Sevendigit

Sevendigit is a term used in multiple contexts, including mathematics, information technology, telecommunications, and branding. In mathematics and numerical data, a seven-digit number is any integer from 1,000,000 to 9,999,999. When stored as a string, it is a sequence of seven decimal digits, typically without a leading zero; seven-digit identifiers are widely used for fixed-length fields such as account numbers and product codes, where a consistent width simplifies formatting and sorting.

In telecommunications, seven-digit dialing refers to local-number formats in which the area code is not required for calls within the same locality. Some numbering plans also use seven-digit local numbers in vanity formats or internal extensions within organizations.

As a branding element, sevendigit appears as a proper name or stylized brand in various contexts. A notable example is 7digital, a British online music store and streaming service established in 2004, which provides a digital music catalog, distribution services to labels, and developer APIs. The use of seven-digit forms in branding often aims to convey simplicity or a numeric motif.
