Overview of Ukraine Mobile Prefix +380 73
The +380 73 prefix is a non-geographic mobile network code assigned within the Ukrainian national numbering plan, in accordance with ITU-T E.164 recommendations. Unlike geographic area codes, which correspond to specific cities or regions, the 73 prefix is used exclusively for mobile telecommunications services. Subscribers assigned numbers under this prefix are reachable via both voice and SMS services, and the numbers are not tied to a fixed location.
Technical Allocation and Numbering Format
In Ukraine, mobile numbers typically consist of a country code (+380), a two-digit mobile prefix (e.g., 73), and a seven-digit subscriber number, resulting in a total national significant number length of 9 digits (excluding the leading zero used in domestic dialing). For example, a full international format would be +380 73 XXX XX XX. Domestically, callers must dial 0 73 XXX XX XX. The 73 prefix is allocated to mobile network operators and mobile virtual network operators (MVNOs) that have been granted licenses by the Ukrainian National Commission for State Regulation of Communications and Informatization (NCCIR).
Geographic Independence and Number Portability
Because 73 is a mobile prefix, it is not associated with any specific geographic region. Subscribers can use their numbers anywhere within Ukraine and, subject to international roaming agreements, abroad. The introduction of mobile number portability (MNP) in Ukraine means that a subscriber who changes their mobile operator may retain their existing number, including those under the 73 prefix. Consequently, the prefix does not definitively indicate the current operator, only the original allocation.
Dialing Instructions for Local and International Callers
For callers within Ukraine, dialing a 73 number requires the national trunk prefix 0 followed by the prefix and subscriber number: 0 73 XXX XX XX. For international callers, the format is +380 73 XXX XX XX (or 00380 73 XXX XX XX from many European countries). When dialing from abroad, the leading zero of the national prefix is omitted. It is important to note that international calls to Ukrainian mobile numbers are typically charged at higher rates than domestic calls, and the cost is borne by the caller unless the called party has a special roaming or toll-free arrangement.
Usage and Services
Numbers under the 73 prefix support standard mobile services, including voice calls, SMS, MMS, and mobile data (3G/4G/5G). They are also used for IoT (Internet of Things) applications and machine-to-machine (M2M) communications, as operators allocate dedicated number ranges for such services. As with all mobile prefixes in Ukraine, the 73 code is subject to the same regulatory framework, ensuring interoperability and quality of service.
