Standardization & formatting
Rewrite addresses into a consistent, preferred format so systems can compare, store, and print them reliably.
Why it matters
Without standardization, “St.” and “Street,” or “apt 2” and “#2,” fragment the same place across duplicates, broken joins, and messy labels.
What gets standardized
Street suffixes, directional prefixes, unit designators, state/province abbreviations, and postal-code punctuation are typical targets.
USPS Publication 28 and similar national style guides define preferred abbreviations for mailing. Your internal standard may mirror those or extend them for analytics.
Parsing before polish
Good standardization starts with parsing: identify components, then apply casing, abbreviation, and ordering rules.
Preserve original input when regulations or customer preference require it, and store both raw and standardized forms.
Downstream effects
Standardized strings improve deduplication, geocoding hit rates, and CASS processing.
They also make printed labels and invoices look professional—small details that signal operational care.
