The number and street address or the rural mailing address of the patient’s residence at the time the reportable tumor was diagnosed. If the patient has multiple tumors, address at diagnosis may be different for each tumor. Additional address information such as facility, nursing home, or name of apartment complex should be entered in Addr At DX--Supplementl [2335]. Do not update this item if patient moves after diagnosis.

U.S. addresses should conform to the U.S. Postal Service (USPS) Postal Addressing Standards. These standards are referenced in USPS Publication 28, July 2008, Postal Addressing Standards. The current USPS Pub. 28 may be found and downloaded from the following website: http://pe.usps.gov/cpim/ftp/pubs/Pub28/pub28.pdf.

Canadian addresses should conform to the Canada Postal Guide. The current Canadian Postal Address standards may be found at the following website: http://www.canadapost.ca.

Addresses that are formatted to conform to USPS Postal Addressing Standards can be more properly geocoded by geographic information systems (GIS) software and vendors to the correct census tract, which is required by NPCR and SEER registries. The USPS Standards also address a number of issues that are problematic in producing precise addresses, including the use of punctuation, abbreviations, and proper placement of address elements, such as street direction, apartment and suite numbers, and unusual addressing situations. Spanish-language addresses also are covered by the USPS Standard.

Coding Instructions (summary of USPS guidelines)The address should be fully spelled out with standardized use of abbreviations and punctuation per USPS postal addressing standards (USPS Postal Addressing Standards, Pub. 28, July 2008). Upper case recommended. Mixed case allowed.

Abbreviations should be limited to those recognized by USPS standard abbreviations, these include but are not limited to (A complete list of recognized street abbreviations is provided in Appendix C of USPS Pub. 28):

APT	apartment	N	north
BLDG	building	NE	northeast
FL	floor	NW	northwest
STE	suite	S	south
UNIT	unit	SE	Southeast
RM	room	SW	southwest
DEPT	department	E	east
		W	west

Punctuation marks should be avoided, except when punctuation is necessary to convey the meaning. Punctuation normally is limited to periods when the period carries meaning (e.g., 39.2 RD), slashes for fractional addresses (e.g., 101 ½ MAIN ST), and hyphens when the hyphen carries meaning (e.g., 289-01 MONTGOMERY AVE). Use of the pound sign (#) to designate address units should be avoided whenever possible. The preferred notation is as follows: 102 MAIN ST APT 101. If a pound sign is used, there must be a space between the pound sign and the secondary number (e.g., 425 FLOWER BLVD # 72).
