Sequences, masks, and autonumbering

Use the sequence generator to define masks for numbered items. A mask in Civic Platform determines how a number displays to a user. For example, each new permit number might have a prefix indicating the type of permit and a date code in addition to the incremental number. A citation number can have a prefix that identifies it as a citation and not a permit, receipt number, or other incremental record in Civic Platform. After the initial implementation, you rarely need to modify masks.

This section provides details about numbering sequences and masks, and how to apply them to any item in Civic Platform that requires numbering, such as application types, invoices, and receipts.
