📍 Geographic Location of Santa Apolonia/Valle Hermoso, TAMPS
Geographic Coverage and Administrative Jurisdiction
The +52 894 area code is a geographic National Destination Code (NDC) assigned to the northeastern region of the state of Tamaulipas, Mexico. Specifically, it serves the municipalities of Valle Hermoso and the surrounding areas, including the locality of Santa Apolonia. This code is part of the national numbering plan administered by the Instituto Federal de Telecomunicaciones (IFT). The region is situated in the northern border area, close to the Rio Grande and the United States border, which influences its economic and social dynamics.
Primary Cities and Localities
The principal city within this area code is Valle Hermoso, a mid-sized city known for its agricultural production. The code also covers nearby communities and rural areas, including Santa Apolonia, which is a smaller locality within the same municipality. Other towns and ejidos in the vicinity may also be assigned numbers under this NDC, depending on the local exchange infrastructure.
Dialing Formats and Caller Instructions
For local callers within the 894 area code, dialing a number requires only the 7-digit local subscriber number. However, for calls originating from other area codes within Mexico, the full national long-distance format must be used: 01 894 XXX XXXX. For international callers, the format is +52 894 XXX XXXX (or 011 52 894 XXX XXXX when dialing from the US/Canada). It is important to note that Mexico's numbering plan does not use trunk prefixes like '0' or '1' in the international format; the country code +52 is followed directly by the NDC and the subscriber number.
Overlay and Numbering Considerations
Currently, there is no overlay code for the 894 area code; it is the sole NDC serving this geographic region. However, due to the proximity to the border, some users may experience cross-border mobile coverage from US carriers, which can lead to roaming charges. It is advisable for callers to be aware of their location and the network they are using. The number length is 10 digits in the national format (NDC + subscriber number), and 8 digits when dialed locally (subscriber number only).
Practical Examples
- Local call (within 894): Dial 123 4567 (if the subscriber number is 123-4567).
- National long-distance call (from Mexico City): Dial 01 894 123 4567.
- International call (from the US): Dial 011 52 894 123 4567 or +52 894 123 4567 from a mobile phone.
When dialing from abroad, always replace the '+' with the international access code of your country (e.g., 011 from North America, 00 from many European countries). Ensure you drop any leading '0' that may appear in local listings, as the international format does not include it.
