TURKCELL TEKNOLOJİ ARAŞTIRMA VE GELİŞTİRME ANONİM ŞİRKETİ

TURKCELL TEKNOLOJİ ARAŞTIRMA VE GELİŞTİRME ANONİM ŞİRKETİ is a anonim şirket in ISTANBUL, Türkiye that reports a consolidating parent, so its accounts form part of a larger group.

The LEI has been on record for 5 years, since 19 Oct 2021. That is about 1 year earlier than the median LEI in Türkiye, which dates from 2022 — an early adopter by local standards.

Annual re-validation is 1486 days overdue: it fell due 19 Oct 2022. An LEI that is not re-validated lapses, which does not invalidate it but marks the reference data as unverified.

The record has not changed since we began archiving it on 6 Jul 2026. Any future change to name, status, address, ownership or renewal date will be captured here, because GLEIF publishes only the current state and superseded values are otherwise lost.

The entity is registered with Central Registry Number System (MERSIS) under registry number 0478018704800018, and the LEI itself is issued and maintained by İstanbul Takas ve Saklama Bankası Anonim Şirketi, one of the Local Operating Units accredited by GLEIF.

Its ultimate accounting-consolidating parent — the highest entity in the chain that consolidates it into published accounts — is Turkcell İletişim Hizmetleri Anonim Şirketi, which is also its direct parent, so the consolidation chain is one level deep.

The LEI registration is lapsed, and the entity status (active) records whether the legal entity itself still exists. The two are independent: an LEI can lapse while the company trades on, and it can stay issued after the company has been dissolved.
