📍 Geographic Location of Arklow
Geographic Overview
The +353 402 area code serves the town of Arklow and its surrounding hinterland in County Wicklow, on Ireland's east coast. Arklow, situated at the mouth of the River Avoca, is a historic port town and a key commercial center for north Wexford and south Wicklow. The code covers a predominantly rural and coastal area, including communities such as Avoca, Aughrim, and Tinahely, extending towards the Wicklow Mountains. Administratively, this region falls under Wicklow County Council, and the area code is allocated for fixed-line PSTN services.
Dialing Formats
When calling a number within the 402 area code from another part of Ireland, you must use the national trunk prefix 0 followed by the area code and the subscriber's 5- to 7-digit local number. For example, a local number such as 1234567 would be dialed as 0402 1234567 from anywhere within Ireland. From outside Ireland, callers should use the international access prefix (typically 00 or +), the country code 353, the area code 402 (without the leading 0), and the local number: +353 402 1234567.
For calls made within the same local area (i.e., between two numbers sharing the 402 code), it is possible to dial just the local number without the area code, depending on the specific exchange and number configuration. However, for clarity and to avoid misdialing, it is recommended to always use the full national format.
Numbering and Overlays
Irish geographic numbers are typically 7 to 8 digits long when including the area code. The 402 area code is not subject to an overlay; it is a standalone code for the Arklow geographic region. Subscriber numbers within this code can vary in length, and the total length of the national significant number (NSN) is 9 digits (including the leading 0).
Caller Instructions
For callers within Ireland: Dial 0402 followed by the local number. For example, to call a business in Arklow with the number 5551234, dial 0402 5551234.
For callers from abroad: Dial your country's international exit code (e.g., 00 from most European countries, 011 from the US/Canada), then 353, then 402, and finally the local number. For instance, from the US, you would dial 011 353 402 5551234.
It is important to note that numbers beginning with 402 are fixed-line services and are generally not portable to mobile networks. If you receive a call from a number showing +353 402, it is originating from a landline in the Arklow area, unless the caller has ported the number to a VoIP provider, which is less common for geographic numbers.
