Increase the chances your mail is delivered by filing a mail tracer: https://www.usps.com/help/missing-mail.htm
Don’t panic! There’s still hope. Chances are your package is only delayed, not lost. Yes, sometimes these delays take several days. USPS Priority Mail is advertised as a 2-3 day service, but the USPS does not guarantee it. The only “guaranteed” service offered by the USPS is USPS Priority Express. Some post offices are busier than others, some are staffed better, sort-facilities can become overwhelmed, and equipment can malfunction causing unforseen delays. All of these factors could be what’s led to your package being delayed.
When is a package considered lost? The USPS considers a package lost after 30 calendar days from the date the package entered the postal system via acceptance scan. We here at Monmouth accept claims for lost packages to be filed after 20 business days. Up until this time, we encourage you to email us, but please understand there’s almost nothing we can do to speed up the delivery of your package. We know you want them ASAP, we’re rifle builders and reloaders just like you. If it’s been 20 business days, please visit our claim form. Otherwise, we appreciate your patience. Should it be considered lost, you’ll be contacted with an option for refund or re-shipment after 20 business days.
The following information is provided as a courtesy to our customers.
If after 7 business days you have not received your package, you may file a missing mail claim, which is also called a mail tracer. There are two ways to file a mail tracer. You may contact the USPS at 1-800-ASK-USPS and navigate their customer service menu. Once on the phone with an agent, explain your package is lost and you would like to file a tracer. Alternatively, you may visit https://www.usps.com/help/missing-mail.htm and fill out the form. Once filed, keep an eye on your tracking information or opt in to receive either e-mail or text updates. Within 3 days, if you do not see movement or updates, contact us to make us aware of your situation.
Lastly, you may attempt to contact your local USPS and politely request they check their INTERNAL tracking system. Your post office may not be accustomed to being asked this question, but if they agree, you can sometimes obtain additional information not available to the general public regarding the whereabouts of your package.
