Overview of Israel's +972 55 Mobile Prefix
The +972 55 prefix is a non-geographic mobile network code assigned within Israel's national numbering plan, as administered by the Ministry of Communications. Unlike geographic area codes that correspond to specific cities or regions, the 55 prefix is used exclusively for mobile services, enabling subscribers to be reached anywhere in the country without regard to their physical location. This prefix is part of the E.164 international numbering standard, ensuring seamless interoperability with global telecommunication networks.
Technical Allocation and Numbering Format
In Israel, mobile numbers are typically 9 digits long when dialed domestically, including a leading zero. The international format for numbers under the 55 prefix is +972 55 XXX XXXX, where the leading zero is omitted. For example, a local subscriber might dial 055-123-4567, while an international caller would dial +972-55-123-4567. The 55 prefix is allocated to several Mobile Network Operators (MNOs) and Mobile Virtual Network Operators (MVNOs), including major carriers such as Pelephone, Partner (Orange), and Cellcom, as well as smaller providers like We4G and 012 Mobile. This sharing of the prefix is made possible through mobile number portability (MNP), which allows subscribers to retain their number when switching operators. Consequently, the prefix alone does not indicate a specific operator, and routing is determined by the current network subscription.
Dialing and Routing Considerations
For domestic callers, dialing a 55 number requires the trunk prefix '0' followed by the 9-digit subscriber number. For international callers, the country code +972 is used, followed by the 55 prefix and the 7-digit subscriber number (excluding the leading zero). SMS and MMS messages to 55 numbers are routed via the same international gateway, and the prefix supports full interoperability for voice, data, and messaging services. Because the prefix is non-geographic, there are no regional restrictions, and calls are routed to the subscriber's current location, whether they are at home, at work, or traveling within Israel.
Regulatory and Commercial Aspects
The Israeli telecommunications regulator has implemented number portability, which means that a number starting with 55 may be associated with any operator. This promotes competition and consumer choice. When dialing from abroad, it is essential to use the correct international format to avoid misrouting. Additionally, some VoIP and online services may require the full international number for verification purposes. For businesses, having a 55 number can be advantageous as it signals mobility and accessibility, and it is often used for customer support lines that require a mobile presence. However, it is important to note that calls to 55 numbers from landlines or mobile phones within Israel are typically charged at standard mobile rates, which may vary depending on the caller's plan.
