A remittance envelope template is a printable layout that combines a donation form and a return mailer on one folded piece of paper: the oversized flap carries the fields the donor fills in, then folds shut to seal the completed form and payment inside for mailing back. A working template gets four things right — the size and flap style, the fields printed on the form, the USPS formatting on the return side, and the security choices that keep payment data from lingering on paper it should never touch.
Pick the Size and Flap Style First
The defining feature of any remittance envelope is the oversized flap. Unlike a normal envelope’s small triangular seal, this flap extends across the entire back panel when opened, creating a printable surface for your donation form. Once the donor fills it out and folds it closed, the information faces inward.
Two flap styles are standard. A folded flap prints the form directly on the flap itself; the donor writes on it, folds it shut, and the information stays permanently attached to the envelope. A perforated or two-way flap puts the form on a detachable panel connected by a perforated edge; the donor tears off the completed form, tucks it inside with a check, and seals the envelope.
Sizes are measured closed and sealed, since that is what postal equipment sees. The #6 3/4 (3.625 × 6.5 inches) works for simple forms with a few fields and pre-set giving tiers. The #9 (3.875 × 8.875) and #10 (4.125 × 9.5) give you room for multiple designation options, recurring gift selections, and payment fields without cramping. The smaller #6 1/4 (3.5 × 6) is available but leaves little space for anything beyond the basics.
What Fields Belong on the Form
Every field costs space. Include only what you actually need to acknowledge the gift and process the payment.
Donor Contact Information
At minimum, capture the donor’s full name, mailing address, and one additional contact method such as phone or email. This lets you issue the written acknowledgment the IRS requires for any single charitable contribution of $250 or more.1Office of the Law Revision Counsel. 26 USC 170 – Charitable, etc., Contributions and Gifts That acknowledgment must state the cash amount donated, whether your organization provided any goods or services in return, and a good-faith estimate of their value if so.2Internal Revenue Service. Charitable Contributions – Written Acknowledgments Without name and address, you cannot send the receipt and the donor cannot claim the deduction.
Gift Amount and Designation
Pre-set giving levels with checkboxes reduce decision fatigue. Common tiers are $25, $50, $100, $250, and $500, with a write-in box for custom amounts. A checkbox for recurring gifts (monthly or quarterly) helps build predictable revenue. If your organization runs distinct programs, include a designation line so donors can direct their gift.
An “in honor of” or “in memory of” field with space for a name and notification address lets you send acknowledgment cards. These gifts are not automatically restricted to a specific program unless the donor explicitly says so; track them as general contributions unless your form includes a separate restriction option.
A processing-fee checkbox has become common. Language like “Add $3 to help cover transaction costs” gives donors an optional way to offset card or bank fees. Keep the checkbox unchecked by default and round the suggested addition to a whole dollar amount.
Payment Fields
For checks, print your organization’s full legal name so donors know who to write the check to. For credit or debit cards, include fields for card number, expiration date, and cardholder signature. For direct bank transfers, add routing number, account number, account type, and a signature line. Authorization language for bank debits must be clear and readily understandable, and the account holder must sign it.3Nacha. Meaningful Modernization
Leave the CVV Off the Template
This is where a lot of organizations create unnecessary risk. The Payment Card Industry Data Security Standard explicitly prohibits storing card verification values after a transaction is authorized.4PCI Security Standards Council. PCI DSS Quick Reference Guide That three- or four-digit code exists for one-time verification. Once staff process the donation, the CVV must be destroyed, and if it is printed on a paper form sitting in a file cabinet, it has not been destroyed. PCI DSS applies to every organization that collects or stores cardholder data, regardless of size or nonprofit status.
The practical approach: collect card number, expiration date, and signature on the form. Skip the CVV field entirely. If your processor requires a CVV for manual-entry transactions, have staff call the donor to collect it verbally at the time of processing rather than storing it on paper.
Choose Business Reply or Courtesy Reply
A remittance envelope only works if donors send it back. The two return-mail options differ in who pays for return postage, and the choice shapes what your template has to include.
Courtesy Reply Mail (CRM) requires the donor to put their own stamp on the envelope. You pre-print the return address but do not prepay postage. CRM requires no USPS permit and no fees to distribute.5Postal Explorer. Courtesy Reply Mail The tradeoff is friction; donors without a stamp handy may set the envelope aside.
Business Reply Mail (BRM) lets donors mail the envelope back at no cost to them. You pay postage only on envelopes that actually return, so you never pay for unused pieces. Setting up BRM requires submitting PS Form 3615 at your local Post Office or Business Mail Entry Unit, paying an annual permit fee, and establishing a Postage Due Account at your delivery post office (the account itself costs nothing to open).6Postal Explorer. Obtaining a Business Reply Mail Permit Number Your permit number, city, and state must appear on every BRM piece you distribute.
For high-volume campaigns where response rate matters more than per-piece cost, BRM is standard. For smaller mailings to an already-engaged donor base, CRM saves the permit overhead.
USPS Formatting the Template Must Include
Whether you choose CRM or BRM, the return side of your envelope has to pass through postal sorting equipment. BRM has the strictest requirements, and getting any of them wrong means rejection at the post office counter.
BRM-Specific Elements
BRM envelopes must carry a “No Postage Necessary if Mailed in the United States” imprint in the stamp area, a business reply legend with the permit number and permit holder’s city and state, and horizontal bars below the return address block.7United States Postal Service. Domestic Mail Manual – Mailing Standards Those horizontal bars can be omitted on letter-size BRM envelopes that carry an Intelligent Mail barcode.
Facing Identification Mark
A Facing Identification Mark (FIM) is a pattern of vertical bars printed in the upper right corner of the envelope, to the left of the postage area. It tells sorting machines which direction the piece faces and what kind of reply mail it is.8United States Postal Service. Facing Identification Mark (FIM) BRM envelopes without a preprinted barcode use FIM B; BRM envelopes with a preprinted ZIP+4 barcode use FIM C. CRM envelopes with a preprinted barcode use FIM A.9Postal Explorer. Elements on the Face of a Mailpiece The FIM sits in a clear zone between 1.75 and 3 inches from the right edge, with bars starting no more than 1/8 inch from the top of the piece.
Intelligent Mail Barcode
The Intelligent Mail barcode (IMb) is a 65-bar code that encodes routing and tracking information. It is required on any mailpiece qualifying for automation pricing discounts.10PostalPro. Intelligent Mail Barcode Adding an IMb to a BRM envelope lets you drop the horizontal bars from the design and can reduce per-piece postage. USPS provides free barcode fonts and encoder tools for generating compliant IMb codes.
Paper Weight and Reflectance
USPS requires envelopes sealed on all four sides to use paper with a minimum basis weight of 50 pounds on the standard 25 × 38-inch text/offset scale.11United States Postal Service. DMM Revision – Minimum Paper Basic Weight Standards That 50-pound text weight translates to roughly 20-pound bond in the system used for office paper. Standard 24-pound bond exceeds the minimum comfortably. BRM envelopes must also meet a reflectance standard; the paper cannot have red fluorescence exceeding 4.0 phosphor meter units, so barcodes read correctly under postal scanning equipment.7United States Postal Service. Domestic Mail Manual – Mailing Standards
Most organizations have their printer or mail house handle the postal formatting. Knowing what each element is keeps you from approving a proof that will fail at the counter.
Required Disclosures
If your remittance envelope mentions that gifts are tax-deductible, the IRS requires a statement that the deduction is limited to the amount exceeding the value of any goods or services provided in return.12Internal Revenue Service. Charitable Contributions – Substantiation and Disclosure Requirements
Roughly 40 states require charities to register before soliciting donations from their residents, and about half of those states mandate specific disclosure statements on the solicitation materials themselves. These statements typically tell the donor that the organization’s registration information and financial statements are available from the state attorney general or secretary of state, and that registration does not imply government endorsement. If you mail to donors in multiple states, you likely need the applicable disclosures somewhere in the mailing package. Most organizations print them on a separate insert or on the back of the outer mailing envelope, since the remittance form itself rarely has room. Penalties for soliciting without proper registration range from fines to injunctions.
Handling Envelopes After They Return
The template design ends at the printer, but the security choices it forces continue on your desk. Two people should be present when opening and logging incoming donation envelopes: one to open and record contents, another to verify amounts and prepare the deposit. The person who logs incoming checks should not be the same person who deposits them. That separation of duties prevents both honest errors and theft.
For envelopes containing credit card information, process the transaction the same day the envelope is opened. Once the charge clears, shred the form or black out the card number completely before filing. Do not accumulate unprocessed envelopes with card data in a desk drawer waiting for a batch run.
Tax-related financial records, including donation documentation that supports your annual Form 990 filing, should be retained for at least three years from the filing date. Employment tax records require a minimum of four years. After the retention period expires, destroy physical records containing donor financial data with a cross-cut shredder rather than tossing them in recycling. Apply the same retention timeline to digital copies and purge files once they expire.
