Are there areas where Twilio does not provide phone numbers?
Phone number coverage in US and Canada
Twilio currently offers phone numbers in all 50 states in the United States as well as all provinces and major cities in Canada.
In the US, we are able to provide phone numbers in almost all area codes. However, there are some exhausted area codes in major metropolitan areas that Twilio is unable to offer such as 602 (Phoenix) and 212 (New York). Also you might not find area codes that are relatively new in our inventory. An example of this would be 430 (Texas) numbers.
Canada also has a few exhausted area codes that Twilio often isn’t able to carry. Examples of such area codes include but are not limited to 416 (Toronto), 905 (Ontario) and 403 (Calgary) numbers.
While Twilio is trying to maintain a broad selection of area codes at all times, you can sometimes run into the issue where the area code you’re looking for is temporarily out of stock. If this ever happens, we recommend using overlay area codes as a workaround. You may find the complete list of area code overlays here.
Phone number coverage in the rest of the world
For phone number availability outside the US and Canada please consult our FAQ on the coverage of Twilio’s global numbers. Generally in countries where Twilio offers local phone numbers, you can find them in the top 5 to 10 major cities.
