Why browse country codes by region?
Grouping countries by region helps call centers, exporters, SaaS platforms and global teams plan outbound campaigns more efficiently. Neighboring markets often share similar time zones, working hours and even dialing patterns.
For example, if you are targeting Eropa Barat, you may only need to adjust calling windows within one or two hours. If you are running a campaign in Asia Timur or across Amerika Utara, time zone differences become more significant and your agents’ shifts need to be scheduled accordingly.

FAQ: Regions and international country codes
How are regions defined on CountryCode.online?
We follow a practical mix of UN and telecom industry conventions, grouping countries into Africa, Asia, Europe, North America, South America, Oceania and the Middle East. For campaign planning, we also expose useful sub-regions such as the Caribbean and Central America.
Do country codes always reflect region?
Not perfectly. Many regions have characteristic ranges (for example, Europe is often +3x and +4x), but there are historical exceptions. That is why each region page lists individual countries with their exact calling codes and ISO identifiers.
Which region should I target for my campaign?
It depends on your product, language support and time zone coverage. Many teams start with one or two regions that have similar working hours—for example, Western Europe or Southeast Asia—then expand outward as their telephony infrastructure and staffing grows.
