Assemblies for identifying a power injectable vascular access port are described. One assembly includes a vascular access port, a first identifiable feature, a second identifiable feature, and a third identifiable feature. The first identifiable feature is incorporated into the access port and identifies the access port as suitable for flowing fluid at a fluid flow rate of at least 1 milliliter per second through the access port. The second identifiable feature is incorporated into the access port and identifies the access port as suitable for accommodating a pressure within the cavity of at least 35 psi. The third identifiable feature is separated from the access port and confirms that the implanted access port is both suitable for flowing fluid at a rate of at least 1 milliliter per second through the access port and for accommodating a pressure within the cavity of at least 35 psi.
