'''Programme Identification''' (PI) is a service provided by [[radio station]]s [[transmit]]tingtransmitting [[Radio Data System]] (RDS) data as part of the [[FM radio]] [[broadcast]]. The PI code allows the radio to identify the station across different [[broadcast relay station]]s. This in turn allows listeners to stay tuned to a network whilst travelling across the service area of multiple [[transmitter]]s.

The PI code is a 4-digit [[hexadecimal]] ([[16-bit]]) number. For example [[BBC Radio 1]] has PI code <code>C201</code>. (The number itself is usually not displayed on radio receivers.)
