Area Code 47 – Ústí nad Labem Region

Overview of Area Code +420 47

The telephone area code 47 is a geographic National Destination Code (NDC) within the Czech Republic's national numbering plan, which adheres to ITU-T E.164 standards. When dialed internationally, the full number is prefixed with the country calling code +420, resulting in the format +420 47x xxx xxx. This code serves the Ústí nad Labem Region (Ústecký kraj), located in the northwestern part of Bohemia. The region is known for its industrial heritage, scenic landscapes along the Elbe River, and the Ore Mountains.

Geographic Coverage and Primary Cities

The 47 code covers a significant portion of the Ústí nad Labem Region, including the regional capital Ústí nad Labem and other key municipalities such as Děčín, Teplice, Litvínov, and Most. These cities form a dense urban and industrial corridor. The code is assigned to fixed-line PSTN services, and numbers under this code are typically used by residential, business, and government subscribers within the designated geographic area.

Dialing Formats and Instructions

For callers within the Czech Republic, the national trunk prefix is not used; instead, callers dial the nine-digit subscriber number directly, which includes the area code. For example, a local call to a subscriber in Ústí nad Labem would be dialed as 47x xxx xxx. For international callers, the country code +420 is added, and the leading zero (if any) is omitted. Thus, an international call would be placed as +420 47x xxx xxx. It is important to note that the Czech numbering plan does not use a trunk prefix '0' in the international format; the number is always dialed in its full national format without any leading zero.

Numbering Plan and Overlays

The Czech Republic employs a closed numbering plan, meaning that all subscriber numbers, including those under the 47 code, have a fixed length of nine digits. There are no overlay codes in the traditional sense; the 47 code is the sole geographic code for the region. However, number portability allows subscribers to retain their numbers when changing operators, even if they move outside the geographic area, though the number remains associated with the original tariff and routing.

Practical Information for Callers

When calling from abroad, ensure you have the correct international access code (e.g., 00 from most European countries, or 011 from North America) followed by 420 and the nine-digit number. For example, to call a number in Teplice, you would dial +420 47x xxx xxx. Calls to geographic numbers are typically charged at standard landline rates, which may vary depending on the caller's operator and the destination. Always verify the full number with the recipient, as numbers within the 47 code are not portable across geographic codes.
