Point Code

A Point Code (PC) is an address in the SS7 network. It can reference a SSP, STP or SCP. Depending on the SS7 variants, point code may have different Length.

The peer SS7 SSP address is referred as Destination Point Code or DPC.<br\> The local SS7 SSP address is referred as Originating Point code or OPC.<br\> We also sometimes use the term Adjacent Point Code (APC) to identify an entity connected directly to the unit with SS7 links.<br\>

<br\>The Point codes can be represented in different formats, depending on the SS7 variants:

• For ITU variants, the Point Code length is 14 bits, in a format 3.8.3
• For Japanese variants, the Point Code length is 16 bits, in a format 7.4.5
• For ANSI and Chinese variants, the Point Code length is 24 bits, in a format 8.8.8

Some regions use different formats than the dotted notation. It can either be decimal or hexadecimal. For example:

Variant	Dotted Notation	Decimal	Hexadecimal
ITU	2.14.1	4209	1071
ITU	7.250.7	16343	3FD7
ANSI	251.3.1	16450305	FB0301

You can use the tool Point Code Converter (PCC), from LogMeTT, to convert between the different formats.
