What is the 221 Country Code?
The 221 country code is the international dialing code assigned to Senegal, a West African nation known for its rich cultural heritage and vibrant economy. This three-digit numerical code serves as Senegal's unique identifier within the global telecommunications network, enabling seamless international communication. When making calls to Senegal from abroad, the 221 code must precede the local number to ensure proper routing through international telephone networks.
Understanding the structure of international dialing codes requires examining how these numbers are allocated and utilized. The 221 code falls under the North American Numbering Plan Administration (NANPA) zone, despite Senegal's geographical location in Africa. This allocation demonstrates how country codes are assigned based on international agreements rather than geographical proximity. The International Telecommunication Union (ITU) oversees this allocation process, ensuring each country receives a unique identifier that facilitates global communication.
Technical Functionality of the 221 Code
The 221 country code operates within a sophisticated global telecommunications infrastructure:
- It serves as the primary identifier for routing international calls to Senegal
- Enables proper billing and tracking of international communication
- Facilitates international emergency services coordination
- Supports global business operations and international trade
These functions highlight the critical role of country codes in maintaining efficient global communication channels.
Historical Background of Country Codes
The development of international country codes traces back to the mid-20th century when global communication needs began to expand rapidly. The International Telecommunication Union (ITU), established in 1865, played a pivotal role in standardizing these codes through its E.164 numbering plan. This comprehensive system assigned unique numerical identifiers to each country, laying the foundation for modern international dialing.
The allocation of the 221 code to Senegal occurred during the early phases of African nations' integration into the global telecommunications network. This assignment reflected Senegal's growing importance in international communications following its independence in 1960. The country's strategic position along major maritime routes and its stable political environment contributed to its selection for this particular code within the numbering plan.
