Frequently asked questions
Is there a character limit for the prefix?+
Prefixes up to 20 characters are supported. Longer prefixes may reduce readability — keep to 10 characters or fewer for clarity.
Can I include a date in the prefix?+
Yes — a date-encoded prefix like 20250407- is valid and useful for date-based document tracking.
What zero-padding should I use?+
Use 6 digits (000001) for most productions. For very large collections (100,000+ pages), use 7 or more digits.
