Faxed prescription orders shall contain which identifying information?

• A. The prescriber's email address.
• B. The receiving pharmacist's license number.
• C. The identifying number of the sending fax machine.
• D. The patient's home address.

Answer: (C)

When a prescription is sent by fax, there needs to be a reliable way to verify where it came from and keep a traceable record. The unique identifying number of the sending fax machine serves as that source marker, tying the transmitted prescription to a specific device and location. This supports authenticity, accountability, and easier investigation if questions arise about the transmission. An email address for the prescriber isn’t part of the faxed record, the receiving pharmacist’s license number isn’t used to identify the source of the fax, and the patient’s home address is private and unnecessary for tracing the order. So the sending fax machine’s identifying number is the information that ensures the origin of the fax can be confirmed and tracked.
