{{Short description|ICR standard for subdivision codes}}

'''ICR 110''' is the [[International Codes Registry]] standard for administrative subdivision identifiers.

ICR 110 identifies first-level and selected lower-level administrative divisions. Each code begins with the parent [[ICR 100]] territory code, followed by a hyphen and a stable subdivision element.

Examples:

<pre>
NL-ZH
RO-B
RO-IF
</pre>

The subdivision element may contain one to three letters or digits. Existing national abbreviations may be retained when they are stable and do not conflict within the parent territory.
