EDDM indicia requirements: A guide to USPS compliance

August 21, 2025Aoife Farmer

If you’ve already planned your Every Door Direct Mail (EDDM) campaign, there’s one small but critical detail that can make or break your mailing: the indicia.

This tiny block of text and symbols tells USPS that your postage has been paid and that your mailer is approved for delivery under the EDDM program. Get it wrong, and your campaign could be delayed, or rejected entirely.

This guide will walk you through exactly what the EDDM indicia is, how to format it, and where to place it so your mailers pass through USPS processing without any problems.

What is the EDDM indicia?

The indicia (pronounced in-DEE-sha) is essentially the pre-printed “stamp” that replaces individual postage stamps. It’s required by USPS for all bulk mailings, including EDDM campaigns.

Instead of paying postage for each piece at the counter, the indicia lets USPS know you’ve paid in bulk and are mailing according to EDDM rules.

For EDDM, the indicia also confirms that your campaign is Every Door Direct Mail – Retail or Every Door Direct Mail – BMEU (Business Mail Entry Unit), depending on how you’re sending it.

Why EDDM indicia matters

The indicia is more than just a formality. It’s a USPS checkpoint, think of it as your “all clear” signal for the postal service. Without the proper indicia:

Your mailer may not be accepted at drop-off
Delivery could be delayed while USPS contacts you for corrections
You might have to reprint your entire campaign (which is both costly and time-consuming)

USPS requirements for EDDM indicia

1. Correct wording

USPS requires specific wording for EDDM indicia. Below is an example of the correct EDDM indicia format for retail EDDM and BMEU EDDM:

For Retail EDDM:

PRSRT STD

ECRWSS

U.S. POSTAGE PAID

EDDM RETAIL

For BMEU EDDM:

PRSRT STD

ECRWSS

U.S. POSTAGE PAID

[City, State]

PERMIT NO. [Number]

Key differences:

Retail campaigns don’t need a permit number.
BMEU campaigns require a USPS business permit.

2. Placement on your mailer

The indicia isn’t just about what it says, it’s about where it goes, and USPS is strict about its position.

The top right corner of the address side is mandatory.
Must be aligned with the Local Postal Customer address block.
Needs at least 1/8 inch clearance from the edges of the postcard or flyer.

Tip: Always keep the indicia inside the “mailing panel” area to avoid trimming or folding issues.

3. Font & size guidelines

USPS doesn’t specify an exact font, but you should follow these best practices:

Use a clear, easy-to-read typeface (Arial, Helvetica, or similar).
Minimum 8-point font size for legibility.
All letters should be in uppercase.
Indicia should be at least 0.5” x 0.5”.

4. No handwriting or stamps

The indicia must be printed directly on the piece. It can’t be handwritten, stickered, or applied later with a rubber stamp.

5. Keep it uncluttered

The indicia must stand alone in its designated space. Avoid placing logos, graphics, or other text too close, as this can cause USPS scanners to misread it.

Other USPS design requirements to remember

While the indicia is critical, it’s part of a bigger compliance checklist for your EDDM mailer:

Address block: Must say “Local Postal Customer” in place of an individual name/address.
Mailpiece size: Must meet EDDM “flat” dimensions (min 6.125″ x 11″, max 12″ x 15″).
Bundling: Pieces must be bundled in stacks of 50-100 with facing slips (USPS forms).

If you’re unsure, USPS offers EDDM Retail Quick Reference Guides with diagrams.

Common mistakes to avoid

Wrong wording: Mixing retail and BMEU terms will result in your mailer being rejected.
Wrong placement: Indicia anywhere but the top right corner may cause delays.
Overlapping graphics: Decorative elements behind the indicia can make it unreadable.
Too small: Fonts under 8 points risk being illegible for USPS sorters.

Best practices for flawless EDDM indicia

Start with a USPS template to ensure compliance.
Work with your printer – they should know exact placement requirements.
Do a test print and check measurements before bulk printing.
Include a white background under the indicia for maximum contrast.

Frequently asked questions about EDDM indicia

Can a USPS indicia be in color?

Yes. USPS does not require the indicia to be black and white. It can be printed in color, as long as it remains clear, legible, and contrasts well with the background, so that it can be read by USPS processors.

What is the difference between a stamp and an indicia?

A stamp is a physical adhesive that represents prepaid postage for a single mail piece. An indicia, on the other hand, is a pre-printed marking that shows postage has been paid in bulk for an entire mailing. Indicia are used for large-scale campaigns like EDDM to save time and cost, so you don’t need to apply individual stamps to each piece.

Can I print my own indicia?

Yes, you can print your own indicia directly onto your mail piece. No special USPS equipment is needed. The key is to follow USPS formatting, wording, size, and placement requirements.
