Included in our State Legislative Districts product are districts for both state senate (upper chamber) and state representatives (lower chamber). We offer two versions of granularity: one at the 5-digit ZIP Code level, and one at the 9-digit level. Both are listed below:

| Commercial Use | Yes | Yes |
| Future Updates | Included for 12 months | Included for 12 months |
| Granularity Level | A 5-digit ZIP Code can have multiple districts; thus, this file can have multiple rows per ZIP Code that are unique by ZIP Code, District, & Chamber. See Documentation |
Being more fine-grained, the ZIP+4 (9-digit) product has a one-to-one relationship between a ZIP+4 range and the District & Chamber combination. See Documentation |
