ibb

IBB is an acronym that can refer to several different organizations, institutions, or concepts, depending on the country and context. There is no single universal entity known by the acronym.

One widely recognized use is Istanbul Büyükşehir Belediyesi, the Istanbul Metropolitan Municipality in Turkey. In Turkish, the city government is abbreviated İBB (İstanbul Büyükşehir Belediyesi), and in English-language sources it is sometimes written as IBB when diacritics are not used. The body oversees municipal services, urban planning, transportation, and infrastructure for Istanbul.

In finance, IBB has been used for the Islamic Bank of Britain, a United Kingdom–based lender established in 2004 to provide Sharia-compliant banking services. It represents one of the early examples of Islamic banking in the UK.

Beyond these, IBB appears in the names of various institutes, boards, and businesses in different regions and sectors. Because the acronym is not unique, readers should rely on contextual clues—such as location, sector, or the full legal name—to identify the intended reference.
