Company stamp maker for Turkey

A kaşe is standard on Turkish commercial paperwork, expected on invoices, contracts and official forms alongside the authorised signature.

Open the stamp maker

Turkish practice pairs the kaşe with the signature of an authorised representative, and the two together are what a counterparty looks for. Nothing requires the stamp by statute, but an invoice or contract arriving with a signature alone is commonly queried.

What a company stamp in Turkey usually carries

The company name in full, with the legal form such as A.Ş. or Ltd. Şti.
The vergi numarası, the tax number, and the vergi dairesi, the tax office.
The Ticaret Sicil number, the trade registry number.
The Mersis number on many current designs, and the registered address.

Why make it digitally

Turkish stamps carry several numbers plus an address, which lays out better rectangular and digital than cut in rubber.
Registration details change, and a re-cut costs where an edit does not.
The kaşe is used constantly, on invoices, forms and correspondence alike.

Questions

Is a kaşe required in Turkey?

Not by statute, but commercial practice treats the stamp and the authorised signature as a pair. Documents carrying only a signature are frequently queried, which makes it a practical requirement.

Which numbers belong on it?

The tax number with the tax office is the core. Most stamps also carry the trade registry number, and current designs commonly include the Mersis number.

What is an imza sirküleri?

A signature circular, a notarised document showing who is authorised to bind the company. It is a separate thing from the kaşe, and counterparties often ask for both.

This describes common commercial practice rather than giving legal advice, and practice changes. Where a specific document matters, check the requirement with the body receiving it.
