Area Code 1431 – Lalsot, Rajasthan

Geographic Coverage and Administrative Jurisdiction

The +91 1431 area code is a geographic National Destination Code (NDC) assigned to Lalsot, a town and municipality in the Dausa district of Rajasthan, India. This code serves Lalsot and its surrounding rural areas, including nearby villages and towns within the administrative jurisdiction of the Dausa district. The region falls under the Rajasthan telecom circle, and the code is used for fixed-line (PSTN) services, with some VoIP-based fixed-line providers also using this code.

Primary Cities and Local Dialing Format

Lalsot is the primary city served by this code. Other nearby towns such as Dausa, Bandikui, and Mahwa may be reached via different area codes, but within the Lalsot exchange area, subscribers share the 1431 prefix. For local calls within the same STD code area, callers can dial the 7-digit subscriber number directly without the area code. For example, to call a landline in Lalsot from within Lalsot, you would dial just the local number, e.g., 1234567.

International and National Dialing Formats

To call a Lalsot landline from another city in India, you must dial the national trunk prefix 0, followed by the area code 1431, and then the subscriber number. For instance, if the subscriber number is 1234567, the complete national dialing format is 0 1431 1234567. From outside India, callers must use the international access prefix (e.g., 00 or +), followed by India's country code 91, the area code without the leading 0, and the subscriber number. Thus, the international format is +91 1431 1234567. This format is consistent with ITU-T E.164 recommendations.

Overlay and Numbering Considerations

As of the latest telecom regulatory updates, there is no overlay code for the 1431 area. The subscriber numbers are typically 7 digits long, making the total length of an Indian landline number 10 digits (including the area code). However, in some cases, the number length may vary, but the standard format remains as described. Callers should always verify the number of digits when dialing, as errors can lead to misrouted calls.

Caller Instructions

For local callers within the Lalsot area, simply dial the 7-digit number. For national callers outside the area, always include the trunk prefix 0 before the area code. For international callers, use the plus sign (+) followed by the country code and area code, omitting the trunk prefix. It is also important to note that while mobile numbers in India are 10 digits and begin with 6, 7, 8, or 9, this area code is exclusively for fixed-line services. When calling a Lalsot landline from a mobile phone, the same dialing rules apply.
