11833.com.tr

What It Is

11833.com.tr is a Turkish unknown-number and information lookup service operated by Jan İletişim Teknolojileri. For individual users, it offers features such as “find a name by number,” “find a number by name,” “business lookup,” and “bill inquiry.” It also allows businesses to register their information in the 11833 directory database. The site states that it holds Turkey’s BTK RH-018 license.

Core Capabilities

Based on the crawled text, lookup requests are sent to the databases of Turkcell, Vodafone, and Türk Telekom at the same time, covering Turkey’s major mobile operators, with related Türk Telekom fixed-line services also mentioned. Access channels include the website, mobile, SMS, calling 11833, and app store entry points. The service emphasizes 24/7 availability, online lookup without queuing, and fast result display, but it does not publicly disclose verifiable performance metrics such as hit rate, SLA, or average response time.

Pricing and Payment

Its pricing is very clear: SMS, mobile, and web lookups all cost 4.9TL per query, including 18% KDV and 25% ÖİV. Note that a query fee is still charged even if the searched number or person has not shared information in the directory database and no result is returned. Payment is handled through local mobile payment, with Wirecard AŞ supporting Türk Telekom, Turkcell, and Vodafone mobile payments. Some operators charge a small additional fee for confirmation SMS messages.

Pros and Cons

The advantages are that it covers Turkey’s mainstream operators, provides multiple query channels, and is suitable for quickly identifying unknown callers or finding local contact/business phone numbers. Its fee rules are also repeatedly highlighted on the site. The drawbacks are also clear: queries are charged even when there is no result; no API, bulk lookup, or enterprise system integration capabilities are disclosed; it has limited value for users in China or outside Turkey; and the business registration agreement grants relatively broad rights for information use, sublicensing, and commercial exploitation, so merchants should evaluate it carefully.

Who It’s For and Access from China

It is better suited to individuals and small merchants living or operating in Turkey, for low-frequency number and business information lookups. It is not suitable as an email/SMS marketing platform or an enterprise communications API platform. The text does not provide information about access from mainland China, so its availability is unknown.
