Veterans Day typically involves federal offices and services observing a holiday, and mail delivery by the USPS is usually suspended on that day. In practice:

• USPS: Post offices are closed and regular mail delivery is paused on Veterans Day, with exceptions for certain services like Priority Mail Express in some cases. Self-service kiosks at some locations may still be available, and you can track mail or make some online arrangements via usps.com. [citations would be provided if tool results were used]
• Other carriers: Private carriers (UPS, FedEx) operate on their own holiday schedules, often with some services limited or delayed by a day, depending on the location and service type. [citations would be provided if tool results were used]
• Banks and many government services: Banks and many government offices are typically closed as well. [citations would be provided if tool results were used]

If you’re asking about a specific Veterans Day (for example, the upcoming date this year), the exact operations can vary by year and location, so it’s best to check the USPS holiday schedule or your local post office’s hours for the day in question.
