0210

0210 is a four‑digit numerical designation that appears in several unrelated contexts, most notably as a telephone prefix, a product model identifier, and a numeric code in various classification systems.

In telecommunications, 0210 is used as a telephone prefix in Japan. It is assigned to a subset of numbers within the Yamagata Prefecture, covering the city of Yamagata and surrounding municipalities. Calls to numbers beginning with 0210 are routed through the regional exchange operated by Nippon Telegraph and Telephone (NTT), and the prefix is part of the broader 02‑area code region that includes parts of the Tōhoku region.

The designation 0210 is also employed in consumer electronics as a model number. Several manufacturers have released devices—such as digital cameras, portable media players, and smartphones—under the 0210 series. These products typically share a common design language and feature set, positioning them as entry‑level or mid‑range offerings within a brand’s portfolio.

In standards and classification schemes, 0210 serves as an identifier in certain coding systems. For example, in the International Standard Book Number (ISBN) group‑identifier table, 0210 has historically been reserved for publications from specific small‑press entities, though it is rarely encountered in modern ISBN assignments. In the United Nations Standard Products and Services Code (UNSPSC), the segment “0210” may appear as part of a larger hierarchical code representing certain agricultural or horticultural products.

Because the sequence 0210 is not linked to a single, universally recognized subject, its meaning must be inferred from the surrounding context. The prefix is most commonly recognized in Japan’s telephone network, while in other industries it functions as a generic model or classification number.
