Area Code 233 – Figueira da Foz

Geographic Overview

The +351 233 area code is a geographic National Destination Code (NDC) assigned to the region of Figueira da Foz, a coastal city and municipality located in the Centro region of Portugal. This code covers the city itself and the surrounding municipalities, including Cantanhede, Mira, Montemor-o-Velho, and Soure, among others. Administratively, the area falls under the district of Coimbra, but the 233 prefix is specifically dedicated to the Figueira da Foz sub-region, ensuring efficient routing of calls within the Portuguese PSTN.

Dialing Formats

When dialing locally within Portugal, the 233 prefix is preceded by the national trunk prefix '0'. Therefore, a typical local call to a landline in Figueira da Foz would be dialed as 0 233 XXX XXX. For international callers, the country code +351 is used, and the leading '0' is dropped, resulting in the format +351 233 XXX XXX. All landline numbers under this code have a total length of nine digits when including the country code, which is standard for Portuguese fixed-line numbers.

Geographic Coverage and Local Significance

Figueira da Foz is one of the most important tourist destinations on the Portuguese Atlantic coast, known for its extensive sandy beach (Praia da Claridade) and its bustling casino. The 233 area code serves both residential and business customers in the region, including local government offices, hotels, and commercial enterprises. The code is exclusively geographic, meaning that the number is tied to a physical location, and calls are routed via the traditional circuit-switched network or over VoIP with number portability, which allows users to retain their numbers if they move within the same geographic area.

Caller Instructions

For callers within Portugal, simply dial 233 XXX XXX (omitting the trunk prefix if using a mobile phone, though including it is also valid). For international callers, dial +351 233 XXX XXX. If you are calling from a mobile phone within Portugal, it is common to include the '0' before the area code, but it is not mandatory. Always ensure you have the correct number of digits after the area code, which is six, making the total subscriber number nine digits including the country code.

As with all Portuguese geographic codes, the 233 prefix is not used for mobile services, which are assigned separate non-geographic prefixes starting with '9'. Therefore, if you receive a call from a number starting with +351 233, it is originating from a fixed line in the Figueira da Foz area.
