The document number is a unique number assigned by the Recorder's Office to identify a particular document. The first part is a year prefix that indicates the year in which the document was recorded. For documents recorded before 2018, the year prefix is the last two digits of the year (YY). In 2018 it was changed to a FOUR digit year value (YYYY). Within a given year, document numbers are assigned sequentially on a daily basis as documents are taken in and processed. The second part of the document number is the sequential number assigned to the recorded document. This number gets reset to 1 at the beginning of each year. It increments by one for each document recorded. Example document numbers: 16-112233, 17-85432, 2018-112345. To see all documents with the same number in *any* year, leave the year prefix (Yr) field blank.
