Mailing Method: Priority Mail is typically faster than standard first-class mail and offers delivery within 1-3 business days.
Origin and Destination: The specific locations within California and Virginia can also impact delivery times. More remote areas may take longer than major metropolitan areas.
Time of Mailing: If you mail a letter close to a holiday or during peak mailing periods (such as the weeks leading up to Christmas), it may experience delays.
Weight and Size: Heavier or oversized letters may require additional postage and can take longer to process.
Address Accuracy: Make sure the recipient's address is accurate and complete to avoid any delays caused by incorrect or missing information.
To get a more precise estimate for a specific letter, you can use the USPS's postage calculator tool or contact your local post office for assistance.
