EDDM Postcard Printing — USPS Approved Specs & Sizes

Yes. USPS Every Door Direct Mail (EDDM) allows businesses to send postcards to every address on a selected mail route without needing a mailing list. Your postcard must meet USPS size requirements — typically a minimum of 6.125" x 11" for retail EDDM — and be properly bundled and labeled before drop-off at your local post office.

Sergio's Printing offers postcard sizes including 7" x 5" and 4" x 6" in standard formats. For EDDM-specific compliance, postcard dimensions must meet USPS minimum size thresholds. Contact us to confirm which sizes qualify for your specific EDDM mailing campaign and we'll ensure your artwork is set up correctly.

Yes. All postcard orders from Sergio's Printing support double-sided printing. This allows you to use the front for high-impact visuals, promotions, or branding, and the back for your USPS-compliant address panel, return address, postage indicia, and additional messaging or call-to-action content.

Absolutely. Sergio's Printing supports both custom design uploads and pre-made template customization. Design guidelines and templates with bleed and safe-line specifications are provided to ensure your artwork is print-ready. PDF downloads are also available for design reference before you submit your final files.

EDDM postcards are highly effective for restaurants, retail stores, beauty and spa businesses, real estate agents, event promoters, medical and dental offices, and local service providers. Any business looking to target customers within a specific geographic area benefits from EDDM's route-based delivery model without the need for a curated mailing list.

Artwork should be submitted at 300 DPI resolution in CMYK color mode. For a 4" x 6" postcard, the artwork with bleed should measure 4.25" x 6.25". Always keep critical text and design elements within the designated safe zone to avoid trimming. Sergio's Printing provides downloadable templates and guidelines to help set up your file correctly.
