Area Code 584 – Zella

Geographic Overview

Area code 584 is a geographic National Destination Code (NDC) assigned to the town of Zella, located in the Jufra District of central Libya. Zella is a small desert oasis settlement, historically significant as a key stop along trans-Saharan trade routes. The code serves the town and its immediate surrounding rural areas, which are sparsely populated and primarily engaged in agriculture and oasis-based activities.

Dialing Formats

When calling a landline in Zella from within Libya, subscribers use the national trunk prefix 0, followed by the area code 584 and the local subscriber number. The complete national format is: 0 584 XXX XXX (where X represents the local digits). For international callers, the country code for Libya is +218, and the leading trunk prefix '0' is omitted. Thus, the international dialing format becomes: +218 584 XXX XXX. For example, a local number might be dialed as 0584 123 456 from within Libya, while international callers would dial +218 584 123 456.

Caller Instructions

• Local callers (within Libya): Always include the trunk prefix '0' before the area code when dialing from a different city or mobile network. For calls within the same exchange, local numbers may be dialed without the area code, but this depends on the operator's local dialing rules.
• International callers: Replace the trunk prefix '0' with the international access code (e.g., 00 from most countries) followed by Libya's country code +218, then the area code 584 and the subscriber number. Do not include any leading zeros.

Network and Regulatory Context

Libya's numbering plan follows ITU-T E.164 recommendations. Geographic codes like 584 are allocated to fixed-line services, primarily provided by the state-owned operator Libya Telecom & Technology (LTT). The country has not implemented number portability for geographic fixed-line numbers to a significant extent, so the code remains tightly associated with the Zella exchange. Mobile networks use separate non-geographic prefixes (e.g., 91, 92, 94), so this code is exclusively for fixed telephony.

Practical Considerations

Due to Zella's remote location, fixed-line infrastructure may be limited, and some residents rely on mobile or satellite services. However, for businesses or government offices operating in the area, the 584 code provides a stable geographic identity. When dialing from abroad, be aware that international call tariffs to Libya may vary, and some VoIP services might restrict calls to certain Libyan number ranges. Always verify the current dialing procedures with your service provider if you encounter issues.
