SQL Server Default Port

In this article, we are going to explore the default port number of SQL Server required for getting connected to different applications.

What is a Port? It is an endpoint of communication in an operating system. A port is always associated with an IP address of a host, and the protocol type of the communication, thereby completing the destination or origination address of a communication session. A port is identified for each address and protocol by a 16-bit number, commonly known as the port number.
When front end applications want to connect to SQL Server, port number is essential.

The default port number of SQL Server is 1433.

How to get the port number in SQL Server?

Note - The steps are shown through SQL Server 2012 environment. They are largely applicable to SQL Server 2014 too.

Step 1: Open the SQL Server Configuration Manager window through Start > All Programs > Microsoft SQL Server 2012 > Configuration Tools 



Step 2: Explore SQL Native Client 11.0 Configuration (32bit)



Step 3: Click on Client Protocols option within it  –



Step 4: Double click on TCP/IP from the right hand side pane



We will get to know the Default Port as shown here



The default port > 1433 port is the official Internet Assigned Number Authority (IANA) socket number for SQL Server. Client systems use TCP 1433 to connect to the database engine; SQL Server Management Studio (SSMS) uses the port to manage SQL Server instances across the network. You can reconfigure SQL Server to listen on a different port, but 1433 is by far the most common implementation.

Some other default SQL Server ports:

TCP 1434 – For Dedicated Admin Connection
UDP 1434 – For SQL Server Named Instance
TCP 2383 – For Default port of SSAS
TCP 2382 – For Named instances of SSAS
TCP 135 – For SSIS & T-SQL Debugger
TCP 80 and 443 – For SSRS
TCP 4022 – For Service Broker
