İnternet Təyin edilmiş Nömrələr Təşkilatı (IANA), xüsusi istifadə üçün liman nömrələrinin rəsmi təyinatlarının saxlanmasından məsuldur.<ref>{{cite web |title=Service Name and Transport Protocol Port Number Registry |url=https://www.iana.org/assignments/service-names-port-numbers/service-names-port-numbers.txt |website=[[Internet Assigned Numbers Authority]] |access-date=28 March 2021}}</ref> Bununla birlikdə, həm tanınmış, həm də qeydiyyatdan keçmiş liman nömrələrinin bir çox qeyri-rəsmi istifadəsi praktikada baş verir. Eynilə, bir çox rəsmi tapşırıq heç vaxt istifadə edilməyən və ya artıq istifadə edilməyən protokollara aiddir.
