Precinct maps: how to mail by precinct
Campaigns think in precincts. The post office thinks in carrier routes. Here is where to get free precinct maps in Broward, Palm Beach and Miami-Dade, and the two ways to turn a list of precincts into a mailing.
A precinct is the unit a campaign plans in. The Postal Service delivers by carrier route, one carrier's daily walk, and the two maps don't line up. This guide shows where to find precinct maps, then the two ways to mail by precinct. For the three ways to reach homes in general, start with Direct Mail 101.
You may not need a map at all
If you are mailing addressed pieces to voters, the voter file already knows each voter's precinct. Florida's statewide voter file has a field for Precinct, plus Precinct Group, Precinct Split and Precinct Suffix, and fields for the Congressional, State House, State Senate, County Commission and School Board districts (Florida Division of Elections file layout).
So a list cut by precinct is a filter on a spreadsheet. Keep the rows whose precinct is on your list and drop the rest. The same file's voting history shows who voted in past federal and state elections and how, which helps you choose precincts by turnout.
The file has no field for a city commission district. For a city race, find out from your Supervisor of Elections which precincts make up the district, then filter by those.
Your county elections office also sells voter lists:
- Broward: "Each search has a $20.00 flat-rate fee", and $6 more for a USB drive (Broward SOE price list).
- Palm Beach: a $20 processing fee for reports the office generates, and $6 for a USB drive (Palm Beach SOE public records).
- Miami-Dade: data products for "a flat fee of $20", which can be extracted by party, race, gender or age and sorted by precinct, processed in 3 to 5 business days (Miami-Dade data requests).
Where the precinct maps are
You need a map when you want to see your precincts, or when you plan to mail with EDDM, which works by route and has no names to filter.
Palm Beach County publishes its precinct shapefile as a free download, "Precinct Shapefiles (as of June 1, 2026, 812 Precincts)", with PDF and interactive maps on its Voting District Maps page.
Miami-Dade County publishes a free "Precinct" layer on its open data site, downloadable as a shapefile, GeoJSON, CSV or KML. The elections department also sells printed color maps, including countywide precincts with municipalities, at $40 a map.
Broward County is the odd one. The Supervisor of Elections offers PDF maps only: a countywide precinct map and district maps on its maps page. The downloadable file is on the county's GIS site: "Broward County Voter Precincts 2022", with 345 precincts, as a shapefile, GeoJSON, KML or CSV (Broward County GeoHub). It is the 2022 precinct set, so check it against the Supervisor's current PDF before you rely on it.
Way one: a voter list cut by precinct
This is the precise way. You mail only registered voters, only in your precincts, with their names on the piece.
- Get the voter list from your county, cut to your precincts or with the precinct field included.
- Narrow it further if you like: party, past turnout, or one piece per household.
- Send it for cleanup and printing. Addressed Marketing Mail needs at least 200 pieces.
Way two: EDDM routes that match your precincts
EDDM delivers to every address on the carrier routes you pick, with no list. The USPS route tool shows routes by ZIP Code with their counts, age band, household size and income (USPS EDDM tool). It doesn't show precincts.
So you match them by eye. Open your precinct map next to the USPS route map, pick the routes that sit mostly inside your precincts, and accept that some pieces will land just outside the line. You buy each route whole. Our route-picking guide walks through the tool, and the same spill problem with city limits.
EDDM is cheaper per piece and reaches every home, voters or not. The list reaches only voters and costs more to mail. A campaign can use both: EDDM for name recognition across a whole area, and the precinct list for the voters it most needs to reach.
A worked example with our prices
Say your five best precincts hold about 5,000 voter households.
- The list: $20 from your county.
- Print, cleanup, addressing and presort for 5,000 6" × 9" postcards with us: $1,650.
- Postage, billed at the actual USPS rate after presort, usually 29¢–40¢ per piece: $1,450 to $2,000.
That is $3,120 to $3,670 for one piece to every voter household in those precincts. Our list mail page has the larger quantities.
Or let us do it
You can cut the list and match the routes yourself with the free files above. If you'd rather hand it off, send us your precincts. We can request the list from your county, cut it to your precincts, clean it, and print and mail it, or map EDDM routes to your precincts with you.
