Area Code 36 – Rivne

Geographic Overview

The Ukrainian country code +380, followed by the national destination code (NDC) 36, routes calls to the Rivne region (Rivnenska oblast) in northwestern Ukraine. This geographic area code covers the administrative center of Rivne and its surrounding districts, including cities such as Dubno, Kostopil, Sarny, and Zdolbuniv. The region borders Belarus to the north and is an important transport and agricultural hub.

Dialing Formats

When calling a fixed-line subscriber in the Rivne region from within Ukraine, the trunk prefix '0' is used, followed by the area code and the subscriber's local number. The national format is: 0 36 XX-XX-XXX (where the total number of digits after the trunk prefix is 9). For example, a local Rivne number might be dialed as 0 36 2 123 456.

For international callers, the Ukrainian country code +380 is used, followed by the area code without the leading '0'. The international format is: +380 36 XX-XX-XXX. Thus, the same number would be dialed as +380 36 2 123 456 from abroad.

Numbering Structure and Overlays

Under the national numbering plan, geographic numbers in Ukraine are variable in length. The area code 36 is followed by a subscriber number that may consist of 6 or 7 digits, depending on the local exchange capacity and historical allocation. No overlay codes have been introduced for Rivne; the 36 code remains exclusively assigned to this geographic region. However, number portability allows subscribers to retain their numbers when changing operators, but geographic numbers generally remain associated with the original region for routing purposes.

Caller Instructions

• Local callers within Rivne: To call another fixed-line subscriber in the same area, you may need to dial the full national number (including the trunk prefix) in most cases, as direct local dialing without the area code is not standardized across all exchanges. Always use the full national format to ensure connectivity.
• Callers from other Ukrainian regions: Dial 0 36 followed by the subscriber number. For example, to call a Rivne number from Kyiv, dial 0 36 2 123 456.
• International callers: Dial your country's international access prefix (e.g., 00 from most European countries, or 011 from the US/Canada), then 380 36 and the subscriber number. For example, from the US, dial 011 380 36 2 123 456.

Regulatory and Technical Notes

The Ukrainian numbering plan is administered by the Ukrainian State Centre of Radio Frequencies (UCRF) under the Ministry of Digital Transformation, in accordance with ITU-T E.164 recommendations. Calls to geographic numbers are typically charged at standard fixed-line rates, which may vary depending on the operator and the caller's subscription plan. Emergency services in Rivne are reached via the national numbers 101 (fire), 102 (police), and 103 (ambulance), which are independent of the area code.
