📍 Geographic Location of Queretaro
Geographic Overview
The +52 441 area code is a geographic National Destination Code (NDC) assigned to the central region of Mexico, specifically covering the city of Querétaro and its surrounding metropolitan area. Querétaro, officially Santiago de Querétaro, serves as the capital of the state of Querétaro and is a major economic and industrial hub. The area code 441 encompasses the municipality of Querétaro and nearby localities such as El Marqués and Corregidora, which form part of the Querétaro metropolitan zone.
Dialing Formats
When calling a landline or mobile number within the 441 area code from within Mexico, the national trunk prefix '01' is used, followed by the area code and the local 7-digit subscriber number. The complete national format is: 01 441 XXX XXXX. For international callers, the format is: +52 441 XXX XXXX (or 011 52 441 XXX XXXX from the US/Canada). Note that mobile numbers in Mexico are 10 digits and do not have a separate mobile prefix; they share the same NDC structure as geographic numbers. Therefore, a mobile number in Querétaro would also begin with 441.
Calling Instructions

- Long-distance calls within Mexico: Dial 01 + 441 + local number.
- Calls from the US/Canada: Dial 011 + 52 + 441 + local number.
- Calls from other countries: Dial your country's international exit code (e.g., 00 from many European countries) followed by 52, 441, and the local number.
Overlay and Numbering Considerations
As of the latest ITU-T and Mexican Federal Telecommunications Institute (IFT) updates, the 441 area code does not have an overlay. The numbering plan is closed, with 10-digit national numbers mandatory for all calls within Mexico. The 441 code is geographically fixed, meaning it does not support number portability across different geographic regions; however, mobile numbers can be ported between carriers while retaining the 441 prefix, which may cause the prefix to no longer strictly indicate the caller's location.
Economic and Telecom Importance
Querétaro is one of Mexico's fastest-growing cities, hosting major aerospace, automotive, and IT industries. The 441 area code serves a mix of residential, business, and government lines, with a high density of fiber-optic and mobile infrastructure. The region benefits from modern telecom services, including 5G coverage from major MNOs like Telcel, Movistar, and AT&T Mexico.
