USPS changes: How a new postmark rule may affect payment strategies for businesses

Adopting electronic payments, rather than mailing checks, can help businesses manage risk and improve efficiencies.

There is a new rule in effect regarding how the United States Postal Service (USPS) handles mail – and it may affect how businesses think about payments strategy.

In December 2025, the USPS implemented a rule that defines the meaning of a postmark, which is the date printed or stamped on most mailed items. Typically, a postmark indicated the day on which an item was dropped off with the USPS. Now, a postmark reflects the date the USPS processes the item at one of its processing facilities – which could be a day or more after the item was first delivered to a post office.

The potential resulting delay in postmark application could pose some level of risk for businesses sending paper check payments through the mail – particularly those needing assurance that an item will be postmarked by a certain date.

“As part of their cash management strategy, some businesses may have a practice of waiting until just before a billing or payment deadline to drop off a check payment in the mail, trusting the postmark will indicate that the item was submitted on time,” said Noelle McKenzie, product team manager in Regions Treasury Management. “But with potential delays that may result from this rule change, there is decreased visibility into when a transaction will ultimately be received and processed by the receiver, and payers may be subject to potential fees for missing payment deadlines.”

While this new risk is specifically associated with postmark dates, there are also other well-established risks tied to relying on checks and the postal service for payments – which makes the recent USPS change a timely opportunity for businesses to think about adopting alternative payment methods, according to McKenzie. “This postmark rule change signals that it may be time for businesses to think about modernizing their payments strategy and moving from paper to electronic payments.”

By adopting electronic payment solutions including ACH, wire transfers and real-time payments (RTP), businesses can reduce dependency on check payments – and reliance on the USPS.

Four advantages of electronic payments over checks

1. Speed – ACH payments generally provide predictable settlement windows, including same-day, and RTP offers essentially instant movement of funds. For businesses that prefer to wait until a specific deadline to mail a check payment, RTP may be a good alternative, as the payment is made in real time, with immediate confirmation of settlement and no waiting to see when the payment will be received. Similarly, wire transfers are a fast and secure option for high-dollar, sensitive transactions for customers who need to send and receive payments quickly.
2. Fraud mitigation – Check fraud is one of the most common types of payment fraud, and it is on the rise. Sending checks through the mail creates the opportunity for them to be lost, misdelivered, altered or stolen – and yet many businesses continue to rely on them. ACH, wire and RTP operate on secure electronic networks that may reduce exposure to certain types of risk associated with check fraud.
3. Cost-savings – There is significant cost associated with using paper checks, given the amount of manual processes involved in printing, mailing and processing. Electronic payments may reduce or eliminate these costs – as well as free up treasury and accounting teams to focus time and resources on other business priorities. In the case of ACH, in addition to being one of the lowest cost payment rails available, it can also streamline processes for businesses that have regular recurring payments, such as payroll.
4. Improved reconciliation – Electronic payments offer better remittance information and faster reconciliation than checks, which have limited remittance details that can frequently be inconsistent or incorrect. ACH and RTP have a rich structured data concept that aids in faster reconciliation and reduced manual keying errors as compared with checks. In addition, RTP payments provide confirmation of funds instantly, aiding in the reconciliation of transactions to give businesses improved visibility.

A move toward modernization

While change can present challenges, it can also bring opportunity for businesses. “The updated USPS postmark situation may present a perfect opening for businesses that have typically relied on traditional, paper-based processes to start thinking about what’s next for them,” said McKenzie. “And they don’t have to figure it all out on their own – trusted banking advisors, like the Regions Treasury Management team, can provide general insight to help evaluate and implement solutions that are suited for specific business needs.”
