Understanding SS7 Point Code Lookup

Signaling System 7 (SS7) is a telecommunication protocol used for exchanging information between network elements. It is essential for facilitating communication between various telecommunications networks. To identify signaling locations in the network, SS7 employs a distinct addressing scheme known as the Point Code. Network operators can locate signaling points by performing a Point Code Lookup, which converts a Point Code into a useful address. An overview of SS7 Point Code Lookup, including its significance, functionality, and advantages, will be provided in this article.

Importance of SS7 Point Code Lookup

The smooth operation of communication networks depends on the SS7 Point Code Lookup. The ability to pinpoint the locations of signaling points gives network administrators the knowledge they need to identify and address any potential issues with the network. Operators can follow the path taken by communication traffic, spot any congestion sites, and improve network performance by identifying the signaling stations engaged in a communication session.

How SS7 Point Code Lookup works

Each signaling point in the SS7 signaling network is identifiable by a different Point Code. Each signaling point has a specific numerical identity called a Point Code that is used to identify it in the signaling network. The Signaling Point Code (SPC), Network Indicator (NI), and Point Code (PC) are the three components that make up the Point Code. The SPC is a special identification code that the network operator assigns to the signaling point, and the NI identifies the network to which the signaling point belongs. The specific signaling point within the network is located by the PC.

The operator utilizes a specific software tool called a Point Code Lookup tool to carry out a Point Code Lookup. Using the tool, the operator can enter the Point Code and look up the signaling point’s associated address. A central database that maps Point Codes to their respective network addresses is queried by the tool. The database is updated frequently to ensure accuracy and is maintained by the network operator.

Benefits of SS7 Point Code Lookup

The SS7 Point Code Lookup provides several benefits to network operators. By identifying the location of signaling points, operators can quickly diagnose and troubleshoot any issues that arise in the network. This enables them to minimize downtime and improve network reliability.

Additionally, Point Code Lookup allows operators to optimize the network performance by identifying congestion points and re-routing traffic to less congested paths. Operators can improve the quality of service they offer to their consumers by minimizing network congestion.

In addition to the benefits mentioned in the previous section, SS7 Point Code Lookup also enables network operators to perform network planning and maintenance tasks. By identifying the location of signaling points, operators can assess the network’s capacity and determine where to add or remove signaling points. This allows them to optimize the network topology to ensure that the network can handle the expected traffic load.

SS7 Point Code Lookup is also critical for network security. The SS7 network is vulnerable to attacks, such as signaling fraud, in which unauthorized parties gain access to the network and use it to send false signaling messages. Point Code Lookup enables operators to track the origin of signaling messages and identify any fraudulent activities. By detecting and preventing signaling fraud, operators can protect their networks from unauthorized access and ensure the integrity of the signaling network.

The Point Code Lookup process is typically automated and performed by specialized software tools, which can be integrated into a network management system. The software tool retrieves the Point Code information from the signaling message and queries the central Point Code database for the corresponding network address. The database contains the mapping of Point Codes to their corresponding network addresses, which is maintained and updated regularly by the network operator.


SS7 Point Code Lookup is an essential part of communication networks that enables network operators to locate signaling points and guarantee the efficient operation of the signaling network.

It offers various advantages, including increased network dependability, higher network performance, increased network security, and the capacity to execute network planning and maintenance duties.

As telecommunications networks continue to expand and become more complicated, SS7 Point Code Lookup will remain a crucial tool for network operators to ensure the efficient and secure operation of their networks.

Frequently Asked Questions (FAQ)

What is a Point Code in SS7?

A Point Code in SS7 (Signaling System 7) is a unique numeric address assigned to signaling nodes within a telecommunication network. It is an essential component that helps in routing signaling messages between various nodes in the network, facilitating efficient communication and call setup. The Point Code acts as an identifier for each node, allowing them to exchange information and manage network services effectively.

What is the destination point code?

The Destination Point Code (DPC) is a crucial component of the global telecommunications network, specifically within the context of SS7 (Signaling System No. 7) protocol used for call routing and signaling between telecommunications networks.

What is the international signaling point code?

The International Signaling Point Code (ISPC) is a unique numerical identifier used in the SS7 (Signaling System No. 7) protocol for international signaling and communication between different telecommunications networks across the world. Just like the Destination Point Code (DPC) used for national or regional signaling, the ISPC is specific to international signaling points or nodes within the SS7 network.

What is the ANSI point code?

The ANSI Point Code, also known as the American National Standards Institute (ANSI) Point Code, is a numerical identifier used in the SS7 (Signaling System No. 7) protocol for signaling and communication within North American telecommunications networks.
