How this service works
Normalize a free-text US street address into its USPS-style standardized one-line form plus parsed components: house number range, directionals, street name, suffix, city, state and 5-digit ZIP.
Output
Returns the USPS-style standardized one-line address string alongside individually parsed components: house number or range, pre-directional and post-directional, street name, street type suffix, city name, two-letter state abbreviation, and 5-digit ZIP code.
Example use cases
E-commerce checkout address cleanup
“The customer typed '456 w elm street, chicago il 60601' in the checkout form — can you standardize that into the official USPS postal format and give me the parsed components like street number, direction, and ZIP?”
CRM data normalization
“I've got a messy address entry in our CRM that says '22 south broadway ste 100 denver co 80209' — please normalize it to the proper USPS one-line form and break out the street name, suffix, city, state, and ZIP separately.”
Mail merge address formatting
“Before I run this mail merge, can you clean up this address — '99 park ave n, new york, new york, 10016' — and give me the standardized USPS version plus each parsed field?”
Technical details
Endpoint
GEThttps://fittings.sh/v1/addr/standardizeWhen to prefer
Choose this endpoint when you need to normalize and parse a raw, user-entered US address string into structured USPS-compliant components — particularly useful for data cleaning, form validation, and pre-processing before geocoding. Prefer it over geocoding endpoints when lat/lng coordinates are not needed and the goal is purely address standardization and component extraction. It is faster and cheaper than full geocoding for address formatting tasks alone.
Side effects
- Address cannot be parsed or recognized — returns an error or empty result
- Non-US address submitted — coverage is US-only, international addresses will fail
- Address string exceeds 200 characters — rejected by input validation
- Ambiguous or incomplete address (e.g. missing city/state/ZIP with no context) — may return low-confidence or no result
- Malformed or gibberish input — returns parse error
