I Install SQL server in my system and I have to check on which port number SQL is working in my system
Visually you can open "SQL Server Configuration Manager" and check properties of "Network Configuration":
You can also use this query
USE MASTER
GO
xp_readerrorlog 0, 1, N'Server is listening on'
GO

This query works for me:
SELECT DISTINCT
local_tcp_port
FROM sys.dm_exec_connections
WHERE local_tcp_port IS NOT NULL
Run the below query against the database
select distinct local_net_address, local_tcp_port from sys.dm_exec_connections where local_net_address is not null
The above query shows the local IP as well as the listening Port number
PowerShell solution that shows all of the instances on the host as well as their incoming traffic addresses. The second bit might be helpful if all you know is the DNS:
ForEach ($SQL_Proc in Get-Process | Select-Object -Property ProcessName, Id | Where-Object {$_.ProcessName -like "*SQL*"})
{
Get-NetTCPConnection | `
Where-Object {$_.OwningProcess -eq $SQL_Proc.id} | `
Select-Object -Property `
@{Label ="Process_Name";e={$SQL_Proc.ProcessName}}, `
@{Label ="Local_Address";e={$_.LocalAddress + ":" + $_.LocalPort }}, `
@{Label ="Remote_Address";e={$_.RemoteAddress + ":" + $_.RemotePort}}, State | `
Format-Table
}
To check all the applications listening on all ports, there is command:
netstat -ntpl
