📍 Geographic Location of Bahia
Geographic Overview
Area code 73 is a geographic National Destination Code (NDC) within the Brazilian national numbering plan, assigned to the southern coastal region of the state of Bahia, in the Northeast Region of Brazil. This code covers a significant portion of the state's Atlantic coastline and its immediate hinterland, with the principal city being Ilhéus, followed by other important municipalities such as Porto Seguro, Itabuna, Teixeira de Freitas, and Eunápolis. The region is a major tourist destination, known for its beaches and historical significance, and also has a growing economic presence in agriculture, services, and logistics.
Coverage and Administration
The code 73 is administered by Anatel, Brazil's telecommunications regulatory agency. It serves a mix of urban and rural areas, including both coastal resorts and inland towns. The region is divided into several local calling areas, but all share the same NDC. For call routing purposes, the code is considered a single geographic rate center area, although local tariffs may vary based on distance and carrier agreements.
Dialing Formats
Brazilian national numbering uses a variable-length format. For area code 73, local subscriber numbers are 8 digits long, resulting in a total national significant number length of 10 digits (including the NDC). The complete international format is +55 73 XXXX XXXX.
- Local calls (within same city): Dial only the 8-digit subscriber number. Example: 3214 5678.
- National long-distance calls (from other Brazilian area codes): Dial 0 + carrier code + 73 + 8-digit number. Example: 0 15 73 3214 5678 (using carrier 15).
- International calls (from abroad): Dial the international access prefix (e.g., 00 from most countries, 011 from the US/Canada), then 55 (Brazil's country code), then 73, then the 8-digit number. Example: 00 55 73 3214 5678.
Caller Instructions
When calling a landline in the 73 region from outside Brazil, always drop any leading trunk prefix (0) and include the country code. For mobile numbers in the same area, note that mobile numbers also use 8 digits after the NDC, but they are identifiable by their initial digit (typically 9 for mobile). However, the dialing format remains the same. Be aware that Brazilian mobile numbers may be ported to other carriers, but the NDC remains the same as long as the number is not ported to a different geographic region.
Overlays and Recent Changes
As of the current numbering plan, there are no overlay codes for area 73. However, due to increasing demand, Anatel has implemented number conservation measures, and it is advisable to always dial the full 10-digit format (including NDC) for all calls, even local ones, to ensure proper routing in the future. This practice is already common in many Brazilian states.
