registered electronic correspondence where proof of sender, recipient, timing and content matters. It can be required by a specific Ministry, regulator, application, contractual framework or sector rule.<\/p>\n<p>BTK does not describe KEP as a universal system that every company must use for every official communication. Identify the actual legal or process trigger first. For operation, BTK states that <strong>sending through KEP requires an electronic signature<\/strong>, while receive-only use does not require one for that function; a legal entity can assign one or more <em>i\u015flem yetkilisi<\/em> to operate the account on its behalf.<\/p>\n<p><span style=\"text-decoration: underline; color:#000080;\"><strong><a href=\"https:\/\/workon.com.tr\/en\/kep-address-in-turkey\/\">Read the full KEP Address in Turkey guide<\/a><\/strong><\/span>.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"KEP_Is_Not_UETS\"><\/span>KEP Is Not UETS<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>This is the most common digital-compliance mix-up.<\/p>\n<p>Since <strong>1 January 2019<\/strong>, formal electronic notifications under the Notification Law are delivered through <strong>UETS<\/strong>, not through KEP. Existing KEP addresses are not the company\u2019s UETS e\u2011Tebligat address.<\/p>\n<p><strong>For a Turkish company, UETS is not merely an optional inbox choice.<\/strong> Private-law legal entities are among the recipients subject to mandatory electronic notification. Confirm the company\u2019s allocated UETS account, authorised user, verified alert details and internal monitoring owner through the current PTT\/institutional process. A manager or ownership change does not by itself remove the legal entity\u2019s recipient status.<\/p>\n<p><strong>Activation matters:<\/strong> PTT states that a UETS address shown as \u201cAktivasyon Bekliyor\u201d is not ready to receive e-notifications until it is activated. For a legal-entity account, the transaction official can perform activation through the supported UETS access routes such as e-Devlet, e-signature or mobile signature. SMS\/e-mail alerts are useful controls, but a missing or late alert does not invalidate the electronic notification.<\/p>\n<p>UETS is primarily a notification-receipt system for messages sent by authorities authorised under the Notification Law. KEP continues as a separate registered electronic-correspondence service.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"UETS_Delivery_Rule_Five_Days_Not_%E2%80%9C24_Hours_in_KEP%E2%80%9D\"><\/span>UETS Delivery Rule: Five Days, Not \u201c24 Hours in KEP\u201d<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>PTT explains that a UETS electronic notification is legally deemed served at the end of the <strong>fifth day following the date it reaches the recipient\u2019s UETS address<\/strong>, even if it is not opened. A missing or delayed SMS\/email alert does not change that legal effect.<\/p>\n<p>Do not apply this UETS statutory rule to KEP messages, and do not use the old statement that every KEP message becomes legally read after 24 hours. The effect of a KEP message depends on the legal\/contractual context in which it is sent.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"When_Do_You_Need_Mali_Muhur\"><\/span>When Do You Need Mali M\u00fch\u00fcr?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Mali m\u00fch\u00fcr is not the company director\u2019s personal e\u2011signature.

A KEP requirement can arise from a specific law, regulator, Ministry process, tender, application, contract or business model. Sending through KEP requires an electronic signature, while receive-only use does not require one for that function. Turkish private-law legal entities are separately within the mandatory UETS electronic-notification framework."},{"Soru":"What is the difference between KEP and UETS?","Cevap":"Since 1 January 2019, statutory electronic notifications under the Notification Law are delivered through UETS. KEP remains a separate registered electronic-correspondence service. A company's KEP address should not be treated as its UETS e-Tebligat address."},{"Soru":"How is a Turkish company\u2019s UETS account activated and monitored?","Cevap":"A UETS address that is still shown as activation pending is not ready to receive e-notifications. For a legal-entity account, the transaction official can activate it through the supported UETS access routes such as e-Devlet, e-signature or mobile signature. Keep verified SMS\/e-mail alert details and an internal monitoring owner, but remember that a missing or delayed alert does not invalidate a notification."},{"Soru":"Does every unread KEP message become legally read after 24 hours?","Cevap":"No. Do not apply a universal 24-hour deemed-reading rule to KEP. The legal effect of a KEP message depends on the specific legal, regulatory or contractual context. The separate UETS framework generally deems an electronic notification served at the end of the fifth day following delivery to the UETS address."},{"Soru":"Can a foreign electronic signature ever have legal effect in Turkey?","Cevap":"Do not state that foreign electronic signatures can never have legal effect. Law No. 5070 contains recognition mechanisms, while the receiving platform or institution can also impose technical and provider-compatibility requirements. The exact transaction and signature source should be checked before relying on it."},{"Soru":"Does every company need KEP, e-signature and mali m\u00fch\u00fcr immediately after incorporation?","Cevap":"No. Build the digital stack from actual triggers. Confirm and activate the company\u2019s mandatory UETS recipient account, then determine whether planned corporate actions require secure e-signature, whether a process requires KEP and whether the company\u2019s current G\u0130B e-document workflow requires mali m\u00fch\u00fcr. Provider issuance and setup timing are not universal."}],"Ayarlar":{"mikridata_aktif":true}},"_yoast_wpseo_title":"","_yoast_wpseo_metadesc":"","_yoast_wpseo_focuskw":"","rank_math_title":"KEP vs E-Signature, UETS & Mali M\u00fch\u00fcr in Turkey: 2026","rank_math_description":"Compare KEP, secure e-signature, UETS and mali m\u00fch\u00fcr in Turkey.
