* Suffix abbreviations are shortened forms standardized by the United States Postal Service (USPS), these are the ones the City uses as well

### Authority

* The USPS sets standards for addresses for consistency across the delivery of mail
* These are documented in [USPS Publication 28: Postal Addressing Standards](https://pe.usps.com/text/pub28/welcome.htm)

## Use

* When writing or recording a short form of a full street name
  * 1500 Market Street to 1500 Market St

### Accepted values

* Standard street suffix abbreviations available online under [Publication 28, Appendx C1](https://pe.usps.com/text/pub28/28apc_002.htm)
* Best not to encode with a period at the end
  * e.g. **ST** or **St** not St.
