📍 Geographic Location of Pará
Overview of Area Code 91 (Belém and Pará)
Area code 91 is a geographic National Destination Code (NDC) assigned to the northeastern portion of the state of Pará, in the northern region of Brazil. The code is administered by the National Telecommunications Agency (ANATEL) and serves the state capital, Belém, along with its metropolitan region and numerous municipalities in the surrounding area. This includes cities such as Ananindeua, Castanhal, Barcarena, Marituba, Benevides, Santa Isabel do Pará, and Vigia, among others. As a geographic code, 91 is tied to a specific physical territory, and calls to numbers with this prefix are routed based on the destination's location.
Dialing Formats and Usage
Brazilian national numbers use a two-digit area code followed by an eight- or nine-digit subscriber number. For fixed lines, the format is 91 XXXX-XXXX (8 digits). Mobile numbers in Brazil have a ninth digit added, typically '9', resulting in the format 91 9XXXX-XXXX (9 digits). To call a number in the 91 area code from another Brazilian region, you must dial the national trunk prefix 0, followed by the carrier selection code (e.g., 15, 21, 31), then the area code and the subscriber number. For example, to call a fixed line in Belém from São Paulo using carrier 15, you would dial: 0 15 91 3222-0000. For mobile numbers, the same procedure applies: 0 15 91 99999-0000.
For international callers, the dialing format is: your country's international exit code (e.g., 011 from the US, 00 from most European countries), followed by Brazil's country code 55, then the area code 91 and the subscriber number. Thus, a call from the US to a Belém fixed line would be: 011 55 91 3222-0000. For a mobile, it would be: 011 55 91 99999-0000.
Geographic Coverage and Overlay
The 91 area code covers a significant portion of the state of Pará, including the capital and its metropolitan area, which is home to over 2.4 million people. It is one of several area codes in Pará; other codes include 93 (southwest), 94 (northwest), and 96 (Amapá, a neighboring state). As of now, there is no overlay code for 91, meaning that the area code is unique for its region. However, due to the growth of mobile services, ANATEL has implemented the ninth digit for all mobile numbers in Brazil, which is mandatory for all calls to mobile networks.
Caller Instructions
Local calls within the 91 area code (same code) can be dialed directly without the trunk prefix or area code, using only the subscriber number. For example, a call from a fixed line in Belém to another fixed line in Belém would simply require dialing 3222-0000. However, for mobile numbers, even local calls require the full number including the area code, as mobile numbers are not considered local in the traditional sense. Always verify the number length: fixed lines have 8 digits, while mobile numbers have 9 digits starting with 9. For international callers, it is essential to drop any leading '0' that might appear in local listings, as the international format requires only the country code and area code.
