; Antigua and Barbuda; Bahamas; Barbados; Bermuda; British Virgin Islands; Canada; Cayman Islands; Dominica; Dominican Republic; Grenada; Guam; Jamaica; Montserrat; Northern Mariana Islands; Puerto Rico; Saint Kitts and Nevis; Saint Lucia; Saint Vincent and the Grenadines; Sint Maarten; Trinidad and Tobago; Turks and Caicos Islands; United States; and United States Virgin Islands.
