Dialing Formats and Usage

For callers within Ukraine, the local dialing format is 0 4840 followed by the subscriber number, typically 5 to 7 digits long.

As with all geographic codes in Ukraine, the tariff for calls to +380 4840 depends on the caller's operator and subscription plan, but it is generally treated as a national fixed-line call.

Overlay and Numbering Considerations

Currently, there is no overlay code for Reni; the area code 4840 is the sole geographic code for this locality. However, number portability (both fixed and mobile) is available in Ukraine, allowing subscribers to retain their numbers when changing operators, subject to regulatory conditions. This means that a number with the 4840 prefix might be routed to a different network, but the geographic association remains.
