Registry post office · Türkiye and worldwide

Whatever changes in the register, you know first.

We read the Turkish Trade Registry Gazette, KAP and official registers abroad for the companies on your watchlist; the day a new notice is published, it is in your inbox.

Two ways to work

Add a company fast, check every fact at its source.

The same record serves both: a quick add for your watchlist or your own forms, and a sourced view for decisions that need evidence.

Quick add

Type the registry number or the name. The company’s details are filled in from the official record, so your list starts clean.

Why it matters

Not knowing is no excuse.

A change in the official register can affect your contract, your loan or your claim from the day it is published. Nobody can follow hundreds of companies by hand.

Once a change is published, you are expected to know about it.

A counterparty whose director changes, whose capital is reduced or who goes into insolvency: you are expected to know. Ulawk checks every day, catches the change, tells you and updates the company profile.

Add your companies
By registry number or by name, or as an Excel list. Companies in other countries by their local company number or LEI.
We read the history
Everything the official record holds is read and turned into a sourced profile.
We check every day
A new entry reaches your inbox the day it appears: its type, a plain summary and a link to the official record. Or into your own systems by webhook.

Who it's for

For every team that works with company data.

The same register data, four different questions. Each team follows its own list and gets its own alerts.

Banks and finance

Can this person sign this loan for the company?

Current officers at onboarding (KYB), wherever the register publishes them
Ownership and control as filed, with the source
Officer changes, capital cuts and insolvency notices across the loan book; by webhook into your systems

Law firms

Who represents the other side today?

Before signing: who holds office at the counterparty
In disputes: current address, officers, insolvency and liquidation status
In M&A: the history of shareholders, mergers and name changes

Investors and funds

Has anything changed at our portfolio company?

Capital increases and new shareholders as they are filed
Officer changes, share transfers, group links
Before investing: the record history from incorporation and related companies

Companies

Did the supplier we prepaid just go insolvent?

Add your supplier and customer list once from Excel
Liquidation, insolvency, strike-off and frequent officer changes flagged
Check who signs a contract before you sign it

Business parks and incubators follow the companies on their site from one panel, too.

Trust

Every fact linked to its source.

You do not have to wonder whether an AI summary is right. Every line in the profile is linked to the record that says it.

The official record, one click away

The source button opens the official record behind each fact. Information we cannot source does not go into the profile.

No guessing

If the register does not say it, we write “not in the record”. Calculated conclusions are marked as such. Report anything wrong from any line with one click.

Full-name sanctions screening

The company, its officers and shareholders are screened by full name against eight official lists, including the UN, OFAC, EU and UK lists. You confirm a possible hit with date of birth and nationality.

Data protection

Personal identifiers are masked. Your watchlist and notes stay in your account only; connections are encrypted and data is backed up regularly.

Frequently asked

Questions and answers

If your question is not here, write to [email protected].

What is Ulawk?

A platform that follows the companies you work with from their official records: the Trade Registry Gazette and KAP in Türkiye, official company registers abroad, and the international company identifier record (LEI) in every other country. Every fact is linked to its source.

Which countries do you cover?

Türkiye in depth; 34 countries from their official company registers; every country not listed through the international company identifier record (LEI). Each country site states plainly which data is available and which is not.

Can I link a foreign company to my Turkish company?

Yes. Add the Turkish company's foreign shareholder or parent from its own register; the two records are linked as one group and their events arrive in the same timeline and daily e-mail.

How do I learn about new changes?

Official sources are read every business day; when something changes at a company you follow, a daily e-mail tells you. A signed webhook can push it into your own systems.

Which sanctions lists are screened?

UN Security Council, OFAC SDN, EU, UK (FCDO), the US consolidated list, Switzerland (SECO), Canada (SEMA) and MASAK: companies, officers and shareholders are screened daily.

Is my data safe?

Your watch list and notes stay in your own account and are never visible to other customers. Connections are encrypted, data is backed up regularly and personal data is processed under Turkish data-protection law (KVKK).

Never miss a change.

Add your companies by registry number or from Excel; new records reach you the day they appear, with their source.
