What does an address in Delaware look like?
A typical Delaware mailing address follows the standard US format — house number and street, city, the state code DE, then a 5-digit ZIP code:
517 Maple St, Wilmington, DE 19801
Here 19801 is a real Wilmington ZIP code, so the city, state and ZIP pass region-consistency validation. The street and house number are sample data — use the generator above to produce more random Delaware addresses with names and phone numbers, or copy individual fields straight into your form.

Delaware: tax-free and the corporate capital
Delaware charges no sales tax at any level, making it the East Coast counterpart to Oregon for zero-tax checkout testing. It is also the registered home of over a million companies, so Wilmington (198xx) business addresses are ubiquitous in real-world billing data. The whole state uses a single area code, 302, and ZIP codes run 19701–19980.
How to fill Delaware addresses into forms
- Street Address takes the house number and street name.
- City must be one of the Delaware sample cities, e.g. Wilmington, Dover, Newark.
- State accepts either the full name "Delaware" or the two-letter code "DE".
- ZIP Code has to match the selected city — mixing regions is the most common validation failure.
Responsible use
