How to find the SQL server port number


One day I got a call from my junior DBA. She asked me, how can I find out the port number for a particular server? Then our conversation started,


I asked a question to her what version of SQL server is that.

Junior DBA:

Its SQL server 2005


I told her to check the configuration manager.

Start –> all programs –> Microsoft SQL server 2005 –> Configuration Tools –> SQL server

Configuration Manager.


Junior DBA:

I don’t have direct remote access. (MSTSC)


After that, I told to check the SQL error log by using T-SQL



SP_readerrorlog 0,1,'listening','server'

Junior DBA:

I didn’t see ‘’listening’ such a word.

(0 row(s) affected)



Again I told to change the first parameter 0 to 1.

sp_readerrorlog 1,1,'listening','server'

Junior DBA:

Yep, I got it.


2011-01-19 11:36:23.340        Server Server is listening on [ ‘any’ <ipv6> 1433].

2011-01-19 11:36:23.340        Server Server is listening on [ ‘any’ <ipv4> 1433].

Here is another one method,
(For default instance)


CREATE PROCEDURE usp_getport_number
DECLARE @findport_number nvarchar(5)
EXEC xp_regread
@rootkey    =    'HKEY_LOCAL_MACHINE',
@value_name    =    'TcpPort',
@value        =    @findport_number OUTPUT
print 'The server port number = '+@findport_number

EXEC usp_getport_number
