📍 Geographic Location of Cadereyta, NL
Geographic Coverage and Administrative Jurisdiction
Area code 828 is a geographic National Destination Code (NDC) assigned to the municipality of Cadereyta Jiménez in the northeastern Mexican state of Nuevo León. This code serves the urban area of Cadereyta and its surrounding localities, including communities along the Santa Catarina River and the Monterrey–Reynosa corridor. The region is part of the greater Monterrey metropolitan area, though it maintains a distinct local exchange infrastructure under the jurisdiction of the Federal Telecommunications Institute (IFT).
Dialing Formats and Number Structure
Within Mexico, calls to Cadereyta require the national long-distance prefix 01, followed by the area code 828 and the seven-digit local number. For example, a local number such as 123-4567 is dialed as 01 828 123 4567 from other Mexican states. From within Cadereyta itself, local calls may be placed using the seven-digit number alone, depending on the carrier's local dialing plan. International callers must use Mexico's country code +52, followed by the area code and subscriber number, omitting the national trunk prefix: +52 828 123 4567.
Overlay and Numbering Considerations
As of the latest IFT updates, area code 828 does not have an overlay code, meaning it is the sole geographic code for Cadereyta. However, due to the proximity to Monterrey, some numbers may be allocated to businesses that operate across municipal boundaries. Number portability is available for geographic codes, allowing subscribers to retain their numbers when changing service providers, but the geographic tie remains—the number cannot be moved to a different area code region.
Caller Instructions
For local callers within Cadereyta, dialing the seven-digit number is typically sufficient. For callers from other parts of Mexico, always include the long-distance prefix 01 and the area code. For international callers, use +52 followed by 828 and the local number. Ensure that you drop any leading zero that might appear in local listings. For example, if a number is listed as 01 828 123 4567, international callers should dial +52 828 123 4567.
Economic and Commercial Context
