The Postal Service will no longer require specific sorting for bulk mail

The US Postal Service is making it optional for bulk mailers to sort their mail into specific 5-digit, 3-digit, or ADC categories. This means large mailers will have more flexibility in how they prepare their mail for shipment.

For years, bulk mailers had to sort their mail into very specific categories to get the best rates. This was a complex and often expensive process, requiring specialized equipment or services. This change means mailers can now choose simpler, less granular sorting methods, potentially saving money and simplifying their operations.
