Turkey

Need reliable company identity for Turkey?

Turkey bridges Europe and Asia with a dynamic and growing economy, featuring a diverse business landscape from traditional enterprises to fast-growing digital companies.

But representing Turkish companies accurately in your product reveals specific challenges:

Registered legal names often differ from brand identities.
Business structures and naming conventions reflect Turkish regulatory requirements.
Transaction descriptors vary across Turkish banks and payment systems.
And international brand APIs rarely support Turkey's native identifiers.

Yoku makes Turkish business identity reliable and programmable.

What makes Turkey tricky for brand APIs?

Turkey has its own identification framework shaped by local regulations:

• MERSIS number – unique identifier from Turkey's Central Registration System
• VKN (Vergi Kimlik Numarası) – tax identification number used widely in B2B
• Legal forms (A.Ş., Ltd. Şti., etc.) with Turkish naming conventions
• Trade registry entries that may differ from commercial brands
• Local language considerations in company naming
• Regional business variations across Turkey's diverse markets

If you only rely on domain-based lookups, you'll miss Turkey's business identity framework.

Yoku is built around MERSIS and VKN as core identifiers.

How Yoku resolves Turkish companies

🇹🇷 Turkey-native inputs supported

Yoku can identify and enrich Turkish entities using real-world business signals:

• MERSIS number (Central Registration System)
• VKN (tax identification number)
• Registered company names
• Brand / commercial names
• Domains (when available)
• Transaction descriptors from Turkish banks and payment providers

By combining Turkish registry data, web signals, and transaction patterns, Yoku helps you:

• Enrich CRMs with verified Turkish organizations
• Normalize records across systems (legal vs brand names)
• Map payments to recognizable merchants
• Handle Turkish corporate structures and naming conventions

Turkey runs on MERSIS and VKN.
Yoku treats them as first-class identifiers.

What data you can embed in your product

When you query a Turkish company, Yoku returns structured data ready for integration:

• Logos (multiple formats & resolutions)
• Color palettes ready for theming
• Typography and font hints (when detectable)
• Company descriptions (localized when available)
• Industry mapping (NACE + local classifications)
• Location signals (HQ / regional presence when available)
• Social profiles and public presence
• Brand assets for onboarding, invoices, and dashboards
• Transaction-to-brand attribution for Turkish payment descriptors

The goal is simple: a canonical company object you can store and reuse.

Why generic brand APIs underperform in Turkey

Many "global" solutions assume:

• domain-first identification,
• Western-centric data sources,
• no understanding of MERSIS or VKN,
• and limited support for Turkish language and conventions.

In Turkey this often results in:

• missing local businesses and regional players
• confusion between legal entities and brands
• no support for Turkish corporate forms (A.Ş., Ltd. Şti., etc.)
• poor transaction recognition for Turkish descriptors

Yoku is built to handle Turkey's unique business identity framework.
