Rx number

An Rx number, or prescription number, is the unique identifying number assigned to a particular prescription.

In plain English

This is the number used to tell one prescription apart from every other one. It points to one specific prescribed order, not to a medicine in general.

In context

In this refill-related identifier field, it means the unique number for the specific prescription being referenced.

Situation
Requesting prescription renewals, choosing pharmacies, and following refill status
What it communicates
labels the prescription identifier field used for refills

Meaning limits

The term identifies the prescription itself, not the medicine name or the person connected with it.

Examples

“Her two prescriptions for the same medicine had different Rx numbers because the doctor issued them months apart.”

Core meaning

“When calling for a refill, give the Rx number from the bottle label.”
