Zip Code

Field Length:  9

Enter the nine digit zip code for the patient's current address. If only five digits are given, record those and leave the rest of the field blank.

Refer to the U.S. Postal Service web site (see Appendix D) for the appropriate code if none is recorded in patient's record.

Code 888888888 if the patient's address is in a county other than Canada, the United States, or U.S. possessions. Code 999999999 if the patient's address is in Canada, the United States, or a U.S. possession, but the zip code is unknown.

This item is different from zip code at diagnosis in that it provides the current zip code for follow up purposes. This item should be updated as newer information becomes available.

Additional rules for determining residency may be found under the data item "CURRENT STREET ADDRESS."
