Ready-to-Use Sample Addresses for Fast Testing

Two fixed samples below follow the United States writing convention for South Dakota — field order, postcode length and area codes all match the real structure, so you can copy them and swap the digits:

Example 1:
2290 Vine Dr
Aberdeen, SD 57415
United States

Example 2:
628 Harbor Cir
Rapid City, SD 57751
United States

House numbers and street names are random, but the city, state abbreviation and postcode prefix come from real South Dakota ranges, so format validation passes — that does not make them real residents.

Address Structure and ZIP Matching Rules

Addresses in South Dakota follow the standard United States layout: house number first, street name second, then a city such as Sioux Falls, Rapid City, Aberdeen, the fixed state abbreviation SD, and finally a postcode in the 570xx–577xx shape, with the country line only for international mail. Postcode prefixes and area codes (605) are allocated to South Dakota specifically — mismatching the prefix across regions is the most common cause of form rejections.

United States postcodes are 5 digits. South Dakota is assigned 8 allocated prefixes (570xx, 571xx, 572xx, 573xx and more) spanning 570xx–577xx. The prefix must match the state; a mismatched prefix is the most common reason a form rejects an address.
