North America region overview
North America is a diverse telecom region that includes large economies such as the United States, Canada and Mexico, as well as fast-growing markets in Central America and the Caribbean. The region uses a mixture of the North American Numbering Plan (NANP) with shared country code +1, and independent country codes such as +52 (Mexico) or +53 (Cuba).
For international callers, it is important to distinguish between NANP destinations (where the structure resembles a US or Canadian number) and non-NANP countries in Central America and the Caribbean. The table above lists the main North American countries and territories with their dialing prefixes, ISO codes and primary time zones, helping you plan customer support, sales or personal calls across the region.
North American sub-regions for call routing
Many businesses group North American destinations into sub-regions so that sales teams, contact centers and SMS platforms can manage time zones, languages and tariffs more easily. Below is a practical segmentation.
Core North America
United States · Canada · MexicoThe largest and most integrated telecom and economic area in the region. The United States (+1) and Canada (+1) share the NANP structure, while Mexico (+52) has its own country code and numbering rules. These markets account for a high volume of business and consumer traffic.
Time zones span from UTC−10 in Hawaii to UTC−3:30 in eastern Canada. Pay attention to daylight saving time changes.
Central America
Guatemala · Honduras · Nicaragua · etc.Includes Belize (+501), Costa Rica (+506), El Salvador (+503), Guatemala (+502), Honduras (+504), Nicaragua (+505) and Panama (+507). These countries link North and South America and are important for logistics, manufacturing and nearshoring services.
Most Central American countries use UTC−6 or UTC−5, which simplifies cross-border outreach in the region.
Caribbean Community & neighbours
Island states and territoriesCovers sovereign states such as Jamaica (+1-876), Trinidad and Tobago (+1-868), Barbados (+1-246), Bahamas (+1-242), Saint Lucia (+1-758) and others, as well as territories such as Puerto Rico (+1-787 / +1-939) and the British Virgin Islands (+1-284).
Most Caribbean destinations are in UTC−4 or UTC−5 and may or may not observe daylight saving time.
Atlantic & Arctic territories
Greenland · Saint Pierre and Miquelon · othersSmaller but strategic territories such as Greenland (+299) and Saint Pierre and Miquelon (+508) sit at the crossroads of North America and Europe. They may fall under European countries politically but are often grouped into North American dialing zones due to geography and routing.
These locations span time zones from UTC−3 to UTC+0 and can have specific roaming or tariff conditions.
Time zones across North America
North America spans a wide range of time zones, from the Pacific islands of the United States to Atlantic and Caribbean territories. Understanding the main bands helps you plan international calls and avoid contacting customers outside normal office hours.
Common North American time zones
| Zone | UTC offset | Example markets | Notes |
|---|---|---|---|
| Pacific Time | UTC−8 (UTC−7 DST) | US West Coast, western Canada, northwest Mexico | Important for tech, media and start-up hubs like Los Angeles, Seattle and Vancouver. |
| Mountain Time | UTC−7 (UTC−6 DST) | US Rockies, parts of Canada and Mexico | Less populous than coastal zones but significant for energy and logistics. |
| Central Time | UTC−6 (UTC−5 DST) | US Midwest, central Canada, much of Mexico, Central America | A key overlap zone between North America, South America and Europe. |
| Eastern & Atlantic Time | UTC−5 to UTC−3 | US East Coast, eastern Canada, Caribbean, Greenland | Best suited for same-day contact with both Europe and the Americas. |
Not all countries and territories observe daylight saving time. Always confirm local rules, especially when working with Mexico, the Caribbean or Central America.
Suggested calling windows into North America
The best time to call depends on your location and whether you are targeting the east, central or west of the continent. The examples below assume standard office hours (09:00–17:00 local time) for business contacts.
- From Europe: Late afternoon in central Europe (15:00–18:00 CET) overlaps well with morning in the US East Coast and early afternoon in Brazil and parts of Canada.
- From Asia-Pacific: Early morning in Singapore, Hong Kong or Beijing may coincide with late afternoon in the US West Coast, while afternoon hours align better with Central and South American markets.
- Within the Americas: Consider splitting campaigns by time zone (Eastern/Central vs. Mountain/Pacific) so customers receive calls within their local office hours.
- Caribbean & Central America: Many markets share similar time bands with US Eastern or Central Time, making cross-border coordination easier.
Dialing patterns & example calls into North America
North America uses two main dialing models: the North American Numbering Plan (NANP) with shared country code +1, and independent country codes for Central America and non-NANP Caribbean states. Understanding this distinction helps reduce failed calls.
Generic dialing formats
1) NANP countries and territories (USA, Canada, many Caribbean islands)
Example: calling a New York number from France: 00 1 212 xxx xxxx
2) Non-NANP countries (Mexico, Costa Rica, Guatemala, etc.)
Example: calling a Mexico City landline from Germany: 00 52 55 xxxx xxxx
UK → United States (mobile)
00 1 3xx xxx xxxx
00 (UK exit code) + 1 (NANP) + 3xx (mobile/area code) + subscriber number.
Germany → Canada (landline)
00 1 604 xxx xxxx
604 is an example area code for British Columbia. The structure is the same as calling the US.
France → Mexico (mobile)
00 52 1 xx xx xx xx xx
In some cases, Mexico mobile numbers require a “1” after the country code when dialled from abroad.
FAQ: Calling North American countries
Is there only one country code for the United States and Canada? +
Yes. Both the United States and Canada share the NANP country code +1. Many Caribbean islands and territories also use +1 with different area codes. To identify the destination, you must look at both the country code and the 3-digit area code.
Do mobile and landline numbers have different prefixes in North America? +
In NANP countries, mobile and landline numbers both use 3-digit area codes and 7-digit local numbers. The type of service is determined by the specific area code, not by a separate “mobile prefix” like in Europe or Asia. In non-NANP countries such as Mexico or Costa Rica, dedicated mobile prefixes are more common.
Why do some Caribbean islands use +1 while others have different country codes? +
Many Caribbean islands joined the North American Numbering Plan and share the +1 prefix with the US and Canada (for example Jamaica +1-876, Barbados +1-246). Others use separate ITU-assigned country codes such as +53 for Cuba, +52 for Mexico or +501 for Belize.
How can I store North American contacts to avoid problems when roaming? +
The safest way is to store all numbers in full international format, starting with the plus sign (+), the country code, area code and local number — for example +1 415 xxx xxxx for San Francisco or +52 55 xxxx xxxx for Mexico City. This helps your phone and messaging apps route calls correctly when you travel.
Where can I find detailed formats for each North American country? +
Each country has its own detail page on CountryCode.online, including example numbers, emergency numbers, mobile prefixes and time zone information. Start from the Countries directory or use the homepage search to navigate directly to pages like United States, Canada or Mexico.
