This three-column printable EOB card clearly displays billed, allowed, and patient payment amounts for easy on-the-go reference. You can print it on 110lb cardstock to store in your wallet, glove compartment, or employee benefits folder for quick verification during provider visits or billing inquiries. All formatting specifications below align with common insurer EOB formatting standards so you can cross-reference details from your official mailed or digital EOB directly to the card without misalignment. Clause Shelf provides these specifications as educational guidance only, and all claim determinations are made exclusively by your plan administrator or issuing insurer.
Billed Amount Column Alignment Specifications for 3×5 EOB Cards
The 3×5 inch EOB card is formatted to fit standard credit card-sized wallet slots, so all column alignment must account for a 0.15 inch bleed margin on all edges to avoid cutting off text during at-home or professional printing. The billed amount column is the leftmost of the three core columns, with a fixed width of 1.2 inches, aligned 0.1 inches from the left bleed margin. The column header “BILLED” is printed in 12pt bold all-caps sans-serif font, centered at the top of the column, with a 0.2 inch blank space below the header for the first line item entry. All billed amount entries are left-aligned, formatted with standard currency punctuation, and limited to 7 characters (including dollar sign and decimal) to avoid line wrapping. If a billed amount exceeds $9,999.99, you may abbreviate to the nearest hundred and add a note on the back of the card for the full amount, though most routine care billed amounts will fit within the allocated space. Illustrative example: a billed amount of $2,450.00 for an outpatient procedure will fit perfectly in the column with 1 full character of extra space when aligned to specifications. You should cross-verify every billed amount entered on the card directly against the “billed” column on your official EOB from your insurer to avoid data entry errors, and cross-reference with your provider’s paper receipt if you have one available.

Allowed Charge Box Border Requirements for Standard EOB Cards
The middle column of the card is reserved for the allowed charge, the negotiated rate your plan has agreed to pay for in-network services, and this column is distinguished by a consistent border to prevent confusion with the higher billed amount. The entire allowed charge column, including the header and all line item entry fields, is surrounded by a 1pt dashed 20% gray border, with no border extending outside the 1.2 inch width of the column or overlapping with the billed or patient pay columns. The top of the border is aligned exactly with the top of the “BILLED” header on the left column, and the bottom of the border extends to the last line item entry field to keep all corresponding amounts matched horizontally across columns. You may add a 10% gray fill to the allowed charge header cell only to further distinguish it, but avoid filling all entry cells as this can make handwritten entries illegible. For out-of-network services where no allowed charge is listed on your EOB, you may mark the corresponding allowed charge field with “N/A” in 11pt regular font, and add a note in the patient pay column that full billed amount is your responsibility if your plan does not cover out-of-network care. Illustrative example: if your EOB lists a billed amount of $2,450 for an outpatient procedure and an allowed charge of $1,120, the $1,120 entry will sit directly across from the $2,450 billed amount, with the dashed border making it easy to identify as the plan-negotiated rate at a glance.
Patient Pay Note Font Guidelines for Readable EOB Cards
The rightmost 1.2 inch column is reserved for the patient pay amount, the total you are responsible for paying the provider after plan discounts, deductibles, coinsurance, and copays are applied. All patient pay amount entries use 11pt bold sans-serif font, left-aligned, with no stylistic formatting like italics, underlines, or colored text to ensure maximum readability in all lighting conditions, including dim provider office front desks or when viewed through a plastic wallet sleeve. The column header “YOU PAY” is printed in 12pt bold all-caps sans-serif font, aligned exactly with the headers of the other two columns to maintain visual consistency. Any short explanatory notes added to a patient pay entry (such as “applied to deductible” or “in-network copay”) are printed in 8pt regular sans-serif font, directly below the corresponding amount, with no more than 15 characters per note to avoid wrapping. If you need to add a longer note, you may use standard EOB abbreviations like “DED” for deductible, “COINS” for coinsurance, or “OOP” for out-of-pocket maximum, which are defined in the reference schedule at the bottom of the card. Never use handwritten abbreviations that are not defined on the card, as this can lead to confusion when you reference the card months after the date of service.
The table below shows the standard line item layout for the three core columns of the EOB card, with blank placeholders for you to input details directly from your official EOB:

| Line Item Description | Billed Amount | Allowed Charge | You Pay | Notes |
|---|---|---|---|---|
| Office visit, new patient | [Input from EOB] | [Input from EOB] | [Input from EOB] | Primary care provider |
| Complete blood count lab panel | [Input from EOB] | [Input from EOB] | [Input from EOB] | In-network lab |
| X-ray, single view chest | [Input from EOB] | [Input from EOB] | [Input from EOB] | Applied to annual deductible |
| Generic prescription fill, 30 day supply | [Input from EOB] | [Input from EOB] | [Input from EOB] | Standard in-network copay |
| Urgent care follow-up visit | [Input from EOB] | [Input from EOB] | [Input from EOB] | Coinsurance applied after deductible |
Front Side Form Field Labels for Single-Sided EOB Cards
All core identifying information for the claim is printed on the front side of the card, with no content printed on the back to avoid smudging against other cards in your wallet or loss of information if the card is scratched. The top section of the card, above the three core columns, includes four mandatory form field labels, all printed in 9pt bold sans-serif font, with a 0.1 inch blank entry space below each label for typed or handwritten input. The top left field is labeled “INSURER MEMBER ID”, with a width of 1 inch, for your unique plan member ID number. The top right field is labeled “DATE OF SERVICE”, with a width of 1 inch, for the date you received care. The middle field, spanning the full width between the member ID and date of service fields, is labeled “CLAIM NUMBER”, with a width of 2.6 inches, for the unique claim number listed on your official EOB, which you will need to reference if you dispute the claim or ask your plan for clarification. The fourth field, directly below the claim number field and spanning the full 3 inch width of the card, is labeled “PROVIDER NAME”, with a 0.2 inch entry space for the name of the clinic, hospital, or provider that rendered care. No additional fields are included on the front of the card to avoid cluttering the space allocated for the three core amount columns, and all fields are aligned to avoid overlapping with the column headers below.
Claim Reference Schedule Placement for Compact EOB Cards
The claim reference schedule is a small, compact section placed at the very bottom of the front of the card, 0.2 inches from the bottom bleed margin, spanning the full 3 inch width of the card, with a fixed height of 0.7 inches. The schedule is printed in 8pt regular sans-serif font, with a bold header “EOB REFERENCE” centered at the top of the schedule. The main content of the schedule lists the most common EOB abbreviations and their definitions, to help you decode notes added to the patient pay column: DED = Annual deductible, COINS = Coinsurance, COP = Fixed copay, OOP = Out-of-pocket maximum, N/A = No in-network allowed amount. The far right of the reference schedule includes a 1 inch wide field labeled “PLAN SUPPORT PHONE”, with a blank space for you to input your plan’s customer service phone number, so you can call directly with questions without having to look up your plan documents. The reference schedule is placed below the last line item of the three core columns, so it does not interfere with the alignment of billed, allowed, and patient pay amounts, and is small enough that it does not take up valuable space for additional line items. You may add one additional abbreviation definition relevant to your plan if you have extra space, but avoid adding more than one to keep the schedule uncluttered.
These specifications are provided by Clause Shelf for educational use only, and do not modify your plan terms or replace your official EOB issued by your insurer. All claim determinations, payment responsibilities, and benefit calculations are set exclusively by your plan administrator or issuing insurer. If you notice a discrepancy between the amounts on your printed card and your official EOB, contact your plan’s customer service team or HR benefits desk for clarification before making any payments.
Print one copy of the formatted 3×5 EOB card for each open claim you have, and store it in your benefits folder next to the corresponding official EOB for easy reference.
