1. A Street Name Pre Type is a word or phrase that precedes the Street Name and identifies a type of thoroughfare in a Complete Street Name. In English-language Complete Street Names, most Street Name Pre Type words are also found as Street Name Post Types.
2. A Complete Street Name usually includes either a Street Name Pre Type or a Street Name Post Type. Occasional Complete Street Names have neither ("Broadway") or both ("Avenue C Loop").
3. For numbered (or, occasionally, lettered) jurisdictional routes, the Street Name Pre Type includes the type word as well as the jurisdiction name and the administrative type of road. The following examples show the parsing of jurisdictional route names:
---Highway 101: Street Name Pre Type = "Highway"; Street Name = "101"
---County Road 88: Street Name Pre Type = "County Road"; Street Name = "88"
---Rhode Island Route 4: Street Name Pre Type = "Rhode Island Route"; Street Name = "4"
---Texas Ranch-to-Market Road 2398: Street Name Pre Type = "Texas Ranch-to-Market Road"; Street Name = "2398"
---Summit County Road XX: Street Name Pre Type = "Summit County Road"; Street Name = "XX"
---United States Highway 99: Street Name Pre Type = "United States Highway"; Street Name = "99".
4. Where a state name is used in a Pre Type as shown above, it is required to be written out in full rather than abbreviated. Similarly the words "United States" must be written out for all "US" routes and highways. The word "County" used in County routes must also be written out in full.
5. If a prepositional phrase appears between the Street Name Pre Type and the Street Name, the prepositional phrase is a Separator Element: Avenue of the Americas, Alameda de lasPulgas. Such constructions are rare in English-language Complete Street Names, but they are common in Spanish-, French-, and Italian-language street names.
6. Type words are often used as or in the Street Name (e.g. "Park Lane Circle"). Whether a type word should be placed in the Street Name Pre Type or the Street Name cannot always be discerned from the Complete Street Name itself. Sometimes the proper parsing must be inferred from the context of the street name, or checked with the street naming authority. See Complete Street Name notes for a discussion of this and other cases where a Complete Street Name might be parsed in more than one way.
7. Occasionally two or more type words occur together before the Street Name (e.g., "Bypass Highway 22.") All of the words are placed in the Street Name Pre Type, unless the Address Authority has included any of them in Street Name. If the two type words are not part of the Street Name and are not separated from each other by a directional word or other word, they are all placed in the Street Name Pre Type. See Complete Street Name notes for a discussion of this and other cases where a Complete Street Name might be parsed in more than one way.
8. To avoid confusion, this standard does not recognize any abbreviations for Street Name Pre Types. This standard requires that Street Name Pre Types be recorded and stored fully spelled out. Various inconsistent sets of abbreviations are in use, for various purposes, and none is exhaustive. USPS Publication 28 Appendix C.1 contains the best-known list of street type abbreviations. The National Fire Incident Reporting System (NFIRS) has a slightly different list. Local utilities might use other lists, and various software vendors have incorporated still other lists into their products. Terrace might be abbreviated as "Ter", "Terr", or "Tr". "Tr" might stand for terrace, trail, trace, or track. Any number of different abbreviation sets might be used for given operations or applications within an agency or firm. Therefore Street Name Pre Types should be stored unabbreviated, and related to look-up tables of abbreviations so that the proper set of abbreviations can be applied in views or export routines when needed for special purposes such as mailing labels or 9-1-1 files.
9. The USPS does not recognize the Street Name Pre Type element for standardized postal addresses. Instead, USPS Publication 28 requires that the Street Name Pre Type be combined into the Street Name, preferably unabbreviated (USPS Publication 28, Sec. 234.2, 295.2, Appendix F, Appendix H). USPS Publication 28 standards are recognized within the Postal Addressing Profile of this standard.
10. Local street naming authorities often have rules governing the use of Street Name Pre Types in their area of jurisdiction. For example, a jurisdiction might require that "Avenue" precede the Street Name if the Street Name is a letter ("Avenue C"). Where used, such rules should be documented in the Address Authority's Address Reference System Street Type Directional And Modifier Rules.
