Can i send a thick via first class mail

In the United States, the United States Postal Service (USPS) has specific guidelines for sending packages via First Class Mail. According to the USPS, a "thick" package is generally considered to be one that exceeds the maximum weight and/or size limits for First Class Mail.

Here are the current limits for First Class Mail:

If your package exceeds these limits, you'll need to use a different shipping service, such as Priority Mail or Parcel Post, which have higher weight and size limits.

However, if your package is only slightly oversized or overweight, you may still be able to send it via First Class Mail using a special oversized or overweight package rate. These rates are typically higher than the standard First Class Mail rates.

To determine if your package can be sent via First Class Mail, you can use the USPS's online shipping calculator or consult with a postal worker at your local post office. They can help you determine the best shipping option for your package based on its size, weight, and destination.

Keep in mind that even if your package can be sent via First Class Mail, it may not be the most cost-effective or efficient option. If your package is large or heavy, you may want to consider using a different shipping service, such as Priority Mail or Parcel Post, which may offer better rates and faster delivery times.
