Area Code 58 – Oranjestad & Main Island Area

Geographic Coverage and Administrative Jurisdiction

Area code 58 is a geographic National Destination Code (NDC) assigned to the capital city of Aruba, Oranjestad, and its immediate surrounding metropolitan area on the main island. This allocation follows the ITU-T E.164 numbering plan for Aruba (country code +297), where the full national significant number (NSN) is seven digits. The 58 prefix is used for fixed-line PSTN services, including traditional copper lines, fiber-to-the-home (FTTH), and fixed wireless access (FWA) connections that are registered to physical addresses within the Oranjestad service area.

Oranjestad serves as the administrative, commercial, and cultural hub of Aruba, hosting the Parliament building, the central bank, and major retail districts. Consequently, the 58 code covers government offices, financial institutions, hotels, and residential neighborhoods in the capital and adjacent districts such as Madiki, Rancho, and Ponton. Suburban developments along the main highway toward the airport may also fall under this code, though some outlying areas use other geographic codes.

Dialing Formats and Caller Instructions

For local callers within Aruba, the 58 prefix is dialed as part of the seven-digit number. For example, to call a fixed line in Oranjestad, a local caller would dial 58X-XXXX (where X represents the subscriber digits). No trunk prefix (such as '0') is used for domestic calls in Aruba.

International callers must dial the full international format: +297 58X XXXX (or +297 58XXXXX). For instance, to reach a number in Oranjestad with the local number 583-4567, an international caller would dial +297 583 4567. When dialing from a mobile phone, the plus sign (+) is typically used to denote the international access code, but it can be replaced with the specific exit code of the originating country (e.g., '011' from the United States, '00' from most European countries).

Numbering and Overlay Considerations

Aruba's numbering plan does not currently employ area code overlays. Each geographic code is unique to its region, and the 58 prefix is exclusively used for Oranjestad and the main island area. Number portability is available for fixed-line services, allowing subscribers to retain their 58 numbers when changing service providers within the same geographic area. However, porting a 58 number to a different geographic region is not permitted, as the prefix is tied to the physical location of the line.

As Aruba's telecommunications market evolves with increased VoIP adoption, some providers may offer non-geographic numbers, but the 58 code remains strictly reserved for fixed-line services in the Oranjestad area. Callers should be aware that rates for calling 58 numbers are typically standard fixed-line tariffs, which may be lower than mobile rates. For any emergency or directory assistance, local callers should use the appropriate national numbers, which are not associated with the 58 prefix.
