0120

0120 is a numeric sequence that appears in several national telephone numbering schemes, most notably as a toll-free prefix in Japan and as a geographic area code in parts of India. Its meaning and usage differ by country, reflecting how different systems allocate short numeric codes for inbound calling and regional identification.

In Japan, 0120 numbers are classified as Free Dial or toll-free numbers. They are intended to connect callers with businesses, government services, or organizations at no charge to the caller. The service provider covering the call cost is typically the company that owns the 0120 number. These numbers are part of Japan’s free-dial ecosystem, which also includes other prefixes such as 0570 and 0800.

In India, 0120 serves as a geographic STD code for Noida and surrounding areas within the National Capital Region of Uttar Pradesh. It is used to dial landline numbers domestically, for example, 0120-XXXX-XXXX. When calling from outside India, the international format would be +91-120-XXXX-XXXX, with the country code preceding the area code.

The diverse uses of 0120 illustrate how short digit strings can perform different telecom functions in different national contexts—toll-free inbound services in one country and fixed-region dialing in another.
