Format guide
Delaware address format and state abbreviation
Delaware uses DE. Place the street and number on the first line, city, DE, and ZIP on the next line, and add an apartment or suite line only when present. Address format is separate from tax, account, and delivery rules.
Postal codes
DE addresses usually use a five-digit ZIP code. Test separate city, state, and ZIP fields, but do not infer delivery, tax, or account eligibility from fictional values.
How to use test data
In development you can use these samples to check field length, line breaks, international characters, and responsive layouts. For payment, identity, logistics, or compliance flows, use official sandbox data from your provider—do not submit these samples to live systems.
