0412

0412 is a four-digit sequence that appears in several distinct contexts, including as a numeral, a model or catalog code, and a prefix in telecommunications. The leading zero is commonly used to maintain fixed-width formatting or to indicate a prefix in data systems rather than a standalone value.

As a number, 0412 is equal to 412 in standard decimal notation. It factors as 2^2 × 103, making it an even composite number. In computing, numbers written with a leading zero can be interpreted differently depending on the language. In some programming languages that treat leading zeros as indicating octal notation, 0412 represents the octal value 412, which converts to decimal 266.

In telecommunications, 0412 is used as a prefix in some numbering plans for mobile services. For example, in Venezuela, mobile phone numbers may begin with 0412, followed by eight more digits. The exact usage and allocation of prefixes like 0412 vary by country and operator.

Beyond mathematics and telecom, 0412 can appear as a product or internal catalog code, an identifier in data sets, or a sequential numbering item in various administrative or logistical contexts. Its meaning is therefore highly context-dependent, and the same four-character string can denote different things in different domains. See also: 412, octal numeral system, Venezuelan mobile prefixes.
