Primary CTAs
These buttons are used for actions like opening an application, continuing to the next step in a process, saving or submitting a form, and completing a transaction:
They map to the primary use case for a given screen:
- Primary CTAs Should always appear first, on the left when in a horizontal row or on the top when buttons are stacked
- As a rule, there should only be one primary CTA per screen (though exceptions exist)
- Primary CTAs are active; in cases where there is a dependency or error, selecting the CTA will trigger appropriate error messaging
Secondary CTAs
These buttons are used for supporting or optional actions like canceling a request, skipping a step, or returning to a prior page. They are only used on USPS tools and applications, not on USPS.com static content pages. Secondary CTAs:
- Appear to the right of or underneath Primary CTAs
- Can appear as the only CTA on a screen
- Are active; in cases where there is a dependency or error, selecting the CTA will trigger appropriate error messaging
Inactive CTAs (Limited Use)
As a rule, Primary and Secondary CTAs on USPS.com are active. In cases where there is a dependency or error, selecting the CTA will trigger appropriate error messaging.
However, there are certain tools and applications where exceptions to this rule are necessary. These exceptions are granted on a case-by-case basis by USPS Digital Brand Marketing and in accordance with DSG governance. Contact USPS Digital Brand Marketing team to request an exception.
Ecommerce CTAs (Limited Use)
These CTAs are used for adding items to a shipping or shopping cart and completing other ecommerce transactions.
Use of the ecommerce CTA visual treatment is strictly limited. While visually distinct, the ecommerce CTA visual treatment cannot be used for visual impact outside of point-of-purchase transactions.
Ecommerce Icon CTAs
The Postal Store makes used of icons within CTAs. While this practice is not forbidden on the wider USPS.com domain, its use should be limited to ecommerce applications, specifically point-of-sale CTAs. Ecommerce Icon CTAs require both white (#FFFFFF) and USPS Digital Green (#218748), correctly sized versions of the icon being used. Below are examples of Postal Store CTA icons.
Links
A variety of different link treatments are used on USPS.com depending on link type and destination:
- Header links
- Body text links
- Lists of links
- Banner and card links
Body Text Links
Body text links may appear within a block of text, end a block of text, or encompass an entire text block. The body text specifications apply to all other link types unless noted otherwise. This is a Body Text Link example.
Color: USPS Digital Blue #3573B1
Font: Helvetica Neue
Active Link Decoration: Underline
Hover Link Decoration: No Decoration
Body text links inherit any relevant body text styling (e.g., an inline link within a bold or italic block of text would inherit that bold or italic styling). Additionally:
- Free-standing links appear in Title Case
- Body copy (embedded) links may use Sentence or Title Case (contextual)
- Links should be clear, concise, and action-oriented
- - Lead with an action verb whenever possible
- - Tell users what to expect
- - Fragments OK, no need for complete phrases
- Do not use links in error messaging (with the exception of the Alert Bar)
Icon Combo CTAs (Limited Use)
These limited-use icon/CTA combos force the user to select between mutually exclusive application flows.
Icon Combo CTAs include a default and hover/selected state to further aid in making a user's selection unambiguous. On mobile, icon CTAs are used.
