As Idaho libraries continue to build and expand shared systems and continue to develop statewide library services, it is becoming increasingly important that each Idaho library has a unique and identifiable range of barcodes.

Library barcodes traditionally have a set of digits within the barcode that identify the library. This string of 4 numbers can be found in digits 2-5 of the full barcode. (See image for an example). For libraries that use a short barcode (for example, a ten-digit number), the library identifier I usually found in digits 2-3.

The Idaho Commission for Libraries is requesting libraries of all types to submit your library identifier to the Idaho Barcode Registry.
