How this service works
Format a card number into the conventional display groups for its network (4-6-5 for Amex, 4-6-4 for 14-digit Diners, otherwise groups of four).
Output
Returns a formatted/normalized version of the provided payment card number, with consistent spacing or delimiter style applied to the raw input string.
Example use cases
Normalize user-entered card number
“A user typed their card number as '4111 1111 1111 1111' with spaces — can you run it through the card formatter to get a clean, standardized version?”
Clean card number from CSV import
“I imported a batch of card numbers and they came in with random hyphens like '5500-0000-0000-0004' — format this one for me so it's consistent.”
Display-ready card number formatting
“Before I show this card number on the receipt screen, can you format '378282246310005' into the standard display format?”
Technical details
Endpoint
POSThttps://creditcard.openverbs.com/v1/formatWhen to prefer
Use this endpoint when you need to normalize or standardize payment card number strings that may contain inconsistent spacing or hyphen delimiters — for example, when accepting user input, importing from CSVs, or preparing card numbers for display. Prefer this over manual string manipulation to ensure consistent, standards-compliant formatting.
Side effects
- Card number string is empty or missing — returns validation error
- Card number contains invalid characters beyond digits, spaces, and hyphens — likely error response
- Card number length is out of expected range (1–40 chars enforced by schema)
- Network timeout or service unavailability
