Stamp Pricing and Rate Changes
USPS pricing is updated annually, typically in January and mid-year, affecting the cost of Forever stamps and additional ounce stamps. Monitoring these changes helps you time bulk purchases and budget accurately for customer invoicing and marketing mailers.
If you mail large volumes, evaluate metered postage, which locks in predictable rates and simplifies postage accounting. Compare total cost of ownership, including equipment lease or purchase, against booklets and coils to identify the most economical solution for your workflow.
Best Practices for Using USPS Stamps
Proper handling, storage, and application of USPS stamps protect your investment and prevent processing delays at high-speed distribution centers.

- Verify stamp value and expiration when using older definitive stamps.
- Use a postage meter for high-volume mail to ensure accurate franking and detailed reporting.
- Check for USPS alerts about rate changes before renewing large stock.
