What is Presorted Mail? A General Overview
Presorted mail refers to mailpieces that have been grouped and prepared in a specialized way before being handed over to the U.S. Postal Service (USPS).
When mail is not presorted, it is sent to the USPS in groups of thousands of envelopes destined for different parts of the country. USPS workers then must sort the mailpieces themselves, which is a time-consuming process. In contrast, presorted mail is organized ahead of time by zip code, region, and delivery route. This step reduces the amount of sorting the USPS does, saving them time and resources while saving money for the sender.
The USPS gives discounts to mailers who take on some of the sorting work themselves, but to qualify, the mail must be organized in very specific ways according to postal standards. Businesses must send a minimum of 500 mailpieces to qualify for presorted First-Class Mail rates. Each piece must have a complete address that matches USPS records, which helps prevent delivery errors. Addresses also need to comply with the Move Update standard, meaning they’ve been checked against the Postal Service’s national change-of-address database to make sure recipients haven’t moved. If the sender wants to qualify for greater presorted First-Class Mail discounts, they can further streamline the sorting process by adding an Intelligent Mail barcode (IMb) to each mailpiece.
Presorting benefits both senders and recipients. By preparing mail according to USPS standards, businesses and print mail services partners can qualify for discounted postage rates. The more presorted and automation-friendly the mail, the greater the savings.
What is Presorted First-Class Mail and Why Does It Matter?
When businesses talk about “presorted mail,” they’re often referring to presorted First-Class Mail, a category perfect for organizations that send large volumes of time-sensitive communications. It combines the speed and reliability of regular First-Class Mail with the cost efficiency of bulk mailing. To qualify, a mailer must send at least 500 pieces in a single batch that meet the USPS’s presorting and addressing standards. The mailpieces must have complete addresses that have been verified against USPS records, and the mail must be sorted by zip code with pieces going to the same destination placed in the same bundles or trays.
Sending mailings via presorted First-Class Mail is ideal for transactional and regulatory communications that must be delivered promptly and securely. Some examples of document types that may benefit from being delivered with presorted First-Class Mail include:
- Account statements
- Customer invoices
- Medical bills and EOBs (Explanation of Benefits)
- Compliance notices
- Policy renewal letters
- Tax forms and financial reports
For these types of documents, accuracy and timeliness are non-negotiable. Sending these documents as presorted First-Class Mail helps organizations cut postage costs without sacrificing speed. In industries like finance, healthcare, and insurance, where every communication affects customer trust and regulatory standing, presorted First-Class Mail offers efficiency and security.
The Benefits of Presorted First-Class Mail
Presorting First-Class Mail is a practical way to make mailing faster, cheaper, and more reliable.
The most immediate benefit of presorted First-Class Mail is reduced postage. The USPS offers discounted rates because presorted mail requires less handling on their end. Documents that have already been labeled correctly and grouped by zip code move through sorting facilities more efficiently, freeing up employee time for other endeavors. Businesses sending thousands of pieces can save significant amounts annually simply by meeting USPS presorting standards. When managed through a professional print mail services provider, you can capture these savings automatically.
Since presorted First-Class Mail arrives at USPS facilities already organized and ready for processing, it faces fewer intermediate steps and can enter the delivery stream more quickly than unsorted mail. Faster delivery helps businesses maintain consistent communication timelines and improve customer satisfaction, especially when mailing time-sensitive materials.
Presorting First-Class Mail often involves verification that ensures each piece has a complete address before it’s printed. Mailpiece addresses are checked against USPS databases using tools like the NCOA to catch outdated recipient information before mail goes out. As a result, fewer pieces are returned as “undeliverable as addressed” (UAA), reducing wasted postage, reprints, and the time spent tracking down customers. Further, since accurate addressing signals reliability and attention to detail, mail presorting helps your business project a more professional image.
When presorted mail is paired with an Intelligent Mail barcode (IMb), every piece can be tracked from entry into the mailstream until its final destination. This gives businesses visibility into when mail is processed, accepted, and delivered, which is valuable for reporting purposes. With this level of insight, companies can, for example, confirm when customers receive critical documents and maintain detailed mailing records for audits and customer inquiries.
Presorting mail is a cost-saving, efficiency-building strategy that enhances delivery performance and data accuracy for print mail services. It is a simple way to enhance customer communication while lowering costs and saving time.
How Presorting First-Class Mail Works, Step-by-Step
The process of presorting First-Class Mail follows a logical sequence, and when it’s managed by professional print mail services, much of it happens automatically. This is how presorted mail moves from data to doorstep:
Step 1. Data Preparation and Address Verification
The first step in the process of presorting First-Class Mail begins long before anything is printed. To create documents that are suitable for presorting, print and mail solutions partners must ensure that customer data meets address quality standards.
Mailing lists are scanned for duplicates, formatting errors, and undeliverable records. To be eligible for presorted First-Class Mail discounts, address lists must be checked using USPS-certified tools like CASS (Coding Accuracy Support System).
Documents must also meet the Move Update standard, which requires addresses to be verified against the USPS’s National Change of Address (NCOA) database. This prevents mail from being sent to customers who have moved.
Together, these address-cleaning steps improve deliverability, reduce waste, and protect postal discounts for presorted First-Class Mail.
Step 2. Document Composition and Printing
Once the mailing list is clean, document composition can begin. Using automated print mail solutions, businesses can merge verified address data with pre-approved document templates to create customized and ready-to-mail files.
Documents are printed using high-speed digital printers capable of producing thousands of pages per hour with consistent quality. During printing, each mailpiece is tagged with its corresponding IMb.
Step 3. Sorting and Grouping by Zip Code
Here are some of the ways that presorted First-Class mailpieces can be grouped together before shipping:
- 5-Digit Presort. This category is for mailpieces that are going to the same full zip code, such as “10001.”
- AADC. AADC stands for “Automated Area Distribution Center.” These groupings are for mailpieces that go to the same area, but not to the same zip code. For example, a group of presorted mail going to the Los Angeles CA 900 AADC would be going to zip codes beginning with 900 and 901.
- Mixed AADC. A mixed AADC grouping contains mail that goes to multiple AADCs (e.g., New York City and Los Angeles).
Postage discounts are greater the more specific the presorting level is. For presorted First-Class Mail, 5-digit presorting groupings offer the largest discounts, followed by AADC, then mixed AADC.
Step 4. Postage Calculation and Documentation
After sorting, postage is calculated based on weight, size, class, and presorting tier. Businesses using print mail services often rely on presorting software to automatically calculate rates. They also use presorting software to generate USPS-required documentation, such as postage statements and tray labels.
Mail that meets automation standards receives the lowest rates, while non-automation presorted pieces qualify for smaller discounts. In order to meet automation standards, presorted First-Class Mail must contain properly formatted machine-readable barcodes such as the IMb. The key advantage of working with an experienced print mail services partner is that they can implement these requirements automatically, preventing costly rejections or delays.
Step 5. USPS Entry, Tracking, and Delivery
Finally, the prepared mail is delivered to a designated USPS entry facility. At this point, the USPS scans the IMb if the mailpiece has one to begin tracking each piece through the network. Mailers can monitor delivery status in real time, verifying when pieces are processed, routed, and delivered.
