Pressure piece number

The pressure piece number is used to identify the version of a contract , for example on services or rental arrangements and terms and conditions . It plays a role in consumer contracts , which are subject to frequent changes. The contract holder can use the printed part number to clearly identify a contract with certain conditions without having to individually check all the conditions that are specified in the small print . In comparative tests , for example by Stiftung Warentest , reference is often made to the printed part number of the contract to which the assessment relates.
